Epiphytal Plants. —On Saturday afternoon, when botanising 
at Churchill, Worcestershire, I noticed an unusual number of plants 
growing high up on pollard willows and other trees. Thus on one 
willow were common nettle, hawthorn, a willow herb, probably 
hirsutum, and the Wood Betony. Upon another willow I found a 
young ash tree, an alder, and a small willow herb. Again, upon one 
tree were a small filbert tree and a hawthorn ; while a wild raspberry 
occurred on one tree, and also a young gooseberry bush side by side 
with another young ash. Several tufts of grass were growing on the 
trees, but there seemed very little soil or decayed vegetation up where 
these plants were nourished, though the spot was very damp from an 
adjoining brook and marshy ground, in which latter I was glad to find 
Mimulus lutcus at one spot, a long way from any cottages.— Horace

Students’ Garden, Cannon Hill Park. —In a note to a very 
interesting paper on the Flora of the Rea Valley, which appeared in 
the June number of the “Midland Naturalist,” the writer, the Rev. 
H. Boyden, refers to this garden, and makes two suggestions, which he 
will be pleased to hear have not been overlooked. As soon as the site 
of the garden was decided upon I saw that the pool adjoining would 
form a very valuable adjunct, and that not only aquatic but possibly 
also marsh and bog plants might be grown there. Accordingly a series 
of “ pockets” have been constructed around the margin of the pool, and 
these, as well as the “ bays ” between them, will, I hope, soon be stocked 
with water-loving plants. The naming of the trees and shrubs, too, 
was a part of my original suggestion to the Park Committee, and the 
labels are in course of preparation. They will give the botanical and 
common names, together with the natural order and the countries of 
which the tree or shrub is native, so that while helpful to the student 
of botany it is hoped that they may also prove instructive and interest¬ 
ing to the genera! visitor. —Joseph W. Oliver. 
Ellesmere Excursion.— On Wednesday, June 23rd, I joined the 
botanical excursion of the Midland Union to Blakemere, Colemere, 
Crosemere, and Ellesmere meres. It was a bright, sunshiny day, 
though rather too windy for examining the more exposed meres. I 
had but a short time for collecting, but the list of micro-organisms, 
etc., that I recognised, which is subjoined, shows that there is a very 
good field for further study there. The most interesting find was 
Mehcerta Janus, which had not been previously found in England, 
having been found first in Scotland by Mr. John Hood. Frog-bit
