A native of Angola, discovered by Dr. Welwitsch, and, as will 
be seen from the plate and description, one of the most valuable 
additions that have been made for a long time to our stock of 
cultivated bulbous plants. 
Bulb large, ovoid, coated with membranous tunics. Leaves 
about half a dozen to a scape, suberect, fleshy, pale green, reaching 
a foot and a half to two feet in length, an inch broad low down, 
narrowed gradually to an acute point. Scape terete, the height 
of a man in the wild plant, so that, Dr. Welwitsch says, walking 
in the wooded meadows where it grows, you have to look up to 
see the flowers. Racemes moderately close, cylindrical, a foot or 
even a foot and a half in length, three inches broad when ex- 
panded. Pedicels one-fourth to half an inch long. Bracts linear 
or lanceolate-cuspidate, equalling or protruding beyond the 
flowers. Lower flowers twelve to fourteen lines deep; the seq- 
ments yellow, with a broad green keel, all about equal in length, 
three to four lines broad; the upper flowers srowing gradually 
smaller down to nine to ten lines. Stamens all fertile, the 
filaments filiform in the upper half, lanceolate in the lower half, 
valvately connivent at the base. Ovary ovoid, narrowed gra- 
~ dually into a filiform style half to five-eighths of an inch long. 
Stigma capitate.
