long, 3/’-4’’ in diameter, all filiform-stalked and nod- 
ding or the upper one nearly sessile; perigynia broadly 
oval, spreading, smooth, slightly inflated, pale, 
strongly 1-nerved on each side, the body about 1// 
long, contracted into a very slender beak of nearly 
twice its length; scales lanceolate, spreading, long-
