Spectres. 1. X. asphodeloides. Has. In New Jersey, and 
also very abundant on the summit of the Catawba ridge, 
North Carolina. The dilation of the filaments towards the 
base, the disposition of the styles, or rather stigmas, and 
the opening of the capsule by 3 external sutures in the — 
centre of each cell,in place of the internal margins of the 
cells or capsules, are characters of much more importance _ 
: than those which separate Helonias and Veratrum. 2. tenaz.

_ the scape not so far exceeding the leaves. Roots fascicu-

inches high, solid, rather thick than slender, nearly naked, 
or with a single leaf; spike 10 to 15 lines long; flowers 
crowded, numerous, (30 or more); bractes extremely mi-

with the petals and germ, subulate, flat, and cons ly 
dilated; anthers oblong, cleft at the base. Styles none; 
stigmas flat and circular, sessile. Capsules 3, distinct to
