Última A Critical Revision of the Genus Aristida being a preliminary study and an introduction to the monograph Naturalis Henrard, J.Th.. Being engaged during several years with a revision of the grasses preserved in the Rijks-Herbarium at the University of Leyden, my attention was called to the group of the Stipeae, and especially to the very difficult genus of Aristida. After an exhaustive study of the literature, I thought it desirable to have a monograph of this genus, containing extensive keys for the determination of all the species hitherto known, and I resolved to prepare such a work. It has been my good fortune that I had at my disposal not only the valuable collections of the Rijks-Herbarium, but that by the courtesy of the directors of the great herbaria in Europe and in America, I could study many thousands of specimens, among them authentic specimens and types. So several years... Tipo: Article / Letter to the editor Ano: 1926 URL: http://www.repository.naturalis.nl/record/508348 A monograph of the Genus Aristida Naturalis Henrard, J.Th..

Tipo: Article / Letter to the editor Ano: 1933 URL: http://www.repository.naturalis.nl/record/508331 A study in the genus Vulpia Naturalis Henrard, J.Th.. In conclusion, we propose the following nomenclatural alterations. For a good classification, the genus Vulpia is to be accepted as a member of the Festuceae. Various names of Vulpia are fixed according to our present rules of nomenclature, viz. V. bromoides (L.) GRAY, V. membranacea (L.) LINK, V. geniculata (L.) LINK, V. stipoides (L.) DUM. and V. Myurus (L.) GMELIN. For Vulpia ciliata the earliest valid epithet is taken and so this widely distributed species must bear the name of V. aetnensis TINEO, while its glabrous variety is named imberbis (Vis.) HENR.. Vulpia delicatula (LAG.) DUM. var. hirsuta HENR. and Vulpia geniculata (L.) LINK var. dasyantha HENR. are described as new varieties. Among the South American species the new combinations Vulpia...

Among the plants collected in the West-Indies by I. Boldingh during the years 1909 and 1910 there was a grass determined as Paspalum hemisphericum Poir., a name changed into glabrum. These determinations are incorrect because Paspalum hemisphericum Poiret is the same as the wellknown Paspalum paniculatum L. and also quite different from Poiret’s Paspalum glabrum, which, according to Mrs. A. Chase’s investigations, is the Paspalum laxum of Lamarck. Among Bolding’s plants there is a good specimen from the island of Bonaire, which, studied with Chase’s work on the North-American species of Paspalum, could not be identified. In Chase’s work also the species of Central-America and the West-Indian Islands are taken up, moreover the latter are also treated in... Tipo: Article / Letter to the editor Ano: 1943 URL: http://www.repository.naturalis.nl/record/525699 Identification of some Malaysian grasses Naturalis Henrard, J.Th.. When BUSE gave an enumeration of the grasses collected by JUNGHUHN in Java and Sumatra, he mentioned under Paspalum a species, described by RETZIUS in the year 1781 as Paspalum hirsutum. BUSE identified a grass from Sumatra as being the species of RETZIUS, on account of the description, having certainly not studied the authentic specimen, which was at that time not easy to consult. It may be that even the work of RETZIUS was not at his disposal, it is probable that he studied only the description, given afterwards in LAMARCK’S Encyclopédie. RETZIUS described his species from China, where it was collected by BLADH. Although the description of RETZIUS agrees fairly well with BUSE’S plant, we are in modern times not so satisfied with such an identification,... Tipo: Article / Letter to the editor Ano: 1935 URL: http://www.repository.naturalis.nl/record/524513 A Critical Revision of the Genus Aristida being a preliminary study and an introduction to the monograph Naturalis Henrard, J.Th.. A species with the habit of Aristida divaricata H. et B., but welldistinguished by the wanting column and the curious tuberculate lemmas. Closely allied to Aristida gentilis HENR., which differs however in the other position of the glumes and in the smooth lemma. The species resembles in some characters the Aristida Parishii HITCHC., the latter has however a totally different shape of the panicle and the lemma is not tuberculate-hispid, but scabrous only on the upper half. Among duplicates from the U. S. Nat. Herbarium, kindly received from Mrs. A. CHASE, I found a second plant belonging to the species, a plant also collected in Arizona, north slope of Santa Rita Mountains, leg. D. GRIFFITHS no. 7269.

Some years ago I treated a number of species of the genus Axonopus in Blumea IV, p. 510. Among them was Axonopus Fockei Henr., based upon Mez’s Paspalum Fockei, which was published in Fedde’s Repertorium XV, 1917, p. 62. I mentioned Ule’s number 8022 as identified by Mez himself being his Paspalum Fockei. Tipo: Article / Letter to the editor Ano: 1945 URL: http://www.repository.naturalis.nl/record/524788 On a new species of Piptochaetium from Uruguay Naturalis Henrard, J.Th.. Piptochaetium was described in the year 1830 by Presl as a monotypic genus; the only species was named and figured by him as Piptochaetium setifolium, an inhabitant of Peru. The genus has usually been included as a section in the genus Oryzopsis of Michaux, and various species were also published under the genus Stipa. In my monograph of the genus Aristida I had the opportunity to study the whole tribe of the Stipeae, and reasons are given there why Piptochaetium should be accepted-as a quite distinct genus. From the very good description given by Presl and from the accompanying plate, the genus is easily recognizable. In my monograph a key to the genera of the tribe of the Stipeae has been given. The genus Piptochaetium is limited to the new world. In...

Bot. Jahrb. XXX. [1901] p. 131. This species is very different from the true Digitaria adusta (NEES) GRISEB. and to distinguish by the flat, broad, glabrous leaves, the rather obtuse more turgid spikelets with a shorter pubescence and the shorter and whitish clavellate hairs, moreover also by the nearly equal length of glume II and III (the upper glume and sterile lemma). Digitaria adusta GRISEB. differs in the narrower, pungent, firm, convolute blades, hairy sheaths with velvety pubescent scales at the base of the plant, the spikelets are narrower, lanceolate and acutish, the upper glume in D. adusta is much shorter than the sterile lemma and both have longer fulvous hairs. Most allied to Digitaria... Tipo: Article / Letter to the editor Ano: 1930 URL: http://www.repository.naturalis.nl/record/508343 A monograph of the Genus Aristida Naturalis Henrard, J.Th.. In a preliminary work: „A critical Revision of the genus Aristida”, I have given a review of all the hitherto described species of this genus with the citation of the literature, the exact copies of the authentic descriptions and the figures of the spikelet-characters, taken from the type specimens so far as I could locate them. In many cases it was necessary to enter into critical observations, because the nomenclature and the ideas found in the different manuals are exceedingly entangled. The Revision, although very important for botanists who wish to know the exact data of a fixed species, is not to use if we wish to determine an arbitrary plant of our genus, therefore we must have a monograph and I indicated already that it was my intention to write...

The flora of the island of Java belongs, especially as to the family of the grasses, to the best explored ones. It was JUNGHUHN, who collected them extensively and his material was the basis of a fine enumeration by our countryman BUSE, in the year 1854. In modern times the grass flora of the island was thoroughly studied by Dr C. A. BACKER, who prepared not only very rich collections, but being familiar with the system of the Gramineae, gave in his ”Flora van Java“ a detailed study of this family with excellent descriptions and many very important data. Unfortunately his species-concept and his nomenclature is not always up to date and it is to be hoped that a new modern Flora of Java can be prepared on the basis of the very important and rich material...

Tipo: Article / Letter to the editor Ano: 1937 URL: http://www.repository.naturalis.nl/record/526379 Notes on the nomenclature of some grasses Naturalis Henrard, J.Th.. For the incorporation of various grasses in the herbaria of our institutes, we are constantly looking for the correct names to accept, according to the priority. The study of the existing names, as they are given in the Index Kewensis, is therefore indispensable. Working in various genera of the grasses we find, however, that many names are not tenable, because they were accepted without studying the whole literature of the subject. It appeared that, various names are omitted in the Index Kewensis, and indications given in various papers are sometimes neglected. Thus, the well-known and characteristic Aristida rhiniochloa HOCHST., already described in the year 1855 and treated by me in the Critical Revision (p. 510) and in my Monograph, is not yet given in... Tipo: Article / Letter to the editor Ano: 1940 URL: http://www.repository.naturalis.nl/record/525863 Notes on the genus Digitaria, with descriptions of new species Naturalis Henrard, J.Th.. Some years ago I had the opportunity to study more extensively a very interesting group of grasses, belonging to what is now accepted as a distinct genus, the genus Digitaria, formerly belonging as a subgenus to the genus Panicum. As to living plants of this group I was familiar with two european species, also found in the Netherlands. They are treated in the Synopsis of Ascherson nd Gräbner and once more in the second edition of this work. Under Panicum they bear the names P. lineare KROCKER and P. sanguinale L. The first species belongs to HACKEL’S „Ternata”, the name is invalid on account of the Panicum lineare of LINNAEUS, a species described from India, we know that KROCKER’s plant does not occur in India and it is therefore necessary to look for the...

ROXBURGH described in his Flora in the year 1820 a very curious annual grass and placed it in the genus Eleusine as E. verticillata ROXB.. This grass has spikelets which agree in many characters with those of the genus Eleusine, especially as to the rugose grain with a caducous pericarp, but differing from Eleusine in the up to 20-flowered spikelets and in the lemmas with a three-cuspidate summit. The many-flowered spikelets give the plant more the habit of an Eragrostis and under this genus a specimen was mentioned by WALLICH in his Catalogue. There are in the characters of the spikelets many other differences with the genus Eleusine and with Eragrostis. KUNTH and STEUDEL, indeed placed the plant under Leptochloa and there are still other opinions about...
