Chase — Notes on Genera of Panieea. IV. 139 



two are species of Paspalum in which both glumes are wanting, the third 

 has characters sufficiently distinct to be referred to a different genus. 

 (See Reimarochloa Hitchc, of which R. acuta is the type.) Since the 

 three species cited belong to two genera, it is necessary that the name 

 Reimaria go with the larger group. (See Hitchcock, Contr. Nat. Herb. 

 12 : 198. 1909. ) Of these two species we take the first as the type species. 

 This was described from a plant collected " Prope Pnanbo in America 

 meridionali. Humboldt et Bonpland." Fliigge gives "Humboldt et 

 Bonpland " as the authors of the species. Kunth later (Mem. Mus. Par. 

 2 : 68. 1815) transferred the specific name to Paspalum. A part of the 

 type or a duplicate of it marked "ex Hb. Kunth & Hb. Humb." was 

 examined in the Berlin Herbarium. It is the species distributed as Pas- 

 palum candidum H. B. K. by John Donnell Smith and by the Herb. 

 Instit. physico-geogr. nat. costaricensis, and represented in the National 

 Herbarium by John Donnell Smith 4992, Tonduz 8-492 and several others 

 collections from Costa Rica and Guatemala. Doell (Mart. Fl. Bras. 2 2 : 

 39. 1877) proposes a section Eremaehyrion for the species of Paspalum in 

 which both glumes are wanting. 



Paspalanthium Desv. Opusc. 59. 1831. This genus, which is differen- 

 tiated from Paspalum by the loose glume and sterile lemma exceeding 

 the fruit and by the membranaceous rachis, includes a single species P. 

 stoloniferum Desv., based on Paspalum stoloniferum Bosc. (Trans. Linn. 

 Soc. 2 : S3, pi. Hi. 1794 " H. in Perua"). The type specimen was 

 examined in the Bosc Herbarium at Padua. It is the species frequently 

 cultivated under this name, with thin, conspicuously rugose sterile 

 lemma. 



Moenchia Wender in Steud. Nom. Bot. ed. 2. 2 : 153. 1841, not Roth. 

 1788. There is no description and a single nomen nudum, M. speciosa 

 Wender, is given as a synonym of Panicum sacrltaroides Kunth, upon 

 which is based Paspalum saccharoides Nees. 



Anachyris Xees, in Hook. Kew Journ. 2 : 103. 1850. A single species, 

 A. paspaloides Nees "In Brasilia. Gardner, n. 4031 in herb. Lindl.," 

 is included. A portion of a raceme from the type specimen was kindly 

 sent by the herbarium at the University of Cambridge for deposit in the 

 National Herbarium. The species is of that small group including 

 Paspalum malacophyllum Trin. and P. elongatum Griseb., in which both 

 glumes are wanting and in which the very convex fertile lemma is longi- 

 tudinally grooved. This accounts for the mistake made by Nees in 

 placing the proposed genus in Oryzeae. In this group the fruit is rather 

 readily detached from the spikelet leaving the thin sterile lemma attached 

 to the rachis. It must have been such a fruit, mistaken for the entire 

 spikelet, that Nees had before him when he described the genus. 



Steudel (Syn. PI. Glum. 1 : 33. 1854) spells this name Anachyrium. 



Maizilla Schlecht. Bot. Zeit. 8 : 601, 605. 1850. A single species is 

 given, " M. stolonij 'era Bosc. sub Paspalo." 



Cymatochloa Schlecht. Bot. Zeit. 12 : 817, 821. 1854. Two species, 

 " C.fluitans N[o]b. (Ceresia fluitans Ell. * * *) " and " C. repens
