A native of the Southern United States. 
Stem reaching several feet high below the leaves, often 
branched. Leaves a hundred to a hundred and fifty or more in a 
dense rosette, lanceolate, thinner and more flexible in texture 
than in gloriosa, two and a half to three feet long, two to two and 
a half inches broad at the middle, narrowed to an inch and a 
quarter to an inch and a half above the base, more or less 
glaucous when young, the middle half flat on the face, the point 
subpungent, the edge entire or nearly so, marked with a brown 
line. Scape about equalling the leaves. Panicle ovate-deltoid, 
three to four feet deep; the lower branches a foot or more long. 
Perianth two to two and a half inches deep, tinged with red on 
the outside; the segments oblong-lanceolate, the inner ten to 
twelve lines, the outer nine to ten lines, broad at the middle. 
Filaments puberulent, ten to twelve lines long, hooked and 
thickened at the point, equalling the flask-shaped ovary. Stigmas 
ligulate, three to four lines long, emarginate only at the apex. 
In a broad sense not more than a variety of gloriosa, with 
which it is connected by intermediate stages.
