| 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... |

| 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... |

| 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... |

| 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... |

| During the preparation of an account of the grasses for the flora of Dutch Guiana many difficulties were found in the identification of species of the genus Axonopus. Our knowledge as to the most recent treatment is entirely based upon Doell’s work for the Flora Brasiliensis. It is, however, evident that Doell did not see many types and his concept of many species proves to be incorrect. The modern genus Axonopus is not accepted by Doell but treated by him as a section Emprosthion of the large genus Paspalum. The difficulties arose already when he treated Fluegge’s Paspalum furcatum which is a continental North American species. Raddi’s Paspalum obtusifolium from Brazil, although given as a synonym, is a quite distinct species. As another synonym is... |

| Among the grasses, preserved at the Rijksherbarium, one of the most valuable collections is certainly that of the well-known agrostologist and collector, B. BALANSA. It contains not only the types of the grasses, described by himself, but also very beautiful material, received by him from his contemporaries. All his European and Oriental grasses, those collected by him in New Caledonia, Tonkin and Java, besides a rich material from his travels in Paraguay and Argentina, are represented in this collection together with a beautiful set of ARECHAVALETA’s grasses form Uruguay. The material is in extraordinarily good condition and was very completely collected by him. I could already describe many novelties from this collection. One of these is particularly... |
