Plants of this very lovely Balsam were raised from seeds sent 
under the present name from Ceylon by Mr. Thwaites, blossom- 
ing in the summer of 1852. ‘They precisely accord with speci- 
mens sent many years before from about Rambodde and Matu- 
ratee, in the same island, by Mrs. General Walker, and which 
are the authority for the J. Hookeriana of Dr. Arnott in the work 
above quoted. That excellent botanist alludes to its affinity 
with the 7. grandis of Heyne, and I must confess that an authen- — 
tic specimen of that plant from the India Company (No. 4759 of 
Wallich’s Cat.) exhibits no difference, as far as can be judged 
from the dried plant, except in the long spur becoming more 
suddenly slender and filiform, so that the upper or superior half 
is infundibuliform or dilated, the lower filiform. The doubt 
might be solved probably could I have access to the volume of 
the ‘Madras Journal,’ where, according to Walpers, at. vol. ix. 
t. 4, the Z. grandis is figured. The present has, I think, the 
largest flowers of any known species, pure white, with deep blood- 
coloured veins. :
