the States and Canada, but which is exceedingly scarce in Eu- 
rope,” was discovered by Professor Oliver to be a native of 
Connemara, Ireland; and Lriocaulon septangulare, peculiar in 
Kurope to the west of Ireland and of Scotland, is abundant in 
North America. Such views, entertained by so distinguished 
a botanist as Dr. Lindley, led Mr. Bentham, Dr. Hooker, and 
myself, to a further examination of the Spcranthes in question, 
on my receiving some living native specimens last year by the 
kindness of Lord Bandon. The result is, that the Irish S. gem- 
mipara and the North-American S. cernua are identical in all 
particulars, as the accompanying figures of the Irish plant will 
testify. 
in North America 8. cernua has a most extensive range. I 
possess numerous specimens from Newfoundland in the east, 
on the mainland through the whole plains of the Saskatchawan, 
and the Lake of the Woods; across the Rocky Mountains to 
British Columbia and Vancouver’s Island ; from all the northern 
and middle United States; and it is recorded in the Floras of 
South Carolina and Georgia, and of the Southern States ge- 
nerally. If 8. Romanzofiana should prove to be identical with 
S. cernua, then its north geographical limit is Unalashka, in the 
Russian dominions, but geographically pertaining to America.
