lip and petals. One or two of the species have appeared in cultivation, but 
are very rare. Trevoria is a very interesting Andine genus of three species, 
one of which was figured at page 296, where its character and history may 
be found. 
We now come to a group of genera whose characters are better known, 
and which are more frequently met with in cultivation. Laczena consists 
of two Central American species, whose flowers are borne in long pendulous 
racemes, with connivent greenish white fleshy sepals and petals, and a 
three-lobed lip, the front lobe being expanded, purple, and somewhat 
reflexed. Of Lueddemannia about four species have been described. The 
species are Colombian, and bear long pendulous racemes of yellow and 
brown flowers, not unlike those of Laczna in shape, but with a different 
lip. The genus was formerly confused with Cycnoches, but is very different _ 
in every respect. Acineta is nearly allied, and ranges from Mexico to 
Colombia, about eight or ten species being known. The flowers are fleshy 
and nearly globose in shape, with a very rigid three-lobed lip and a large 
fleshy crest. The flowers are yellow or whitish, sometimes spotted with 
brown. Several species are familiar in gardens. Lycomorium contains a 
single Colombian species, and is closely allied to Acineta in structure and 
appearance. It is not yet known in cultivation. 
Peristeria contains about ten Colombian and Central American species, 
most of them bearing short pendulous racemes of flowers, but in the well- 
known P. elata, the Dove Orchid, the flowers are borne in erect spikes. 
The flowers differ from Acineta in having the front lobe of the lip articulated 
and mobile. Houlletia is a native of Central America, Colombia and 
Brazil, and contains about ten species, two or three of which are well 
known in gardens. The flowers are rather less fleshy than in the preceding 
genera, and the side lobes of the lip very narrow and acute, while the front 
lobe is articulated, as in Peristeria. Neomcorea irrorata is a remarkable 
Colombian monotype which was figured as the frontispiece to our twelfth 
volume. It is allied to Houlletia, but in this case the whole lip is 
articulated, and owing to its shape and markings recalls a butterfly attached 
by its head. 
The next three genera, though much allied in habit, are very distinct in 
structure. Polycycnis contains about five species, natives of Central 
America and Guiana. The flowers are borne in drooping racemes, and 
have rather narrow, membranous sepals and petals, and a three-lobed lip, 
with a very long slender column, recalling that of Stanhopea. Cirrhza 
contains four or five Brazilian species, much like Gongora in habit, but with 
a rather different lip, the side lobes being narrow, elongate, and strongly 
reflexed, and the front lobe small and sometimes saccate in shape. Bentham 
places the genus near to Notylia, where it is clearly out of place. Gongora
