second glume scarcely equaling the fruit at maturity; fruit 1.5 mm. long, 0.8 mm. 
wide, elliptic, obtuse. 
Autumnal form widely spreading, sparingly branching from the lower nodes, the 
leaves and panicles not greatly reduced, the panicles overtopped by the leaves, 
these less copiously pilose. 
This species may be distinguished from P. implicatum and P. meridionale by the 
larger spikelets, the long-exserted panicles, the aggregation of the leaves toward the 
base of the vernal culms, and the sparingly branched, almost prostrate autumnal 
form. In its most characteristic form the panicle branches are strictly ascending at _ 
maturity and spikelet-bearing near the ends only, thus forming a compact panicle 
with a long naked base.

Panicum occidentale Scribn. Rep. Mo. Bot. Gard. 10:48. 1899. Based on “P. 
pubescens [Lam. misapplied by] Presl, not Lam. nor Michx.’’ While the type must 
be the specimen in Presl’s herbarium, Scribner's conclusions were based on a dupli- 
cate in the Bernhardi Herbarium at the Missouri Botanical Garden, labeled in Presl’s 
handwriting ‘“‘ Panicum pubescens Michx.’’ The type specimen collected by Haenke, 
which is the basis of Presl’s « identification, is in the Bohemian Museum at Prague 
and consists of three culms with mature primary panicles, and with secondary panicles 
on short branches from the lower nodes, that is, vernal culms showing the commence- 
ment of the autumnal form. One label reads “‘ Panicum pubescens Michx.;’’ another 
bears the locality ‘“‘Archipel,” which refers to the vicinity of Nootka Sound, Van- 
couver Island, the locality as published by Presl, ‘‘Hab. in Nootka-Sund.”’
