On a new species of Paspalum from the island of Bonaire

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 Hitchcock’s posthumous work on the grasses of that region.
