822 CAREX 



C. atrata var. nigra Boott does not appear to occur in America. 

 The plant which has been referred here by various botanists is 

 specifically distinct, and may be briefly characterized from its most 

 striking features as follows : — 



Carex nova, n. sp. — Spikes three or four, globular or nearly 

 so, closely sessile and aggregated, the staminate portion incon- 

 spicuous ; perigynium very broad and conspicuously spreading, 

 usually light-coloured ; scales broad, often terminating in a cusp. 

 Mountains of Wyoming and Colorado and southward; evidently rare. 



Budge's C. gigantea does not appear to be the same as the plant 

 usually referred to that species, but a fuller examination of materials 

 in various herbaria must be made before definite notes can be had 

 concerning it. His specimen of C.folliculata Linn, is ft Michaux- 

 iana Boeckl. (C. rostrata Michx.)! 



Of Bobert Brown's northern Carices, all but C. attenuata are in 

 the herbarium of the Natural History Museum. This species was 

 seen in Herb. Hooker by Dr. Boott, and referred by him to G. 



rupestris All. 



C. affinis B. Br. Frankl. Narr. App. 763, was referred by Dr. 

 Boott to C obtusata Lilj. Three sheets were placed together in the 

 herbarium, the plants all collected on the same expedition, of 

 which two sheets are not labelled, but are evidently 0. obtmata, 

 although too young for positive determination. The third sheet is 

 Brown's type of C. affinis, and it is Kobresia scirpina Linn. 



G. concolor B. Br. Suppl. App. Parry's Voy. 218, which I 



doubtfully referred to C. lenticularis Michx. (Proc. Am. Acad. Arts 



and Sci. xiv. (n.s.) 86) is C. vulgaris var. alpina Boott (C. ngida 

 Gooden.). 



C. podocarpa B. Br. Frankl. Narr. App. ed. ii. 36, has been 

 entirely misunderstood. It is apparently only an aberrant form of 

 C. atrofutoa Schkuhr (C. ustulata Wahl.). From most specimens of 

 C. atro/usca it differs more or less in the entire orifice of its peri- 

 gynium, which is not at all puncticulate, somewhat narrower spikes, 

 and broader leaves. But ft atrofusca is a variable species, and I 

 see no constant characters to separate Brown's plant. The plant 

 which has passed for ft podocarpa B. Br. (Boott, 111. 197) is ft 

 macrochata Meyer.* 



C. pedata Linn. Sp. PI. e d. ii. 1384, is an enigma. The name 

 \v°in IS , lcatlon that Linna3iis meant to refer to C. omithopoda 

 Wild, the only other European species to which the name will 

 apply being ft digitata, which he himself described. Moreover, 

 Michehs figure to which he refers (Mich. Gen. t. 32, f. 14) is 

 unmistakably ft omithopoda. Unfortunately the plant does not
