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... |

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... |

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... |

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... |

The genus Mussaendopsis was created by Baillon in 1879 for a tree found by Beccari in Sarawak, Borneo. As it appeared afterwards, the same species occurs also in the Malay Peninsula, on the islands between the latter and Borneo, and in Sumatra. On specimens collected in the Malay Peninsula, in 1884 the genus Creaghia Scort. was founded. The descriptions of the two genera are very similar, and as Mussaendopsis Baill. is not mentioned by Scortechini, we may safely assume that Baillon’s publication was unknown to him. The identity of the two genera was disclosed by K. Schumann in his monograph of the family in Engler & Prantl. Subsequently the plant was dealt with by Stapf, King and Gamble, Ridley and Lemée. None of the descriptions, however, is entirely... |

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... |

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... |

The genus Praravinia was created by KORTHALS (in TEMMINCK, Verhand. Nat. Gesch. Ned. Overz. Bezitt., Bot., p. 189, tab. 41, 1839-1842) for a plant which he had collected in the south-eastern part of Borneo. He described it as similar in habit and doubtless nearly related to Urophyllum WALL. His diagnosis of the genus, however, does not substantiate this point of view, for it contains two statements which seem to exclude the possibility of a near affinity: the aestivation of the corolla lobes is described as imbricate, whereas in Urophyllum and its allies it is always valvate, and the number of corolla lobes is said to be half as large as that of the stamens, a condition unknown not only in Urophyllum but in the whole family. As in the description of the... |

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... |

Among the Acanthaceae grown in the glasshouses of the University Botanic Garden, Utrecht, a plant labelled Aphelandra velutina drew my attention, first, because it obviously belonged to an entirely different genus, and secondly, because a description under this name could nowhere be found. The coincidence of these two grounds for bewilderment might be explained by assuming that Aphelandra was merely a perversion, probably caused by the inadvertency of a transcriber, of the true generic name. This sounded plausible enough, but the name itself could not be found, for all attempts to refer the plant to one of the existing genera failed. It looked as if the plant might have been described somewhere, but for the time being there was no indication at all as to... |

Among the most aberrant types of pollen grains found in plants which have been referred to the family Acanthaceae, are those of the genera Meyenia N. ab E. and Thomandersia Baill. Although the pollen grains were described by LINDAU under different names, those of the first genus as cogwheel-shaped and those of the latter as lenticular, they are really very similar: in both genera they are depressed globose, provided with five or more meridional grooves extending from the equator to about halfway the poles, and without clearly circumscribed germ pores. The difference between the two kinds of grains lies in the presence or absence of ribs: in Meyenia the grooves are borne on the top of ribs separated from each other by shallow depressions, whereas in... |

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... |

AUBLET described and figured in his “Histoire des Plantes de la Guiane Francoise” (Vol. I p. 170-172 and Vol. III t. 65, 1775) under the name Simira tinctoria a tree belonging to the family Rubiaceae which until very recently was represented in the herbaria solely by specimens that he himself had collected. One of these specimens is preserved in the herbarium of the British Museum (Natural History) and another one in the “Herbier Denaiffe” (cf. LANJOUW, J. and H. UITTIEN in Rec. d. trav. bot. Néerl. 37, 357, 1940), which was recently acquired by the Museum d’Histoire Naturelle, Paris. AUBLET’s new genera were viewed in his own time and even long afterwards with considerable distrust, and when we see that their separation from older and already well-known... |

Recently I got the opportunity of examining a specimen from the “Rijksherbarium”, Leiden, which was provided with a label on which ROTH had written in the middle the name of the plant, viz. “ Micranthus serpyllifol-Roth ” and in the lower right corner the name of the collector, viz. “Heyne”; in the lower left comer another hand had added “Ind. or. Hb. Roth”. As the specimen proved to answer the description of Micranthus serpyllifolius given on p. 282 of ROTH’s “Novae Plantarum Species, Halberstadt 1821,” there can be little doubt that it is either the type of this species or else a duplicate of the latter. This is the more important as none of the authors who in the past ventured an opinion with regard to the taxonomic position of ROTH’s species,... |

In my “Notes on the Acanthaceae of Java” (in Verh. Kon. Ned. Akad. v. Wetensch., Afd. Natuurk. 2nd Sect. 45, 2: 29,1948) I discussed the three epithets that had been applied to Rumph’s “Folium tinctorum” after the latter had been transferred to the genus Peristrophe, which, as is well known, was based on this species. Nees, the author of the genus, has used the name P. tinctoria, because he regarded Justicia tinctoria Roxb. as the oldest binomial that had been applied to it. This was contested both by Merrill and by Hochreutiner. Merrill was of opinion that Justicia bivalvis L (1759) was its oldest name, but as I pointed out l.c. this binomial must be regarded as a “nomen confusum”; the description indicates a Dicliptera species, whereas the plate in the... |

It can hardly be denied that the expression “General Plant Morphology”, which is so often met with in botanical textbooks, has little or no meaning. A general morphology of the Plant Kingdom would have to occupy itself with those morphological features that are common to all groups of plants, which means that it would have to confine itself to the common features of the cell structure and eventually to such peculiarities as are independent of the uni- or pluricellular structure of the plant body, e.g. its enclosure within a rigid envelop. However, when we realize that there is in this respect no fundamental difference between the common features of plants and animals or, at least, of some groups of animals it will be clear that the use of the expression... |

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... |

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.
