BICKNELL: STUDIES IN SISYRINCHIUM 381 
There seems, indeed, good reason to suspect the existence of 
a group of closely related simple-stemmed species inhabiting nearly 
the same general region, which on present material it is impossible 
to disentangle effectually from S. halophilum and S. leptocaulon.

The original description of S. /eptocaulon was drawn from the 
Specimen first above cited together with other material from Ne- 
vada and Utah less evidently distinct from S. halophilum. Of the 
additional specimens here recorded, that from Soda Springs, while 
clearly related to the Lake Tahoe type, shows a greater size for 
the species and a wider divergence from S. halophilum than has 
hitherto appeared. The stiff, narrowly margined stems are 45-70 
cm. tall and about 1.5 mm. wide; the broadest leaves, nearly 2.5 
mm. wide, are strongly rather few-nerved and more or less white- 
glaucous ; the bracts are finely close-striate, the outer one stiffly 
short-pointed, scarcely surpassing the inner, and 2—2.5 cm. long ; 
inner scales crowded, sometimes exceeding the shorter bract ; 
pedicels close-fascicled, somewhat exserted; capsules pale, thick- 
walled, finely rugulose, 2.5-5 mm. high; seeds 2-3 in a row; a 
mature seed is nearly 2 mm. in diameter, irregularly compressed- 
Subglobose and very minutely rugulose. 
It is impossible to derive a clear understanding of either this spe- 
cies or S. halophilum from the scant material so far collected. While 
extreme examples of each appear obviously distinct, their relation- 
ship is confused by certain specimens which cannot be satisfactorily 
assigned at the present time. As already intimated there is good 
reason to believe that more than two species enter into the problem.

Stems simple, or occasionally developing a single terminal 
peduncle with subtending leaf, 10-25 cm. high from slender fibril- 
lose roots; pale glaucescent green, showing some discoloration 
when dry. Leaves about half the height of the stems, firmly
