according to Nuttall, is found so far south as New Jersey in the United States. _ The N. W. specimens
have certainly narrower sepals and lip than the others.

H a b . Newfoundland. Miss Brenton; and throughout Canada to Lake Winipeg and the Rocky Mountains.
U r Richardson. Drummond. N. W. America, in the Blue Mountains.—Very nearly allied to the
preceding, and often confounded with it. Sepals broader, and, as well as the petals, chocolate-coloured.
Lip deeper yellow, Battened as it were above and below, the sides swelling out. It is, I believe, the more
generally diffused of the two species in. British N. America.

Drummond. A very remarkable and most distinct species, found, as far as I know, by no naturalist except
those now mentioned. It is admirably described by Dr Richardson.

H ab . Canada; Montreal (Messrs Chandlers and Buckingham). Goldie. Portage of the Grand Rapid
of the Saskatchawan. Drummond.—Only two or three specimens were gathered, and those in fruit; but
roots were brought home which flowered in the Belfast Botanic Garden.—A small species, readily distinguished
by the distinct sepals and lip coming to a deflexed point at the apex below, so as, in some directions,
to resemble the head of a sheep or ram.
7. C. guttatum (S w .); caule diphyllo, stam ine sterili ovato em arginato deflexo, sepalo

H a b . T wo specimens only, with withered flowers, were gathered by Dr Richardson at Fort Franklin,
on the Mackenzie River. Unalaschka, most abundant. Chamisso.—Flower rather small, beautifully mottled
with purple and white. The leaves always turn black in drying.
