with soot. The sepals and petals are spotted, oblong, acute, 
and reflexed, so as to hang downwards. The lip, on the 
other hand, is fleshy, hooded, stained with pale purple, and 
either entire at the margin, or very slightly serrated ; but it 
does not cover over the column asis usual in the hooded 
Catasetums: on the contrary it spreads away at almost right 
angles. The column itself is short, deep green, and pro- 
duced at the point into a straight bristle, in front of which is 
placed a small and imperfect anther. In this masquing 
genus it is impossible to say what is a species and what is 
not. Judging by rules found good in other genera this is 
quite distinct from all species previously described ; judging 
from the evidence we possess concerning C. tridentatum, cris- 
tatum, and viride, we should suspect it to be a male form of 
C. atratum, or some such species. That, however, must 
remain for future enquiry. 3 
169. DENDROBIUM secundum. Botanical Register, t. 1291. 
A specimen of this pretty .plant, which has_ recently 
flowered with Mr. Knight of the King’s Road, has given me 
an opportunity of examining its structure carefully, and it 
proves so remarkable as to deserve especial notice. In the 
first place the lateral sepals and the base of the lip are so 
united into a spur, that their separate nature is entirely con- 
cealed towards the point of the spur. In the next place the 
rostellum is a deep two-lobed lip curved down over the stig- 
matic surface. The pollen-masses are in two pairs, and deep 
purple; and, which is extremely curious, they lie upon a loose 
hard transverse crustaceous gland, which seems to replace 
the gland and caudicula of Vande, and which projects be- 
yond the anterior edge of the anther, resting upon the two- 
lobed rostellum. The anther-bed itself is deeply excavated, 
and three-lobed, the anther adhering to the back lobe which 
is the narrowest.
