The type of this plant, as indicated in A. Gray, Gram. & Cyp., 
is the form with long and narrow spikelets, the scales narrow and 
acuminate. Dr. Vasey took up and named as S. vaginacflorus the 
form with shorter and broad spikelets, the scales merely acute. 
This plant is considered below. 
SPOROBOLUS NEGLECTUS nom. nov. 
Sporobolus vaginacflorus Vasey, Wats. & Coult. in A. Gray, 
Man. Ed. 6, 645. 1890. Not Wood. 1861. 
This is the plant that has long passed as Vilfa vaginaefiora 
Torr., but it is not the same, as indicated under the preceding 
species. Owing to this mistaken identity this plant appears to be 
. without a name, and so the one given above is proposed. The 
broader and shorter spikelets, with the scales broad and merely 
acute, will readily separate this plant from the S. vaginacflorus 
Wood. 
In the vicinity of New York it is much less common than S. 
vaginacflorus, which grows plentifully in many localities. 
Dry sandy soil, Massachusetts to Kentucky, Tennessee and

SPOROBOLUS BREVIFOLIUS (Nutt.) Scribn. Mem, Torr. Bot. Club. 
5: 39. Inpart. 1894. 
Agrostis brevifolia Nutt. Gen. 1: 44. 1818. 
There seems to be much confusion in regard to Sporobolus de- 
pauperatus and S. cuspidatus. Forms of what appears to be a 
good species have been variously referred to either of the above. 
They agree well with the description of Agrostis brevifolia Nutt., 
and they are here referred to that species. The leaves are short, 
-1/-2' long; the empty scales obtuse or merely abruptly acute, less 
than one-half as long as the acuminate and sometimes short-cuspi- 
date flowering scale.
