 leaves numerous, small, narrowly oblong, 1^3*="^ long, passing 

 into the small foliar bracts: nutlets similar, and all deeply 

 cupulate or hooded, the border of the hood thin and strongly

prickles, the tip of the nutlet with nearly an equal number of 

 slender prickles not involved in the border of the hood (these
