The above description applies especially to P. barbata. This genus 

 and Coix are amongst the most complicate in the disposition and structure 

 of the spikelets of any amongst grasses.

Stem 3-6 ft., as thick as the little finger below, terete, 

 smooth, longer internodes up to 10 in., nodes narrowly softly- 

 bearded ; 1. up to 10 by \\ in., linear, acuminate, scabrid 

 above, less so or smooth beneath, sometimes hirsute, midrib 

 stout, veins many, slender, base narrow, margin scabrid, sheath 

 long, smooth, glabrous or hairy, ligule tomentose; ped. of

 spathiform sheaths 1 in. or more, tip awned, awn sometimes an 

 in. long; proper spathes J in., oblong, awned; male portion of 

 raceme appearing as if sessile on the top of the fem. spikelet, 

 articulate with the internode below it, which is embraced by the 

 margins of the outer glume of the fem. spikelet, rhachis hardly 

 articulate between the male spikelets, which are \-\ in. long ; 

 glume I of male spikelet oblong or lanceolate, obtuse acute 

 or apiculate, glabrous or hairy, veins more or less trabeculate ; 

 glume I of fem. spikelet intruded at the base to receive the 

 clavate end of the lower internode of the rhachis of the spike, 

 quadrately oblong, sides rounded, lateral veins of glumes II 

 and III arching at their tips to meet the mid vein.

Erect, annual or perennial grasses ; infl. of solitary,

 laterally strongly compressed, i-fld., bisexual, callus short or 

 long, bearded; glumes 4, I and II usually divaricate in 

 flower, empty, I coriaceous, linear, sides complicate, dorsally 

 rounded, II as long as I or longer, chartaceous, empty, oblong, 

 margins hyaline, sides complicate, dorsally keeled, keel some-
