outside smooth, dotted with pale purple on a pale (flesh-coloured ?) 
ground; inside with the ground colour varying from pale flesh-

round light purple (or crimson ?) spots, which pass into transverse 
broken lines within the tube, which at the base, around the outer 
corona, is entirely purple; outer corona of 5 pairs of acute deltoid 
teeth or of 5 deeply and acutely bifid lobes 3—} lin. long, dark 
purple-brown, all united at their base into a circular disk of a pale 
pinkish tint, margined with purple-brown between the lobes ; inner 
corona-lobes much overtopping the anthers, 1 lin. long, not reaching

at their base, connivent at the middle, slightly spreading at the 
upper half, pale purple. 
_ Var. 8, immaculata (N. E. Br.); corolla 13-1} in. in diam., scarcely or 
inconspicuously raised into a convex ring around the mouth of the tube, primrose- 
yellow, without spots, tinged with very pale purple at the base of the tube 
around the corona, scabrous as in the type, with the papille at the mouth and 
in the throat of the tube tipped with short acute pinkish hairs ; inner corona-lobes 
overtopping the anthers, about 1 lin. long, slightly gibbous behind ; otherwise 
as in the type. 
Var. y, pallida (N. E. Br.); corolla about 1} in. in diam., not or incon- 
spicuously raised into a convex ring around the mouth of the tube, pale primrose- 
yellow with light purple markings, smaller and fainter than in the type, and the 
surface much less scabrous, with small slightly prominent papilla, those in the 
throat being tipped with minute acute dark purple hairs; disk and lobes of 
outer corona dark purple-brown, with 5 slight ridges on the disk radiating from 
the base of the inner corona and ending in slight projections between the lobes ; 
otherwise as in the type. 
Var. 5, ecornuta (N. E. Br.); corolla 14-1} in. in diam., not or inconspicuously 
raised into a ring around the mouth of the tube, which widens upwards, pale

scabrous, with the papille in the throat and at the mouth of the tube tipped 
with a short stiff clavate dark purple hair; disk and lobes of outer corona dark
