 cylindric, 9-20 mm. thick; bracts mostly deciduous. 

 Wings caudate-acuminate. 6.5-7.5 mm. long; flowers subsessile; 

 plant essentially scapose, the stem naked or with one or two 

 leaves; seed rostrate at base. 

 Wings short-pointed to cuspidate, 5-6.8 mm. long; pedicels 

 2.2-4 mm. long; stems leafy; seed rounded at base. 

 Flowers turning green in drying ; wings cuspidate-mucronate. 

 Flowers remaining yellow in drying; wings short-pointed. 

 Racemes several or many, cymosely arranged at apex of stem and 

 branches. 6-13 mm. thick; bracts persistent. 

 Basal leaves spatulate or obovate, obtuse or rounded, 1-2.2 cm. 

 long; seed pubescent, ellipsoid. 

 Flowers white; pedicels 0.5-1 mm. long; capsule broader 

 than long. 

 Wings rather long-cuspidate, slightly narrowed at base; 



aril about one-half as long as seed. 

 Wings short-cuspidate, rounded at base; aril very minute. 

 Flowers yellow, turning green in drying; pedicels 1.3-2.3 

 mm. long; capsule as long as broad. 

 Basal leaves linear or lance-linear, attenuate, 3.5-14 cm. long;
