In its pilose glumes unique in the maze of plants which pass undis- 

 tinguished as Trisctum spicatum. In its comparatively small spike- 

 lets and interrupted inflorescence somewhat intermediate between 

 the more arctic-alpine T. sjjicatum, var. Maidcnii (Gandoger) 1 and 

 T. spicatum, var. mollc (Michx.) Piper. 



True Trisctum spicatum of Europe, based upon Aira spicata L. Sp. 

 PI. i. 04 (1753), is apparently not found in northeastern America, 

 though some Arctic and northwestern specimens may belong to it. 

 The alpine plant of Europe, as shown by many specimens and descrip- 

 tions as well as by such plates as those of Hallier, 2 Hartinger 3 or Cor- 

 revon, 4 is a low plant (0.5-2 dm. high), with sheaths and leaf-blades 

 either pubescent or glabrous; the inflorescence cylindric to obovoid, 

 violet, bronze or brownish, very dense and spike-like, 1.5-3 cm. long,
