cut the record is' “Exposed rocks and sandy soils, occasional along 
the coast, rare inland.” Possibly other stations similar to those in 
Barnstable may be discovered, now that there is reason to look for 
them; in any case, it is now a part of the Cape. flora. 
We are accustomed to think of Opuntia as a subtropical genus, but 
while looking up references for this note I came across some informa- 
tion quite to the contrary as regards some species; it may be new to 
others, as it was tome. In the copy of the first edition of the Manual, 
at the Gray Herbarium, is a note against Opuntia vulgaris, in Dr. 
Gray's handwriting, “Grows N. on rocks to lat 50°. Dr. Richardson.” 
The Richardson seems to be Sir John Richardson,” who says, “Cacti 
are numerous on the eastern side of the mountains in the same parallel; 
and the smaller kinds, chiefly Opuntiae, range northwards over prairies 
to the 49th parallel, and perhaps further north. We gathered Opuntia 
glomerata or the Crapaud vert of the voyagers, on the Lake of the 
Woods." A still more northern range is shown by Macoun è “0. 
Missouriensis DC., Prickly Pear. We refer all our eastern forms to 
this species, but without being certain, as specimens have seldom been 
preserved. The Qu’Appelle valley, about two miles from its mouth, 
and the north bank of the Assiniboine, above Shell River, are the most 
eastern localities known. It is found at Moose Jaw Creek and at the 
elbow of the South Saskatchewan, and thence south and west to 
Long. 112? at the Hand Hills. A species which I believe to be the 
same, reappears again at the north bank of Peace River, Lat. 56? 12’, 
where it grows on the arid clay slope, exposed often to a temperature 
of 55? below zero."
