The Species of Texas and the Southwest 577 



the edges finely cartilaginous-ciliolate ; node one, bearing two 

 rigid, suberect peduncles 6-8 cm. long, and a stiff subtending leaf 

 of about equal length, strongly nerved and ancipital at base ; pe- 

 duncles about 1.5 mm. wide, ciliolate ; bracts of the spathe 

 unequal, carinate and ciliolate, the outer one herbaceously pro- 

 longed and very acute, 2.5-4 cm. long, united for 5-8 mm. at 

 base, rather broadly white hyaline below the middle ; inner bract 

 2-2.5 cm - long, the tip acute and somewhat incurved; scales 

 about three-quarters the length of inner bract; flowers few, 2-5, 

 about 8 mm. long, the segments rather narrow, short-aristulate, 

 non-emarginate ; staminal column 4-5 mm. high, anthers 1 mm. 

 or more long ; ovary and capsule puberulent, the latter on rather 

 stout, erect pedicels, pale brown, broadly oblong or subglobose, 

 5-7 mm. high, the thickish valves sparsely venose. 



Arizona: Willow Spring, June 10-20, 1890, Dr. Edward 

 Palmer, no. 490a, U. S. Nat. herb. 



The flowering time is rather earlier than that of 5. demissum 

 Greene and much earlier than that of 5. amethy stinum, both of 

 which occur in the same reeion. 



8. Sisyrinchium longipedunculatum sp. no v. 



Pale green and glaucescent, erect, about 50 cm high, the simple 

 roots rather few and coarse. Leaves dry and stiff, erect, more than 

 half the height of the plant, 2-4 mm. wide, firmly close-nerved, 

 slenderly attenuate and very acute, the rather sharp edges up- 

 wardly close-serrulate: stems solitary or few, 2.5 mm. wide, stiff 

 and somewhat flexuously curved, the wing margins sharp-serrulate ; 

 bracted leaf much shorter than the two very long slender peduncles ; 

 peduncles sometimes 18 cm. long, about .75 mm. wide, subterete, 

 the very narrow margins smooth or obscurely serrulate ; spathes 

 very narrow, almost subterete and but 1.5 mm. wide towards the 

 base, the stiff, obscurely nerved bracts, tapering to the apex, almost 

 cuspidate-acute ; inner bract 2.6 cm. long, a little surpassing the 

 outer one which is very narrowly hyaline on the margins below 

 and united-clasping for nearly 7 mm. at base ; scales silvery white, 

 but little shorter than the bracts : capsules pale brown on nearly 

 erect pedicels about 30 mm. long, obovoid-oblong, large, becom- 

 ing 7-5 mm. high, the valves sparsely venose; seeds 2-5 in each 

 cell, large, 1.5-2 mm. in longer diameter, irregularly obovoid or 

 obovoid-oblong and angled, some of them compressed and nar- 

 rowly umbilicate, black, at first finely rugulose, at length smooth 

 and somewhat shining.
