This form connects T. dactyloides with T. lanceolatum. In some 
specimens the upper spikelet of the staminate pair is somewhat pedicelled. 
T. dactyloides and possibly some of the other species may occur widely 
distributed in South America. Information on this point is desired. 
TRIPSACUM FLORIDANUM Porter, Contr. Nat. Herb. 3:6. 1892. 
PortTEr’s herbarium name was published by Dr. VAsry in his monograph 
of the grasses of North America. Type locality ‘Florida (A. P. Garber) 
and Texas (G. C. Nealley);’ duplicate type in National Herbarium. 
T. dactyloides floridanum Beal, Grasses 2:19. 1896. There are no 
_ specimens of this species from Texas in the National Herbarium, nor 
are there any so labeled by Dr. VAsEy; consequently the Texas locality 
given above is uncertain and is probably incorrect. 
Our specimens are all from the vicinity of Miami, Florida, Garber 454, 
June 1877 (type); Pollard & Collins 272, April 1898; Eaton 530, Dec. 
1903; Hitchcock, March 1903. 
Distinguished from T. dactyloides by its smaller size and much nar- 
rower leaves. 
TRIPSACUM FASCICULATUM Trin.; Ascherson, Bot. Zeit. 35:521- 
1877.—Well distinguished by its ample glabrous leaves, which are as 
much as 6.5°™ wide and 70% long, resembling leaves of Indian corn 
(Zea mays L.). Plant glabrous throughout; spikes branched, forming a 
fascicle; staminate portion slender and more or less flexuous, the spike- 
lets 5 to 6 ™™ long and broadest near the top. 
The name first appears in the second edition of SrEUDEL’s Nomen- 
clator. 2:712, as Tripsacum “‘fasciculatum Trin. Mpt. Mexico. T. 
dactyloides Schlecht. in Linnaea VI.”” The latter name is a nomen nudum, 
as is also T. fasciculatum Trin. in Steud. Gram. 1:363, and in Ruprecht, 
‘Bull. Acad. Brux. 9:243. The first description appears to be by ASCHER- 
SON’ in 1877, Bot. Zeit. 35:525, where a specimen from ‘“‘Pr. Hacienda 
de la Laguna (Schiede)”’ is designated as the type. Fournter, Mex. 
Gram. 69. 1881, includes the name without description and cites the - 
following specimens: Hacienda de la Laguna (Schiede 947); Orizaba 
* ASCHERSON had previously mentioned the species and given a brief description 
as follows: ‘Diese Art besitzt Blatter von der Breite der Maisblitter, und die zahl- 
reichen, schlaffen, mannlichen Inflorescenzzweige, deren Aehrchen kleiner als bei 
T. dactyloides sind, erinnern ebenfalls an Euchlaena.” (Verh. bot. Ver. Pr. Brandenb. 
17:79. 1875, in a footnote to an article on Euchlaena mexicana.)
