inches high, with rosulate radical leaves, and a simple 
slender leafy scape, bearing a spike of white flowers with 
very long pcrianth-segments and minute stamens. Leaves, 
radical two to three inches long, sessile or narrowed into a 
stout or slender petiole, variable in shape, from linear-oblong 
to broadly elliptic, acute, irregularly toothed or almost en- 
tire, dark green on both surfaces, midrib very distinct, 
nerves very oblique; cauline leaves linear, quite sessile. 
Scape strict, acutely angled, as is the rachis of the spike. 
Spike at first oblong, obtuse, usually lengthening to four or 
five inches, strict, erect, many-flowered. Flowers quite 
sessile and appressed to the rachis; bracts and bracteoles 
none. Perianth about three-quarters of an inch in diameter 
across the segments, pure white; segments six, or four, the 
two lower being suppressed, or three, with the three lower 
suppressed, all widely spreading, strict, narrowly linear, but 
slightly dilated from the base to the obtuse point; two 
upper (when four or six) the longest, about half an inch 
long; two lateral about one-third shorter, ascending; two 
lower very short, deflexed. Stamens six, filaments very 
short and stout ; anther-cells reniform, adnate to the fila- 
ment, bursting outwards. Ovary globose, three-lobed, 
three-celled ; stigmas three, recurved, club-shaped, obtuse ; 
ovules two in each cell, adnate to the middle of the inner 
angle, anatropous, with ventral raphe and superior large 
open micropyle.—J. D. H.
