me by letter, on my inquiry, that according to his opi- 
nion no true hybrid procumbens X saginoides exists in 
Switzerland, the plant of Brügger being a form of S. 
procumbens with occasional pentamerous flowers. In 
Prof. Schinz’s Flora der Schweiz, II, ed. 3, which is 
soon to be published, the reputed hybrid will appear 
as »S. procumbens f. inter mixta Beck». 
However, as I am not convinced that the hybrid 
spoken of is entirely missing in the Alps (see my list 
of localities below), I propose until further notice to 
accept Brügger’s name S. media for the hybrid combi- 
nation which he originally had in view. Though the 
description (see above) is very short, the identity of 
S. media with S. procumbens X saginoides from other 
countries does not seem entirely excluded. 
I am much obliged to Prof. Schinz for the informa- 
tion that specimens of Brügger’s S. media possibly might 
exist in Chur. I have applied to Prof. Chr. Tarnuzzer 
there, Director of the Rhätisches Museum, asking him to 
lend me the existing specimens. He has been kind enough 
to send me the collection of S. procumbens and saginoides 
from Brügger’s Herbarium, all revised by Dr. A. Thellung 
in Zürich. Among these plants only one small, unmoun- 
ted specimen without habitat is labelled »procumbens 
X saxatilis» by Brügger himself, but Dr. Thellung has 
noted on the label that it is a common S. procumbens 
with some pentamerous flowers, which I find quite correct. 
In the collection of S. procumbens of Brügger’s 
Herbarium, however, I have found a number of big and 
well preserved, specimens, which, in spite of the tetra- 
merous flowers, are no true procumbens. They are distin- 
guished from that species by the following marks: 1) 
colour dull green; 2) leaves straighter, longer, and more 
perfectly linear (in procumbens generally lanceolate-linear 
and a little recurved); 3) leaves more tufted in dense
