it into the garden of the Horticultural Society. It is 
very near S. oculata, from which it differs in the form 
of the lip and especially in the very short ovaries, a cha- 
racter pointed out to me by Mr. Loddiges.

quite distinct from any of the supposed varieties of S. 
oculata ; differing in the furrow of the anterior part of 
the hypochilium being closed up and not open, and in the 
exactly oblong form of the hypochilium; also from S. 
Huckeri in the absence of a strong tooth turned inwards 
from the apex of the cavity of the hypochilium ; besides 
which the angular condition of the base of the hypochi- 
lium indicates an approach to S. qucidricornis. The lip 
is pale yellow', with a few fine specks, a deep yellow hypo- 
chilium, the whole lower part of which is a deep chocolate 
brown. The flowers are deliciously sweet.

Mexico. This is a noble species, with the habit of 
S. Wardii, and its general colour, except that it is 
paler; but the epichilium is beautifully stained with pink, 
and the eyes of the hypochilium are very faint. It is 
distinctly separated by the peculiar form of the hypochi- 
lium, which instead of being oblong is so much narrowed 
to the base as to acquire an obovate form; by the entire 
want of lateral teeth on the margin ; and by the presence 
of a very strong indexed tooth, in which the wide, not 
closed up, fissure of the apex of the hypochilium termi- 
nates, We have received it from Messrs. Loddiges, and 
have named it in compliment to Sigismond Rucker, Esq. 
Junr., of Wandsworth, whose skill in the management of 
this noble genus is well known to the cultivators of 
Orchidaceae.
