576 Bicknell : Studies in Sisyrinchium 



a little exceeding the bracts, brown, large, 5-7 mm. long, broadly 

 oblong, many-seeded; seeds 1— 1 .2 5 mm. in diameter, globose or 

 obovoid, coarsely and prominently pitted, distinctly umbilicate. 



Based on a single collection by Drummond from San Felipe, 

 Texas, now in the Gray herbarium. 



A marked species apparently needing no comparison with any 

 other. 



6 . Sisyrinchium radicatum sp. nov. 



I 



Erect, rather stout and rigid, pale and glaucous, from 30-45 

 cm. or more high ; roots in a dense cluster from short woody 

 rootstocks, soft and thick, giving off slender fibrils. Basal leaves 

 mostly distinctly equitant in a short stiff cluster, a few longer ones 

 sometimes half the height of the stem, 2-3 mm. wide, somewhat 

 membranously broadened and hyaline-margined at base, stongly 

 close-nerved, acute with hardened tip, the edges smooth ; stem 

 stiff, 2-4 mm. wide, very narrowly firm-margined, the edges smooth 

 or obscurely roughened near the nodes ; nodes mostly two, de- 

 veloping stiff bracteal leaves, shorter than the 1-4 peduncles ; 

 peduncles 5-10 cm. long, more or less divergent and unequal, 

 smooth-edged and obscurely denticulate; bracts of spathe sub- 

 equal, acute, 17-22 mm. loAg, somewhat membranous, distinctly 

 fine-nerved, white-hyaline nearly to the tip, the outer one united 

 below for about 5 mm.; inner scales three-quarters the length of 

 the bracts or more ; flowers violet-blue, on slender, slightly ex- 

 serted pedicels, perianth about 10 mm. long, the segments short- 

 aristulate ; stamineal column 5 mm. high, anthers about 1.5 mm. 

 long ; ovary and young capsule densely glandular-puberulent. 



Southwestern Utah, St. George,Washington county, 1 877. D r - 

 Edward Palmer, no. 456 in herb. College of Pharmacy, N. V., 

 and herb. Gray. More nearly related to some of the California 

 species than to any of the Texas group. 



7. Sisyrinchium macrocarpon so. nov. 



Similar to stouter forms of S. ensigeriun, but stouter, stiffer and 

 less branched, with larger spathes, smaller flowers and larger 

 capsules. 



Very glaucous and pale, not changing color when dry, erect, 

 from 20-30 cm. high ; leaves over half the height of the stem. 

 2. 5-4 mm. wide, thick and very firm and stiff, strongly close-nerved, 

 very acute with hardened tip, the edges smooth or obscurely den- 

 ticulate-roughened ; steins 3 mm. or less wide, narrowly margined.
