one of these sprays at the July meeting of our Society.

FLOWERING OF “ DROSERA ROTUNDIFOLIA.” 
On the damp peat-moss about Loch Maree in the district 
of West Ross, Drosera rotundifolia and D. anglica are equally 
abundant. I have searched there for the fully expanded 
flower during perfect summer weather, but although seed 
was being produced abundantly the flower never seemed 
more than a half-opened bud. 
Anne Pratt records in The Flowering Plants of Great 
Britain, that she only saw the fully opened flowers of the 
Sundew after long watching. Darwin, in his Forms of 
Flowers, says: “The first flower stems which were thrown 
up by some plants in my green-house bore only cleistagamic 
flowers. The petals, of small size, remained permanently 
closed over the reproductive organs. These cleistagamic 
flowers produced an abundance of seed, later in the season 
perfect flowers appeared ;” and also, “with plants in a state 
of Nature the flowers open only in the early morning, as I 
have been informed by Mr Wallis, who particularly attended 
to the time of their flowering.” 
Then, again, Kerner, in a table showing the hours of 
opening and closing of a series of ephemeral flowers—that 
is, flowers which open only for a single day—gives for 
Drosera longifolia, hour of opening 10 to 11 am., and of 
closing 2 to 3 p.m. The same authority says :—“ Droseras 
open their flowers only under very favourable conditions of 
weather, and then only every other day. At any rate for 
D. longifolia it has been shown that, even in the finest 
weather, a flower bud opens on alternate days only.” 
I saw the flowers of Drosera rotundifolia fully opened, for 
the first time, last August (12th August 1900). It was on 
the Lomond Hills at twelve o’clock during a day of extreme
