two very distinct marginal nerves ; the nut is triangular, 

 much smaller than the utricle, and stipitate ; there are 

 three stigmata. 



The specific name is unfortunate, as are geographical, 

 specific names in general; the species, originally estab- 

 lished upon a plant from Montana, has since been col- 

 lected in Idaho, in Alberta, British Columbia, and Yukon. 



Car ex venustula Holm 7 (figs. 1-5). 



This species is a near ally of the preceding, but is 

 readily distinguished by the long leaves of the vegetative 

 shoots, and by the pistillate scales being obtuse to aris- 

 tate, much shorter than the perigynium, which is minutely 

 granular above. 



By Kukenthal (I. c. p. 412) these two species are con- 

 sidered identical with C. spectabilis Dew., together with 

 the phyllopodic C. microchceta Holm ; beside that a part 

 of the specimens of the former (C. Montanensis) has been 

 referred to C. podocarpa. 



The section "Settee" Kukenth. seems untenable, since 

 it is characterized as containing only aphyllopodic 

 species ; but among the species referred to this section 

 we find the following phyllopodic: C. podocarpa E. Br., 

 C. microchceta Holm, C. nesophila Holm, and C. littoralis 

 Schweinitz. 



By eliminating Carex podocarpa R. Br., so far entirely 

 misunderstood, the identification of several northwestern 

 Carices becomes facilitated, and to no small extent. 

 Carex macrochceta C. A. Meg. at its various stages, and 

 especially the younger ones, cannot possibly be con- 

 founded with C. ustulata Wahlenb., a phyllopodic species ; 

 and Carex spectabilis Dew. with the scales merely mucro- 

 nate, of a lighter color, is sufficiently distinct from C. 

 ustulata Wahlenb. as well as from C. macrochceta C. A. 

 Mey. These three species are actually those that have 

 hitherto been confounded with the troublesome C. podo- 

 carpa R. Br. "With respect to C. Montanensis Bail., and 

 C. venustula Holm, both aphyllopodic, these cannot be 

 considered conspecific with the phyllopodic C. micro- 

 chceta Holm; neither can the phyllopodic C. nesophila 

 Holm be looked upon as representing a variety (sub- 

 rigida Kukenth.) of the aphyllopodic C. macrochceta C. 

 A. Mey.
