BICKNELL: STUDIES IN SISYRINCHIUM SES 
S. halophilum and S. leptocaulon both differ essentially from 
S. oreophilum by their thicker roots and smaller, thicker-walled, 
pale capsules. 
The only other simple-stemmed species of any of the Pacific 
states, S. dahvense and S. sarmentosuin, need no comparison with 
S. oreophilum, the former being a much larger plant in every way, 
and the latter differing conspicuously by its narrowly prolonged. 
foliaceous bracts, besides narrower and weaker leaves and stems. 
and smaller flowers. 
‘Sisyrinchium Greenei sp. nov. 
Mostly 25-45 cm. high, from fibrous, sometimes slightly thick- 
ened roots, pale or glaucescent green, often darkening or becom- 
ing brownish in drying. Leaves commonly about half the height 
of the plant and 1-3 mm. wide, sometimes rather thin and soft or 
becoming firm, varying from linear-attenuate and straight to acum- 
inate and somewhat curved, narrowly acute, the delicate nerves ap- 
proximate, or becoming well separated on the broader leaves, the 
edges smooth ; stems commonly terminated by one or two, or even 
three, slender but mostly short peduncles subtended by a usually 
shorter erect bractal leaf, sometimes bearing a leaf and axillary 
peduncle lower down, casually simple with terminal spathe, 1-3 mm. 
wide, narrowly thin-margined or winged, the edges smooth or ob- 
scurely denticulate near the node ; peduncles 3—10 cm. long, often 
extremely slender, slightly diverging and mostly a little unequal ; 
Spathes often purplish, usually narrow, 15-20 mm. long, the bracts 
rather firmly fine-nerved, equal, or either one slightly the longer, 
the outer one mostly acute, sometimes slightly foliaceous and be- 
coming 2.5 cm. long, united-clasping below for .o5~.07 mm., the 
inner one often scarious, obtuse ; inner scales mostly about three- 
fourths the length of the bracts ; flowers on slender, slightly exserted 
pedicels, delicate, pale violet-blue, about 10 mm. long, the seg- 
ments short-aristulate ; stamineal column 5-6 mm. long ; ovary 
glandular-puberulent ; capsule subglobose or obovoid, brown, 
firm-walled, 3-7 mm. high ; seeds numerous, apparently medium- 
Sized, 
Sierra Nevada Mountains from about midway in the state north- 
ward, extending into Oregon, ascending to at least 6,000 feet. 
Flowering mostly in June and July, although beginning to bloom 
in May, or even earlier, at lower altitudes. Named in honor of 
Professor Edward L. Greene.
