Shortly caulescent or subsessile. Leaves thirty to forty in a 
dense rosette, ensiform-spathulate, two to two and a half feet 
long, three to three and a half inches broad at the middle, 
narrowed to two to two and a half inches above the dilated base, 
firm in texture, moderately thick, scarcely curving, the face 
nearly flat, both sides glaucous-green, narrowed gradually into a 
point tipped by a pungent channelled red-brown spine, the 
prickles of the margin small, deltoid, subpatent, a quarter to half 
an inch apart. Scape, including the panicle, twelve to fifteen 
feet high, its lower bracteiform leaves reaching a foot long. 
Panicle a foot and a half broad, with several rather close erecto- 
patent branches bearing the flowers in dense ascending terminal 
clusters. Perianth three and a half to four inches deep, nar- 
rowly funnel-shaped, the cylindrical ovary half its length, the 
lanceolate permanently ascending yellowish green divisions about 
an inch long. Anthers about an inch long, quite exserted.
