78 PATAGONIAN EXPEDITIONS I BOTANY. 



CAREX INCURVA Lightf. Macl., p. 283 (in Section Incttrvcz, 22). 



Stigmas 2 ; rhizome long, creeping. Utricles not marginally winged, 

 3 mm. long, somewhat inflated ; rostrum obliquely cut. Leaves narrow, 

 rigid, usually exceeding the culm. Spikelets 3-5, androgynous, crowded 

 in a subglobose head ; female scales broad, obtuse. 



Cosmopolitan ; Magellan, Sandy Point, Fuegia. 



This species is found also in S. Patagonia, to the north of Lago San 

 Martin, in swamps amongst the mountains at Rio Fosiles, in an altitude 

 of about 1,000 m. It is less common than C. capitata with which it is 

 very often associated. 



C. INCURVA Lightf. forma ERECTA O. F. Lang. 



Taller ; spike longer and wider ; utricles 4 mm. long. 



W. Greenland; Norway; Magellan. 



Macloskie gives a variety of C. incurva named humilis as occurring in 

 the Falkland Ids., but I have not been able to trace his authority for this 

 statement. As far as I am aware, neither the species itself, nor any form 

 of it, occurs in those islands. D. 



P. 283: C. involucrata Boott is C. sorosia Kunth. var. involucrata 

 (Boott.) Kiik. Occurs by the Rio Negro. 



P. 284: C. curtziana, is C. nebularum Phil., var. kurtziana Kuk.; occurs 

 also at Chubut, and Rio Corcovado. 



C. LECHLERI Phil. Macl., p. 284. 

 This is identical with Carex atropicta Steud., and should be deleted. 



C. LEPORINA L. Macl., p. 284. 



This species is very much akin to C. macloviana D'Urv., but does not 

 coincide with that species. It is, however, identical with C. ovalis Good. 



The present species does not belong to the flora of S. America. Sev- 

 eral authors, for instance Desvaux and Philippi, have named it as occur- 

 ring in Chili, but these statements refer to C. macloviana. C. leporina is 

 therefore to be deleted. 



C. MACLOVIANA D'Urv.
