_ A gregarious shrub 8-12 ft. high, very closely allied to A. spatMflora, of which 

 it is the Eastern representative, distinguished from that species in having broader 

 bracts enclosing more spikelets, shorter leaves, a hairy callus below the longer petiole, 

 longer macros of the fig. gls. and a long more ' acuminate palea. It is readily 

 recognized by its yellow stems and reddisli branchlets. The stems are leafing only, 

 or flowering only, or both.
