glossy green, very broadly lanceolate, subacuminate, flatly concave, 12-20 by 40-60 cm.; 
spine red-brown, smooth, polished toward the end, somewhat flexuous, triquetrously acicular, 
narrowly round-grooved to the middle and involute below, 3-4 by 25-30 mm., shortly decurrent; 
prickles 10-15 mm. apart, 3-4 mm. long, commonly upcurved above and recurved below, 
slender from lunate bases often on green prominences, the intervening margin a little concave. 
Inflorescence scarcely 3 m. high, the upper half or more narrowly oblong-paniculate with ascend- 
ing branches; bracts broadly triangular, imbricated; pedicels scarcely 5 mm. long. Flowers 
yellow, 40-45 mm. long; ovary 20-25 mm. long, about equaling the perianth, oblong; tube 
open, about 4 mm. deep; segments 4 by 15 mm., shorter than the ovary; filaments inserted a 
little below the throat, 30 mm. long, twice as long as the segments. Capsules broadly oblong, 
25 by 30 mm., very shortly stipitate and beaked; seeds?. Freely bulbiferous.
