The Species of Texas and the Southwest 587 



19. Sisyrinchium Langloisii Greene 



Suberect or ascending in loose tufts, 6 10 cm. high from a 

 cluster of delicate fibrous roots, slightly fibrillate at base, dull 

 green, turning dark when dry ; leaves firm, almost capillary, mostly 

 .2 5-. 5 mm. wide, the broadest becoming 1 mm. wide, equalling or 

 shorter than the stems, slenderly tapering to a somewhat indurated 

 point, closely striate-nerved, the edges smooth ; stem-leaves sub- 

 equal with the peduncles ; stems equally slender with the leaves, 

 the firm narrow margins smooth to denticulate ; node often low 

 down or subbasal, usually bearing 2-3 very slender, suberect, 

 smooth or denticulate peduncles 4-9 cm. long ; spathes about 1.5 

 cm. long, 1.5-2 mm. wide, the bracts rather stiff and firmly close- 

 nerved, narrowly attenuate, subequal or the outer one slightly longer, 

 sometimes becoming 2 cm. long, its margins narrowly hyaline 

 and connate for 4-5 mm. at base; inner scales brownish-tinged, 

 about half the length of the bracts ; flowers pale blue, on hair-like 

 slenderly exserted pedicels; perianth less than 10 mm. long, the 

 segments contracted or slightly emarginate at apex, mucronulate- 

 aristulate ; stamineal-column 4-5 mm. high, usually more than half 

 the length of the perianth ; anthers pale yellow, about 1 mm. long ; 

 ovary sparsely puberulent. 



The above description is based on type specimens received from 

 Professor Greene. Fruiting specimens from Texas referred here 

 are taller, more erect and broader-leaved, becoming 24 cm. high, 

 with the larger leaves 1.5 mm. wide; the capsules are globose to 

 broadly oblong and 2-4 mm. high on flexuously spreading pedi- 

 cels, their walls rather thin and transversely corrugate without 

 lateral nerves; the seeds are .75 mm. in diameter, black, globose 

 and rather deeply close-pitted. 



Related to S. fwcatum but smaller and more slender through- 

 out, the leaves and bracts firmer and more attenuate and closely 

 nerved, the pedicels more slender and exserted, the flowers smaller 

 and paler, the stamineal-column relatively longer, anthers smaller.
