The name Pleiocarpidia was coined by K. SCHUMANN (ENGLER und PRANTL, Natürliche Pflanzenfamilien, Nachträge I, p. 314, 1897) for a genus described in 1873 by HOOKER f. (BENTHAM et HOOKER, Genera Plantarum II (1), p. 71) as Aulacodiscus: HOOKER’S genus had to be rebaptized, because the name Aulacodiscus had been used already in 1844 by EHRENBERG for a genus belonging to the Diatomeae. A proposal made by O. KUNTZE(POST et KUNTZE, Lexicon, 1904) to change the spelling of the name introduced by SCHUMANN in Pliocarpidia can not be accepted, as there is no rule prescribing the transcription of the Greek diphthong in the manner advocated by the proposer. The plant on which HOOKER’S genus was founded, a small tree not uncommon in the Malay Peninsula, had been...

A new Staurogyne from the Territory of Papua

Ano: 1938

URL: http://www.repository.naturalis.nl/record/524807

The new species described below belongs like St. leplocaulis Brem. (in Nova Guinea, new ser., 8: 129. 1957) to the subgenus Telrastichum, which is characterized by the presence in each of the ovary cells of circ. 60 ovules arranged in four rows and by the lower flowers of the inflorescence being subtended by ordinary leaves. The new species is easily distinguishable from St. leptocaulis by its larger and relatively wider leaves and by its obovate-orbicular bracts.

Additional notes on the Rubiaceae of Surinam

Ano: 1959

Since the appearance of my „Notes on the Rubiaceae of Surinam” (in Rec. d. Trav. bot. néerl. XXXI, 1934, 248; also in Meded. Bot. Mus. Herb. Utrecht no. 11, 1934) a number of species and varieties new to the flora of that country have come to light. The majority have been collected by Mr. Rombouts during the 1935/36 expedition of the Boundary Commission who is surveying at present the border in the southern part of the colony; they were found along the River Corantyne and in the savannahs in the south-western part. One species was secured by Dr. Lanjouw, and has been mentioned already in his „Additions to Pulle’s Flora of Surinam I” (in Rec. d. Trav. bot. Néerl. XXXII, 1935, 258) and one, represented by a rather poor fruiting specimen collected years ago...

An annotated list of the Acanthaceae collected by Miss W. M. A. Brooke on her travels in Bolivia

Ano: 1936

URL: http://www.repository.naturalis.nl/record/534686

The Acanthaceae collected by Miss W. M. A. Brooke in Bolivia are listed. Five new species are described, viz. Stephanophysum brookeae, St. macrandrum, Sarotheca glutinosa, S. boliviensis and Lophothecium boliviense. Moreover, for the species belonging to the group Genuini Ebracteolati of Dipteracanthus Nees a new genus Ulleria is created. The following new combinations are proposed: Ulleria geminiflora (Ruellia geminiflora H.B.K.), U. angustifolia (Dipteracanthus angustifolius Brem.), U. surinamensis ( D. surinamemis Miq.), and further Stemonacanthus euanthus (Ruellia euantha Lindau), Arrhostoxylum kuntzei (Ruellia kuntzei Lindau), Sarotheca archeri (Justicia archeri Leonard), S. cystolithosa (J. cystolithosa Leonard) and Saglorithys polygonoides (J....

Linné’s views on the hierarchy of the taxonomic groups

Ano: 1969

URL: http://www.repository.naturalis.nl/record/534853

It is the fate of most historic personalities that in the course of time their work sinks almost completely into oblivion, and that the few lingering reminiscences of their achievements are transmitted to later generations in the form of second- or third-hand quotations, usually mixed with more or less anecdotic episodes from their life. It must be admitted that LINNÉ occupies in this respect a comparatively favourable position, for most educated people will remember that they heard in their school days of at least three things which are credited to him, in the first place that he produced a classification of the plant kingdom which is based on the number of stamens and carpels, the so-called sexual system, in the second place that he was the first who...

New Bornean Acanthaceae

Descriptions are given of the tribe Lepidagathideae, that had already been proposed in an earlier paper, and of an entirely new tribe related to the latter, the Borneacantheae. The last-named tribe comprises so far but a single genus, Borneacanthus, based on B. grandifolius; it further includes B. angustifolius, B. paniculatus, B. stenothyrsus, B. parvus and B. mesargyreus (Hall. f.) Brem. (Strobilanthes mesargyreus Hall. f. = Filetia mesargyrea Brem.), and is confined to Borneo. Another new genus, Cosmianthemum, a near ally of Pseuderanthemum, seems to have an even narrower geographical distribution, for it has been found so far only in the western part of Borneo. It is based on C. magnifolium, and comprises in addition C. latifolium, C. angustifolium, C....

Notes on some Acanthaceous genera and species of controversial position

Ano: 1960

URL: http://www.repository.naturalis.nl/record/524509

The genus Stenandriopsis was created by S. Moore in Journ. of Bot. 44: 153. 1906 for a plant collected first by Vaughan Thompson and afterwards by Baron in an unspecified part of Madagascar. As the plate by which the description is accompanied depicts the specimen collected by Baron (n. 6708), the latter is to be regarded as the type. Stenandriopsis was referred by its author to the Justicieae, but this tribe is apparently accepted by him in the delimitation it received in BENTHAM and HOOKER’s “Genera Plantarum”, and as it is in this sense a most heterogeneous mixture, this does not greatly enlighten us. Of more importance is that Moore compares it with Crossandra Salisb. and Stenandrium Nees, i.e. with genera belonging to my subfamily Acanthoideae and...

Notes on the Acanthaceae of Surinam

Ano: 1956

URL: http://www.repository.naturalis.nl/record/535222

LINDAU in his monograph of the family in the first edition of ENGLER & PRANTL distinguished four subfamilies: Nelsonioideae, Mendoncioideae, Thunbergioideae and Acanthoideae. The first three subfamilies afterwards were united by VAN TIEGHEM and separated from the Acanthaceae under the name Thunbergiaceae. WETTSTEIN agreed with VAN TIEGHEM in so far that he too accepted a nearer affinity between the first three subfamilies, but instead of regarding the whole as a family distinct from the true Acanthaceae he considered them as a subfamily Thunbergioideae, reducing the three subfamilies of LINDAU to tribes. In this way, however, he had, apparently unwittingly, returned to the standpoint taken in by NEES, whose Anechmatacantheae and Echmatacantheae...

Notes on the Rubiaceae of Surinam

Ano: 1938

URL: http://www.repository.naturalis.nl/record/534841

In my revision of the Rubiaceae in Pulle’s Flora of Surinam two genera, viz. Pagamea and Perama, which are now usually included in this family, are relegated to an appendix. On account of its superior ovary Pagamea was formerly reckoned to the Loganiaceae, from where it was referred to the Rubiaceae by Baillon and K. Schumann, who were of opinion that its solitary ascending ovules, and the valvate aestivation of the corolla lobes assigned it a place among the Psychotrieae. I think however that they overestimated the value of these characters, which are of a rather general nature, and that Pagamea both in the structure of its inflorescence and in that of its flowers shows so little resemblance to the Psychotrieae that it is impossible to include it in this...

Notes on the Rubiaceae of tropical Asia

Ano: 1934

URL: http://www.repository.naturalis.nl/record/535158

The genus Rutidea was founded by De Candolle in 1807 on a West African plant. Twenthy-three years later in the ”Prodromus“ (IV, p. 495, 1830) he tentatively admitted a second species: it was based on a plant from Penang which he had seen in Blume’s herbarium, where it was labelled ”Rutidea? mollis Bl.“. Subsequently several other species have been added, but as none of them were Asiatic, it was, perhaps, no wonder that Bentham and Hooker f. in their ”Genera Plantarum“ (II, 1, p. 116, 1873) made no mention whatever of Blume’s plant, and regarded the genus as confined to tropical Africa. Hiern, who in the ”Flora of tropical Africa“ gave an excellent description of the genus, and enumerates ten species from tropical Africa, said that it is known from...

On the identity of the genera Mapouria Aubl. and Grumilea Gaertn. (Rubiaceae, Psychotrieae)

Ano: 1937

URL: http://www.repository.naturalis.nl/record/526345

The generic name Mapouria Aubl. should be applied to those Psychotrieae in which the following set of characters is found: deciduous stipules, heterostylous flowers, seeds without a longitudinal intrusion on the commissural side and an endosperm in which the spermoderm penetrates in the form of a network which may be confined to the commissural side but which, as a rule, extends over the whole surface. This means that it should be used also for those species which up to now have been included in Grumilea Gaertn. It need not be given up in favour of Psychotria. The name Psychotria may provisionally be retained in the conventional sense, with the proviso, however, that species with deciduous stipules or without a single or double longitudinal intrusion at...

On the position of Platycarpum Humb. et Bonpl., Henriquezia Spruce ex Bth. and Gleasonia Standl

Ano: 1961

Some time ago the “Institute Agronómico do Norte, Belem, Pará, Brazil” sent me a set of specimens for identification among which I detected a new species of Henriquezia Spruce ex Bth. This discovery induced me to study once more and now in somewhat more detail the relation between this genus and the nearly related Platycarpum Humb. et Bonpl. and the position these two genera occupy with regard to the habitually rather similar Gleasonia Standl., a subject to which I had already paid some attention at an earlier occasion, and on which I had reported in a note which is to be found at the base of p. 16 of my work on “the African Species of Oldenlandia L sensu Hiern et K. Schumann” in Verh. Kon. Ned. Akad. v. Wetensch., Sect. 2, 48, no 4, 1952. By the good...

On the systematic position of the Australian nelsonias and thunbergias and of the Ruellia species which by domin were referred to Aporuellia clarke

Ano: 1957

URL: http://www.repository.naturalis.nl/record/535119

The reduction of Nelsonia campestris R.Br. to N. canescens (Lam.) Sprengl. was not justified; N. campestris is a species confined to Australia or, perhaps, to Australia and New Guinea; arguments are adduced against Bentham’s view that N. campestris would be a common tropical weed. Thunbergia arnhemica F. v. Müll. was erroneously sunk in Th. fragrans Roxb.; the latter is confined to India and Ceylon and Th. arnhemica to Australia. Ruellia acaulis R.Br., R. australis Cav., R. pumilio R.Br. and R. spiciflora F. v. Müll. ex Bth. are transferred to a new genus Brunoniella, which is confined to Australia.

On Urophyllum Wall. (Rubiaceae) and its nearest allies

Ano: 1964

URL: http://www.repository.naturalis.nl/record/535072

All botanists acquainted with the family Rubiaceae will agree that the present subdivision is far from satisfactory and that more than one of its tribes are either artificial or ill-defined or both. The genera dealt with in this paper are said to belong to the Mussaendeae, but the distinction between this tribe and the Hedyotideae as defined by BENTHAM and Hooker f. (Oldenlandieae K. SCh.) rests merely on the succulence or non-succulence of the fruit and must therefore be regarded as both artificial and ill-defined: artificial, because from a morphological point of view the difference between dry and fleshy fruits is certainly not more important than that between the capsular and schizococcous fruits brought together in the first group and not more weighty...

Pleiocraterium genus Novum Rubiacearum Hedyotidearum

Among the most remarkable finds made by Dr. van Steenis in the higher parts of the mountains of North Sumatra are a number of cushion plants. Two of these he recognized as Rubiaceae nearly related to Hedyotis verticillaris W. et A., a species occurring in similar habitats in the Nilgiri Hills, India, and in Ceylon. Hesitating, however, to express a definite opinion on their taxonomic position, he sent the material to me for further investigation. As I had occupied myself already for some time with the genus Hedyotis L. and its allies, this investigation offered me a Wellcome opportunity to test some of the principles which I had laid down for the subdivision of this group. Apart from the characters of the fruit I lay stress on the position of the...

Psychotria farameoides Brem. n. spec. (Rubiaceae)

Ano: 1939

URL: http://www.repository.naturalis.nl/record/534778

Among the Rubiaceae collected by Dr. P. C. Heyligers near Jodensavanne, a village on the Suriname River, I found a new Psychotria species which I provisionally described as Psychotria farameoides. At the time I made this description, it was not my intention to publish it, as on account of the absence of fruits it was incomplete. As in this genus the most trustworthy characters for the determination of the position of the species are found in the fruit, especially in the pyrene and in the endosperm, it is, in my opinion, undesirable to publish descriptions in which these characters are not recorded. However, as Dr. Heyligers wanted to mention this species in the description of one of the vegetation types found in the savannas of this region, and as after...

Remarks on the position of some Australian Acanthaceae

Ano: 1962

URL: http://www.repository.naturalis.nl/record/535011

The taxonomic position of some Australian Ruelliinae and Justiciinae is discussed. In Dipteracanthus two new combinations are proposed, viz. D. primulaceus (F. v. Müll, ex Bth.) Brem. and D. corynothecus (F. v. Mül, ex Bth.) Brem., both originally described in Ruellia, and one new species and one new variety are described, viz. D. sessiliflorus Brem. and D. corynothecus (F. v. Müll, ex Bth.) Brem. var. grandiflorus Brem. The Australian specimens that hitherto have been referred to Justicia procumbens L (= Rostellularia procumbens (L) Nees) will have to be referred to various other Rostellularia species. Justicia kempeana F. v. Müll, is removed to a new genus Sarojusticia, which necessitates the new combination S. kempeana (F. v. Müll) Brem.

Remarks on the position, the delimitation and the subdivision of the Rubiaceae

Ano: 1962

It is often assumed that the delimitation and the subdivision of the various families which have been distinguished in the Angiosperms, do no longer offer serious difficulties. They would belong to those objects of study for which already long ago a fairly satisfactory solution was found. If we wish to be acquainted with this solution, the only thing we would have to do, would be to look up such works as Bentham and Hooker’s “Genera Plantarum” and Engler and Prantl’s “Natürliche Pflanzenfamilien”. Some improvements might still be desirable, but these would be of minor importance only. These assumptions, however, are to be regarded as dangerous illusions. That the very serious nature of the shortcomings found in the delimitation and subdivision of these...
