The plant is one of the smaller of this section; leaves densely 
clustered around the base of the stalk, ascending and erect, thick, 
fleshy, deeply concave, very glaucous, 6-12 inches long, £-2 wide, 2 0 
contracted above the very broad base, which is edged with sharp, 
straight, pale teeth, wider above the middle and terminated by an 
unusually long (1-2 inches) and slender, laterally compressed spine 
marked with a deep narrow groove half-way up; the hard and 
horny, dark colored edge of this spine extends down to about the 
middle of the leaf, bearing the crowded, strong, hooked teeth (2-3 _ / 
lines long) ; below the middle the teeth-bearing margin is herba¬ 
ceous. The stalk is, according to Dr. Parry, 4-10 feet high, 1-2 
inches thick below. The flattened branches of the panicle, almost 
horizontal below, longest (2-3 inches) in the middle and nearly 
erect upwards, divide into not very compact clusters of forked 
pedicels, 2-3 lines in length, the ultimate ones shorter, bearing a 
profusion of bright yellow flowers. Prismatic ovary a little shorter 
than the perigon and scarcely contracted at top; perigon 10-11 
lines long, tube only 1 \-2 lines long and wide, lobes about 9 
lines long and 2} wide ; filaments inserted at base of lobes, about 
twice their length ; anthers as long as lobes ; capsule 1 f inches 
long, 6-7 lines wide, pointed ; seeds 2\ lines in diameter.
