Guat. t. 27. 
A native of Mexico, discovered by Baron Karwinski in 
1827, and afterwards by M. Galeotti. It is one of the most 
distinct and magnificent species of the genus, and in the mag- 
nitude of its blossoms is second only to S. tigrina. The sepals 
are straw-coloured, or almost white, faintly and sparingly 
marked with clusters of little vinous dots j the petals appear 
transparent white, with large spots of intense crimson ; the 
lip is also a clear ivory white, except a slight discoloration at 
the base. The horns are of great size and strength, and taper 
into a kind of tendril, besides which they are exactly parallel 
with the epichilium, the form of which is almost linear, the 
two edges being as nearly as possible parallel with each other, 
and not a great deal broader than the column ; a mark by 
which the species is immediately recognized. 
Ihe present variety is a lovely plant, with large pure white 
flowers, richly but sparingly spotted with crimson. In the 
original S. Martiana the sepals are straw-coloured, and much 
more dotted with purple. Messrs. Rollisson have lately 
flowered it, and believe they obtained it from Mexico. It is 
as fine a thing as S. tigrina would be if its flowers were white, 
and is very sweet-scented. 
Now that the number of species of Stanhopea has been 
greatly increased, and that opportunities of examining them 
in a living state have occurred, it has become desirable that 
the genus should be reconsidered, partly for the sake of defin-
