HITCHCOCK—GRASSES OF CUBA. 229 
There are four specimens of this in the Grisebach Herbarium: No. 750 labeled 
‘Prope villam Monte Verde dictam. Cuba orientali;”’ another numbered 750 from 
eastern Cuba, 1856-57; a Wright. specimen without number or locality collected in 
1860-64; and a specimen with proliferous spikelets, numbered 887, ‘‘Cuba occ. Wr. 
1863.’? This species not infrequently occurs with proliferous spikelets, as in Palmer 
“& Riley 130 cited above. The spikelets then consist of many sterile lemmas and 
the plants appear as if belonging to the tribe Festuceae. 
4. Ichnanthus wrightii sp. nov. . 
Culms slender, prostrate-spreading, more or less rooting at the nodes, glabrous 
or sparsely villous, 20 to 30 cm. long; sheaths mostly less than half the length of 
the internodes, striate-nerved, villous on the margins, otherwise glabrous or nearly 
so; blades ovate-lanceolate, striate-nerved, faintly 3 to 5-ribbed, glabrous, 12 to 
30 mm. long, 2 to 8 mm. wide on the sterile shoots, somewhat larger and thicker 
on the ascending flowering culms, all abruptly or cordately narrowed into a slender 
stalk | to 5 mm. long on the fertile culms, or as much as 15 mm. long on the sterile 
shoots; panicles 4 to 8 cm. long, consisting of a few spike-like racemes, 0.5 to 2 cm. 
long; spikelets 3 mm. long, glabrous, the pedicel minutely pubescent; lower glume 
about half the length of the spikelet, 3-nerved; second glume and sterile lemma 
equal, acuminate, strongly 5-nerved; fertile lemma scarcely 2 mm. long, the edges 
meeting and covering the palea, except at the very base, the outer margin of the 
base of the lemma bearing a scar at each side, but no wings. 
Wright’s 3880. U.S. National Herbarium no. 559959 of this collection is the type. 
The specimen in the Sauvalle Herbarium is labeled, ‘‘Under overhanging rocks 
(damp) and around base of palms beside the Rio Seco in Arroyo Honda, Pinar del 
Rio, Dec.’? The Grisebach specimen consists of a single spikelet in a packet, labeled 
“Echinolaena Sp.’’ no. 760. In the Kew Herbarium there are four specimens num- 
bered 2, 23, 244, 760. Nos. 760 and 3880 are also in the Gray Herbarium. This 
species is allied to 7. mayarensis.

Herbarium. In the herbarium of the New York Botanical Garden are the follow- 
ing: Matanzas, Britton & Shafer 221; Santiago de Cuba, Taylor 422, 481. 
Wright’s numbers 751 and 1543 in the Grisebach Herbarium are from eastern Cuba, 
1859. The latter is numbered 1593 in Sauvalle’s Flora Cubana. 
It is quite possible that the specimens here included may be referred to distinct 
species. The type of Panicwm setaritum Lam. at Paris resembles Wright’s 1543. The 
blades are short and the clusters of spikelets globose and few-flowered. Wright 751 
and Curtiss 268 and 593 have larger and longer blades and spikes, but some of the 
other specimens are intermediate.
