pure white to a rose-purple. The eye, however, is always 
yellow with a radiating, deep purple ring.

terminal. Peduncles almost an inch long, slender. Calyx 
with the éwbe funnel-shaped, the limb of five rather long, 
linear-lanceolate, spreading segments. Tube of the Corolla 
scarcely an inch long, very slender, generally curved : limb

standing close together, and arising from the mouth of the 
tube, unequal, pubescenti-glandular. Anthers yellow, in 
part enclosed by the transverse stigma.
