588 Bicknell : Studies in Sisyrichium 





sometimes minutely scabrous, base of young tufts often chaffy 

 with the remains of dead leaves or finally loosely fibrillose ; roots 

 simple. Basal leaves shorter than or nearly equalling the tufts, 

 erect or ascending, firmly close-nerved, mostly 1.5-2 mm. wide, 

 acute with finally hardened tip, the edges smooth or cartilaginous- 

 denticulate ; stems erect or ascending or the outer ones spreading 

 and geniculate at the node, 1-2 mm. wide, the firm, narrow 

 margins cartilaginous-denticulate or ciliolate ; nodes 1-2, the 

 lower one mostly near the base of the stem ; stem-leaves firmly 

 erect, the lower one relatively elongated, the upper subequal with 

 the 2—4 approximate peduncles; spathes 12-20 mm. long, the 

 bracts equal or the outer one often, the inner sometimes, slightly 

 the longer, mostly denticulate on the keels, closely many-nerved, 

 acute, sometimes narrowly prolonged, the edges rather broadly 

 white-hyaline, especially on the inner bract which may be scarious- 

 obtuse at the apex ; outer bract connate for 3-5 mm. at base ; the 

 bracts, leaves and stem sometimes obscurely roughened with 

 minute points ; inner scales equalling the bracts or nearly so, 

 brownish-tinged ; flowers rather pale violet-blue on mostly well 

 exserted erect or recurved pedicels ; perianth 8—12 mm. long, the 

 segments short-aristulate, contracted at the apex or slightly emar- 

 ginate ; column 4-6 mm. high, one-half or more the length of the 

 corolla ; anthers nearly or quite 2 mm. long ; ovary puberulent to 

 labrate ; capsules apparently globose or suberect on much re- 

 curved pedicels. 



A small, tufted, subspreading species near 5. varians but, be- 

 sides difference in size and habit, firmer and more glaucous, the 

 leaves more strongly close-nerved, the first node much lower on 

 the stem, the stamineal-column relatively longer with larger 

 anthers ; the ovary mostly puberulent.
