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...

On the geographical distribution of the genus Acrachne

Ano: 1939

URL: http://www.repository.naturalis.nl/record/526186

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...

Identification of some Malaysian grasses

URL: http://www.repository.naturalis.nl/record/508356

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,...

New or insufficiently known species and new binomials in the genus Digitaria

= Panicum adustum NEES var. mattogrossense PILG. in Engl. 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...

Notes on the nomenclature of some grasses

Ano: 1930

URL: http://www.repository.naturalis.nl/record/508343

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...

A monograph of the Genus Aristida

Ano: 1936

URL: http://www.repository.naturalis.nl/record/525085

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...

On a new species of Paspalum from the island of Bonaire

Ano: 1929

URL: http://www.repository.naturalis.nl/record/508320

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...

A study in the genus Vulpia

Ano: 1943

URL: http://www.repository.naturalis.nl/record/525699

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...
