veins. The species is easily distinguished by its colouring, by the 
deeply saccate petals, and by the long forks of the appendage to the 
lip. The flowers exhale a heavy disagreeable scent. It is very 
frequent on the sandy downs, but does not seem to bear a higher 
elevation. The figure in the Bot. Register is, for the most part, 
excellent.

—Glabrous, erect, 5-12 in. high; stem straight, leafy; leaves several, 
somewhat distant, from a broad-sheathing base narrow-linear, com- 
plicate, acute, erect or spreading, 1-2 in. long; spike densely flowered, 
oblong, 1-8 in. long, about 3 in. wide ; odd sepal linear-oblong, 
channelled; the connate side sepals roundish, emarginate, ascending ; 
petals rounded, very concave, veined, the mouth of the hood wide and 
nearly square, the whole nearly 3 lines wide; limb of the lip 
projecting, long-clawed, then dilated, with a rounded, cuneate, emar- 
ginate extremity, the appendage viewed from the front cordate, 
vaulted with a projecting curved keel, sloping downward at the back 
without any projection; arms of the rostellum nearly horizontal, 
spreading on either side of the lip, and holding on their posterior 
surface the distant cells of the anther; glands of the pollinia with 
their viscid surface facing towards the back of the flower; stigmas 
two; ovary narrowed suddenly to the apex.

The hood of the flower is a light yellow, the lip and appendage 
greenish. The species may be readily distinguished from C. bicolorum 
by the long claw of the limb of the lip, and from C. orobanchoides 
by the absence of any tails to the appendage. It does not appear to 
occur frequently on the Peninsula. 
Prate 20, —Fig. 1, flower, front view x 6 diameters. (Note, the two projecting 
arms between the anther-cells and the appendage to the lip have been inserted by 
an accident and should be deleted); 2, flower, viewed obliquely from behind x 6; 
3, column and lip, front view x 10; 4, ditto, back view x 10; 5, ditto, side view, 
the anterior side to the right x 10; 6, a pollinium, mag. In the foregoing figures 
BS indicates the back, or odd sepal; SS, the connate side sepals; a, the anther; 
g, the gland of the pollinium; s, one of the stigmas separated from the other by 
the appendage of the lip. In figs. 1and 3, Lshews the limb of the lip; in figs. 4 and 
5, L (by a mistaken lettering), indicates the appendage of the lip.
