in August on the actual summit (about 3300 feet) of Ben 
Voirlich, Perthshire; just S. of Loch Earn, where, in com- 
pany with Carex rigida (Good), it formed the only vege- 
tation. 
At first it was taken for a very luxuriant form of montana 
(Hudson) which is common on the summits of many High- 
land mountains, but Mr. J. G. Baker, F.B.S., of Kew, pointed 
out to me the fact of its varietal distinctness from its pos- 
sessing three fertile fiorets ; hence it must be removed from 
Avenella. 
I exhibit specimens from various parts of the northern 
hemisphere ; normal forms of H. fiexuosa from Kersal Moor, 
Manchester, where it grows abundantly; also specimens 
from Surrey, Lithuania (Poland), Spain, and both Northern 
and Southern States of N. America. These last, collected 
by Buckley from the mountains of N. Carolina, appear 
sometimes to have only one perfect floret, and a rudimentary 
second, the English specimens invariably two, and the variety 
b. montana (Hudson), which I show from Lochnagar and 
Ben Macdhui, Aberdeenshire, two also. This variety is prin- 
cipally conspicuous for its large dark purple glumes. 
Aira alpina (L.) is reported from Ben Voirlich by Hr. 
Boswell, but I have never seen it there, and this grass is 
evidently not that species. It is always found viviparous 
in this country, and I have only seen it at the summit of 
Lochnagar, whence I show specimens. 
The only other British, or indeed European, form of this 
grass I have seen which might at all belong to this new 
variety, called Voirlich ensis, after the mountain on which 
it was observed, are from Glen Sannox, I. of Arran, where I 
have detected, in a small example I possess in my Herba- 
rium, collected in September, 1883, by Bev. Augustin Ley, 
and labelled montana, among a great many spikelets with 
but two florets, as is usual, one with an apparently almost, 
if not quite, complete third floret. It is most probable
