Rich as my Herbarium is in specimens of Thibaudia from the 
Andes of South America and of Mexico, there is not one that 
exactly corresponds with the present; and in no genus is it 
harder to refer the individuals to described species, even when 
aided by figures. Our plant is raised from seeds sent from the 
elevated mountains of Columbia by our Collector, Mr. Purdie, 
and it flowered first in the Greenhouse at Syon, in September, 
1847. It approaches, however, so closely to the specimens of 
T. Pichinchensis of Mr. Bentham, collected by Hartweg on the 
west side of Pichincha, and still more to the description of the 
latter author, that I am disposed to pronounce it a glabrous 
variety of that species. From Professor Jameson I have a 
Thibaudia (no. 293) “from woods on the western side of 
Pichincha and another “ from Pulalaqua, 9,000 feet above 
the sea-level ”, which I am inclined to consider identical with 
our present plant, but the leaves are blunter and the flowers 
narrower. It is only from an extensive suite of specimens, or 
from an investigation of living plants, that we can arrive at any 
accurate conclusions; and no genus is more worthy of a full 
monography. The present species is eminently beautiful, with its 
DECEMBER IST, 1847.
