There are three Wright specimens of this species in the Grisebach Herbarium: 
Nos. ‘‘917=1548” and ‘'932=1548” from western Cuba, 1863, and no. 1549 from 
eastern Cuba, 1859. The type of C. brevigluma is in the Gray Herbarium with 
printed label for 1860-64, no. 1548. In Sauvalle’s Flora Cubana the type is mis- 
printed ‘‘1848 p. p.’’ Wright seems to have distinguished his species from C. eleu- 
sinoides mounted on the same sheet (Wright 1549), which he regarded as the true 
C. cruciata. Wright’s type matches his no. 1549 in the National Herbarium. 
3. Chloris elegans H. B. K. Nov. Gen. & Sp. 1: 166. 1816.

The type of this has not been examined, but the specimens cited above agree 
well with the plate accompanying the original description.@

Hitchcock in 1906; Cienfuegos, Combs 631 in Gray Herbarium. 
The Grisebach specimen is from eastern Cuba, 1859, no. 1548. Nos. 1548 and . 
1549, in the Engelmann Herbarium, both from eastern Cuba, 1860, are Chloris 
cleusinoides. No. 1549 in the Gray Herbarium is also this species (Monte Verde, 
eastern Cuba in 1859). 
Combs’s 631, from Cienfuegos, in the Gray Herbarium is the type of C. eleusinoides 
variety vestita. It differs from Grisebach’s type in being somewhat more pubescent.
