44. APZiUDA, Linn. 



■ 



A leafy pereDnial grass. Stems geniculately ascending from a creeping 

 or decumbeut base, sometimes scandent, panicnlately branched. Leaves 

 petioled, flat ; sheaths of upper spathiform. Inflorescence of very many 

 solitary small simple spikes, terminating the stem and branches, each 

 enclosed in a special membranous peduncled spathe, together forming a 

 leafy panicle. Spikes of one linear joint gibbously bulbous at the basf», 

 and jointed on the peduncle at the base of the spathe by a minute 

 curved pedicel; rachis (joint) smooth. Spikelets 3, a sessile 2-fld. bisexual 

 with a pedicelled imperfect (reduced to a small gl.) at the base ^f^^^ 

 rachis, and a terminal male or neuter, rarely bisexual; sessile spikeles 

 seated on the bulbous base of the rachis (callus of authors) ; gls. 4, 1 cbar- 

 taceous conyolute many -nerved margins not inflexed, II compressed &-'' 

 nerved dorsally gibbons keeled, III ovate-lanceolate hyaline male paleate, 

 lY much smaller bisexual ovate paleate entire or 2-toothed, awned or not. 

 Lodirules 2, cuneate. Stamens 3, anthers short. Styles free. Gratn 

 oblong, embryo large. 



In the above description I consider what Hackel describes as the pedicel of t e 

 upper spikelet to be the rachis of the uninodal spike; and his callus of tbese&sie 

 spikelet to be a bulbous inflation of the base of the rachis.
