Jung, rgt0.] _ THE ORCHID REVIEW. 165 
Southern United States and Mexico to Uruguay and Bolivia, and a good 
many species are well known in cultivation, several of them being very 
popular garden plants. 
Cattleya is very closely allied to Epidendrum, and indeed was included 
in it by Reichenbach, though there are marked differences in habit and 
structure by which the majority of the species are readily distinguished. It 
ranges from South Mexico to Uruguay and includes over forty species, the 
majority being among our most familiar garden Orchids. The nectary is 
entirely enclosed within the pedicel of the flower. Broughtonia is a West 
Indian genus of two species, in which the spur is adnate to the pedicel, but 
elongated and slightly swollen towards the base. Both species are occa- 
sionally met with in gardens. 
We now come to the genera having eight pollinia, the latter being prac- 
tically the only character by which Lelia can be distinguished from Cattleya. 
Over thirty species of Lelia are known, many of them being very familiar 
garden plants. The genus occupies two disconnected areas, one in Mexico 
and Central America, the other in Brazil. Schomburgkia is nearly allied 
to Lelia, and ranges from Central America to Colombia, about twelve 
species being known, a few of which are in cuitivation. Sophronitis is a 
small Brazilian genus, containing four or five species of dwarf habit, which 
_are very familiar garden plants. Brassavola differs from Lelia in its long 
beaked ovary, usually narrow sepals and petals, and mostly narrow fleshy 
leaves. It has a very similar distribution, and contains over a dozen species, 
several of which are familiar in gardens. B. glauca and B. Digbyana differ 
from the others in habit, and in having larger showy flowers, the latter 
species being remarkable for its deeply-fringed lip. Tetramicra is a small 
West Indian genus, having fleshy leaves and erect scapes of small flowers, 
with spreading segments, and the lower series of pollinia smaller than the 
upper. Leptotes, which Bentham united with the preceding, has two or 
three dwarf species, with fleshy, terete leaves, and flowers somewhat like 
those of a small Lelia. L. bicolor is well known in gardens, and there are 
two or three others, all natives of Brazil. Homalopetalum is a small 
Jamaican monotype whose affinity is obscure, for it has much the habit of 
the preceding, but a narrow petal-like lip, and a pair of oblong staminodes, 
which are free from the lip, but adnate to the base of the column. The 
lower series of pollinia are only half as large as the upper. It is a very 
distinct and interesting little plant, and is not yet known in cultivation. 
Bentham recognised one other subtribe of Epidendree, namely Steno- 
glossez, but it contains a few anomalous genera which can be included in 
_ Leeliez by a slight extension of its character. Bentham remarked: ‘“‘ The 
genera which I have collected in this subtribe are mostly small-flowered 
epiphytes, which have been generally classed either as sections of Epiden-
