Paspalum Leoninum Chase, sp. nov.—A low tufted perennial, with 
narrow leaves mostly crowded at the base, slender nearly naked 
_ culms and solitary usually purplish racemes. Culms 15~35 cm. 
high, very slender, wiry, compressed, ascending or spreading and 
more or less sinuous, glabrous, the nodes ascending-pubescent; lower 
sheaths overlapping and keeled, glabrous or sparsely pubescent 
on the scarious margin and with a few stiff hairs on the auricles, 
usually but a single leaf about midway on the culm, the sheath 
with a few scattered long hairs or glabrous; ligule membranaceous, 
about o.5 mm. long; blades flat or somewhat involute from a folded 
base narrower than the summit of the sheath, 3-7 cm. long, 1-2 
mm. wide, more or less curled, glabrous on both surfaces or minutely 
puberulent on the upper, a few stiff hairs on the margin and rarely 
on the upper surface, the blade of the uppermost leaf reduced to a 
mere tip; raceme 2~-3.5 cm. long, slightly curved, a few long hairs 
at the base; spikelets solitary, on very short, flattened, scabrous 
pedicels, closely imbricated, almost concavo-convex, 1.3-1.5 mm. 
long, about o. 7 mm. wide, oval, glabrous; second glume 3-nerved, 
the sterile lemma with a nerve near either margin, the midnerve 
Suppressed or apparent only at the summit; fruit nearly as large 
as the spikelet. 
Type U.S. National Herbarium no. 618,754; collected August 30, 1909, on 
“Obispo hill, near Sancti Spiritus,’ by Brother Leén (no. 950). 
This species is most nearly related to Paspalum rupestre Trin., from single- 
Spiked specimens of which it may be distinguished by the more delicate culms 
and the more closely imbricated, glabrous spikelets, the second glume with 
the midnerve suppressed. 
Paspalum Leoninum is named in honor of Brother LEON, of the Colegio 
de la Salle, Vedado, Habana, whose collections have added greatly to our 
knowledge of the grasses of Cuba. 
A second collection of this species was made on the Jata Hills, Guanabacoa, 
September 12, 1909, Leén 9409.
