MACLOSKIE I REVISION OF FLORA PATAGONICA. 77 



C. GAYANA Desv. Macl., p. 282 (in Section Divisae). 



Lower sheaths brown. Unisexual. Utricles 2 mm. long, orbiculate- 

 ovate, short rostrum. 



Though very much akin to, it is not, as Macloskie states, identical with 

 C. dimsa Huds. and does not occur in Europe or Western Asia. It is 

 met with in N. America, Fuegia and in Patagonia, especially, in the 

 western parts of its steppe region and in the mountains up to an altitude 

 of at least 900 m.; also in Argentina and Chili. D. 



P. 282: C. GAYANA Desv. has var. schedonautos (Steud.) Kiik. 



Culm 1-2 feet, firmer. Spikelets crowded, in a compound spike inter- 

 rupted at the base, 3 cm. long. Magellan, Oazy Harbor: Fuegia; N. 

 Patag., territory of Neuquen. 



C. GAYANA Desv. var. DENSA Kiikenth. 



Spikelets more numerous, densely crowded, nearly all males, rarely a 

 few utricles intermingled. Scales dark fuscous. Utricle (young) 3 mm. 

 long, lance-ovate, long-rostrate. 



N. Fuegia, by Springhill. 



Var. densa Kuk. Spikelets more numerous, densely crowded, nearly all 

 males, rarely a few utricles intermingled. Scales dark fuscous. Utricles 

 (young) 3 mm. long, lance-ovate, long-rostrate. N. Fuegia (Dusen). 



C. Germana Boott, Macl., p. 282, should be deleted, being a synonym 



of C. Banksii. 



C. GOODENOUGHII Gay. 



Bracts shorter than inflorescence. Otherwise as in 28 (Vulgares). 

 Patagonia, Rio Chubut, Carren-leofu. Also in N. Asia and N. Amer.; 



Chili. 



P. 283 ; Carex hypoleucos Kukenth. (is Carex macrorrhiza Boeck, var. 

 simplex Kiikenth.). Culm smooth; Spikelets not glomerate, but crowded 

 into a dense ovate simple spike. Utricles large, rostrate, the base spongy, 

 rostrum smooth at the margins. 



C. INCOMPTA Franch. Macl., p. 283. 



This species is identical with Carex Darwinii Boott and should be 

 treated accordingly.
