CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



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.

133. Panicum Occident ale Scribn. 



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 a 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."
