known as a botanist; and it is also observed that he is impa- 
tient of the action of those who would have a correct and 
lawful plant nomenclature. Perhaps some reason for his 
opposition to accuracy in naming things botanical may by 
and by begin to be obvious. Epw. L. GREENE. 
Nore on SEepuM RADIATUM.—The account given in the 
April number of Ernyruea of the small annual Sedwm found 
on Mt. Hamilton, and referred to S. radiatum, leads me to 
suspect that it is not of that species. My observations upon 
the Oregonian plant upon which Dr. Watson founded the 
species have taught me not that it bears “ leafy bulblets in 
the axils of the lower leaves,” but that it puts out stolons 
which have bulblets at their apex. They are produced in 
the fall, after the first rains; and these having attained some 
size the parent stock dies. This is a very different life his- 
tory and mode of propogation from that attributed to the 
Californian plant at page 85 of this volume.

A SEconD SPECIES OF THE GENUS Ramona.—That pretty 
Californian labiate which Mr. Bentham named Awdibertia 
humilis, and which I, in the second volume of Pittonia, trans- 
ferred to Salvia (along with most of the species of Bentham’s 
Audibertia No. 2), now flowering in the garden of the Uni- 
versity, has quite surprised me by displaying the corolla not 
of a Salvia at all, but of my genus Ramona; it must therefore 
take the name Ramona humilis. Epw. L. GREENE. 
BurraLo AND Pxiant Disrrisution.—In confirmation of 
the merited censure of Mr. Berthoud’s paper I have to say 
that Phus glabra is plentiful in parts of British America, 
which the buffalo never reached. It is also a fact that 
Opuntia Missouriensis as inhabiting the Lake of the Woods 
(Winnipeg) district, is found only on islands in that lake, to 
which places the buffalo never came. I took Mr. Berthoud’s 
“ Martynia”’ to be nothing more nor less than Xanthiwm 
Canadense, which grows in abundance throughout the buffalo 
region. JoHN Macovn.
