inch or less long) ; perigyniwm long-pointed and but slightly 

 curved, triquetrous, finely many nerved, much longer and 

 broader than the acute or muticous very thin scale, Carolina 

 and southward, and westward to Texas. 



Var. DIVARICATA. 



Differs from the type in its larger and more or less clavate 

 and peduncled staminate spike, the long and large (an inch or 

 more long) pistillate spikes, which are scattered, the lower ones 

 being remote and very long-peduncled, and particularly by the 

 very large and divaricate trigonous and long-pointed perigynium 

 which is contracted into a stipe-like base half or more as long as 

 the body. Plant tall ; leaves rather narrow ; bracts moderately 

 broad, three to five inches long. Near Washington, D. C, Vasey, 



The following names belong to C. laxiflora : 



C. trnncata, Boeckl, Flora, 1858, 649, v. s, Hb. Carey, and 



Hb. Kew. (Drummond's 423), = C. laxiflo'a. 

 The scales are white-hyaline, truncate and awned, but I find 

 no other characters to separate this from ordinary forms of the 

 species. The characters of the scales are variable in this plant. 

 I have the same plant from Louisiana. 



C. btilbosa, Boeckl, Flora, 1855, 597, v. s. Hb. Kew., is the var. 

 Michaiixii. The species was described upon an unnum- 

 bered specimen collected by Drummond. The specimen 

 in Hb. Kew., although unnamed, answers so completely the 

 description that I have no hesitation in taking it for a du- 

 hcate of Bceckeler's original ; it is from Drummond. In 

 his later writings, Boeckeler has not mentioned this species.
