206 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
29. Paspalum rupestre Trin. Linnaea 10: 293. 1836. 
Wright 3444, 3445; near Habana, /Zitehcock in 1906; Leon 286. 
The Grisebach specimen is from eastern Cuba, 1860, numbered “ 109:=3445,”’ and 
is labeled, “Paspalum lindenianum Rich. (Megaphyllum Steud.).? under whieh 
name it is listed in Grisebach’s Catalogue of Cuban Plants.@ A second specimen is 
from western Cuba, 1863, and is numbered ‘939=3445."’ A third specimen collected 
in 1863 and numbered ‘943=3444,”’ is included by Grisebach in his cover of P. caes- 
pilosum. Wright’s 3445 in the Gray Herbarium is labeled ‘‘Pinales near Baracoa, 
June 15.”

The characters which separate this from P’. distichum 1.., the glabrous spikelets and 
more or less suppressed midnerve of the glume, may prove to be inconstant, Grise- 
bach’s specimen from western Cuba, 1863, numbered 947, is this species. A part of 
Wright 1546 (1546a) in the Torrey Herbarium has ¢labrous spikelets, and consequently 
would be referred to P?. vaginatum. 
Lagasca’s type, labeled ‘ Digitaria foliosa sp. nu. ex Havana, Boldo iter,’ is in the 
herbarium of the Botanical Garden at Madrid.

Grisebach’s specimen is numbered 302 (labeled  stramineum), while the specimen 
in the Sauvalle Herbarium bears this number in addition to no. 3446. The type speci- 
men of P. leucocheilum Wright is in the Gray Herbarium. The spikelets are somewhat 
smaller than normal (2 mm. long), and the inflorescence consists of a single spike 
partially concealed in the uppermost sheath. The spikelets have the shape and 
pubescence of P. virgatum.

This differs from P. virgatum in its scarcely pilose rachis and oblong-obovate, acute, 
glabrous spikelets. [t appears to be a distinct species, but as the type has not been 
examined, our plants are referred as above, rather than separated under a new name. 
This form appears to be included in P. virgatum glabriusentum by Doell in Mar- 
tius’s Flora Brasiliensis.®> Wright’s 3446 in Gray Herbarium is labeled, ‘In large 
tufts on sand bars of the Baracoa near N. Sophie, Sept. 11.” ,

This specimen in the Sauvalle Herbarium is too fragmentary to identify. It 
appears to belong to none of the species enumerated in the list. It is listed in Sau-
