“This plant was imported from Rio in December, 1841, 
by Lieut. Christopher Smith, of H. M. packet “ Star,” and 
added to Sir Charles Lemon’s collection at Carclew, where it 
flowered in May, 1843. Like others of this genus it proves 
to be only interesting as a subject for the Botanist, who, on 
dissecting the various parts of the flower and examining them 
through the microscope, cannot fail to be highly delighted 
with their singular construction, and the beautiful frosted 
appearance they present. 
“ Stem round, erect, from two to three inches high, 
brownish green, with a single joint about an inch from the 
root, surrounded and embraced by a brown sheathing bract, 
which extends nearly to the base of the leaf. Leaves ovate- 
oblong, slightly curved and hollowed in the centre, about two 
inches and a half long, and an inch broad, very thick and 
leathery, of a brownish green colour. Flowers six, sometimes 
seven, arranged alternately in a close raceme, issuing from a 
two-valved brown spathe at the base of the leaf, and extending 
about an inch and a half along the midrib. Sepals fleshy,
