Caricographu. 6 1 



small, distinctly three nerved, very compact, and much di- 

 verging in maturity ; pistillate scale ovate, somewhat 

 ovate-lanceolate, awned,tawney with a green keel, shorter 

 than the fruit, and its awn often projecting a little beyond 

 the fruit. 



Flowers in May — grows in moist meadows. 



This is a variable species. The common variety is ex- 

 cellently figured by Schk., who has given three different 

 forms of the fruit. There is much difference also in the 

 magnitude and aggregation of the spikelets. I have never 

 seen one specimen, however, whose spike would corres- 

 pond to the character given by Pursh to this species : 

 "spicis anguste paniculatis," — the spike is not a /)amc/e, 

 and very rarely is supra-decompound. The fruit is much 

 less compressed and less acuminate on some specimens. 

 It would seem that a specimen of this kind was described 

 by Wahl. under the name of C. microsperma in the fol- 

 lowing terms. 



" Spiculis apice masculis in clavam supradecompositam 

 crassiusculam conglomeratis, squamis cuspidatis, capsulis 

 minutis ventricoso-ovalibus acuminato-subrostratis acutis- 

 angulis subdivergentibus ; foliis angustis." 



25. C. setacea. (Mihi.) 



Spicis sessilibus alternis approximatis bracteatis ; spiculis 

 apice masculis ovatis obtusis conglomeratis bracteatis ; 

 fructibus ovato-lanceolatis acuminatis corapressis bifidis 

 subdivergentibus, squama ovato-lanceolata aristata sub- 

 jequalibus. 



This new species has probably been confounded with 

 C. multiflora. In its general appearance and in several 

 characters it is very different from it, and from any species 

 hitherto described. It appears to be intermediate between 

 C. multiflora and C. stipata : its culm and leaves much 

 resemble the latter, as welt as its fruic, except that it is 

 much more compressed, and its decompound spike and 

 aggregation of spikelets are much like those of ihe former. 

 Its fruit however is less ovate, longer and more compress- 

 ed than that of C. multiflora. Its general characters are 

 the following.
