90 MONOECIA— TRIANDRIA. Carex. 



grass green ; the spikes paler than the last, and rather white, 

 orgreyish, in everystage of their growth. Stems 1 2 or 18 inches 

 high, weak, and partly reclining, with 3 acute rough angles. 

 Leaves sheathing the bottom of the stem, and usually rising 

 above its summit, rough at the edges and keel. Spike when in 

 flower an inch, or inch and half, long, of from 6 to 10, or more, 

 sessile, erect, ovate, acute spikelets, each subtended by an ovate, 

 concave, close, membranous bractea, with a green taper point 

 and keel, 2 or 3 of the lowermost bracteas being often length- 

 ened out into an extremely slender, rough, capillary appendage. 

 The spikelets are rarely in pairs ; the lowermost of all sometimes 

 compound. Each consists of several harrenjloretsj with about 

 as many fertile ones below them. As the latter ripen seed, the 

 spikelets become roundish, or hemispherical, 3 or 4 of the lower 

 ones being widely separated from each other. Scales ovate, or 

 lanceolate, membranous, hardly so long as the /rwi/, which is 

 broadly ovate, externally convex, flat or concave within, mode- 

 rately spreading, not re'flexed, pale, with a thick green margin, 

 very smooth in every part, except a slight roughness near the 

 cloven point of the beak, of ten scarcely perceptible. Stam. 3.

jS is rather an accident than a variety, having a division, or branch, 

 at the bottom of the spike, which perhaps Micheli alone has met 

 with. 



The figure in Engl Bot. is very incomplete, as wanting i\\e fruit, 

 which in its ripening state clearly distinguishes this species from 

 the last. Dr. Wahlenberg unites them, having apparently never 

 seen C. divulsa, which though well known to English botanists, 

 is rare on the continent. Specimens are in the Linnaean her- 

 barium, without any place of growth or name, and I have some 

 from Switzerland. Dr. Hooker follows Wahlenberg. Having 

 carefully examined the question, I am satisfied, even without an 

 appeal to the great names of Ray, Micheli, Hudson, and Good- 

 enough.
