This charming plant makes the third species now in 
our gardens, of a genus, which, in the spring of 1844, was a 
botanical puzzle. Such is the progress of scientific discovery 
when promoted by horticultural enterprise. 
All the species have been found by the fortunate exer- 
tions of Mr. Linden. One of them (A. Clowesti) was met 
with in low bottoms, in the midst of forests, in Venezuela, 
growing in the ground. The history of the two others is 
unknown. One of them ( A. uniflora) exists in Mr. Linden's 
herbarium, but by some mistake in the ticketing it is marked 
there as a Cuba plant; the other was sent to Mr. Rucker, 
whose specimen is now represented, and its locality is unknown. 
A. Rucheri is immediately recognized by its flowers 
having deep crimson spots on a yellow ground, and a deep 
crimson lip. The form of the latter again approaches that 
of A. Clowesii, but it is less hairy, and the lateral lobes are 
blunt, as well as shorter. Moreover, the flower is not 
resupinate, in the common acceptation of the term. The 
Species was among the most striking of all the Orchids
