stvlo sequali apiculatum. Stigm. 3. I. G. Lemmon

Some few remarks may be added to this diagnosis, viz : 

 The culm is phyllopodic, and the number of spikes, the 

 pistillate, quite variable ; there is only one sessile stami- 

 nate spike, and with respect to the pistillate the upper- 

 most two or three are situated close to the base of the 

 terminal, the staminate, while the lower ones are remote ; 

 the number of pistillate spikes averages from two to six, 

 five being the most frequent. 12 Furthermore the scales 

 of the pistillate spikes (fig. 10-11) are mostly obtuse, and 

 fringed along the upper margin, but in some specimens 

 the midrib was extended so as to make the scale mucro- 

 liate; however such mucronate scales were observed in 

 spikes of which some of the other scales were simply 

 obtuse. In none of the mature specimens examined did 

 we observe any case where the scales were of the same 

 length as the perigynia ; they were constantly shorter 

 than these (iig. 11). The perigynium (fig. 12) is gener- 

 ally very narrow, and spinulose along the margins from 

 the middle of the body to the apex of the beak. Finally 

 in most of the specimens from Mount Paddo, "Washington, 

 kindly presented to the writer by Mr. W. N. Suksdorf, 

 the basal leaves were shorter and more spreading, rather 

 than erect, the bracts subtending the spikes were shorter 

 and narrower, and the color of the scales much darker 

 than in typical specimens. A similar dark color of the 

 scales and perigynia is, also, characteristic of the Califor- 

 nian plant in accordance with S. B. Parish, who has con- 

 tributed a very instructive paper dealing with Cyperacece 

 from Southern California. 13 



Car ex Lemmoni W. Boott is a member of the grex: 

 Stenocarpa, and is allied to C. luzul&folia W. Boott. a 

 very robust plant with broad, spreading leaves (basal) 

 and thick spikes. Of this species we have proposed a 

 variety strobilantha of which the perigynium is nearly 

 sessile, broadly ovate to almost globose, terminated by a 

 very distinct, bidentate beak. It is this plant which C. 

 B. Clarke has described under the name C. pseudojapo- 



12 As to the number of pistillate spikes we found in fifty-four specimens 

 from British Columbia, Vancouver Island, Washington and Oregon: 



18 specimens with five pistillate spikes. 

 14 specimens with four pistillate spikes. 

 14 specimens with three pistillate spikes. 



6 specimens with two pistillate spikes. 



2 specimens with six pistillate spikes.
