PROCEEDINGS OF THE 
Epilobium rostum. In an obscure situation at Little Bad- 
dow, I found a few solitary specimens of what I take to be 
this. It seems to accord best with the description of that 
plant by Hooker and others. The thin and delicate leaf, and 
minute pink flower, render it a very elegant little species. 
Butomus umbellatus. This beautiful aquatic, which is not 
uncommon in this neighbourhood, I gathered in July at 
Springfield, near Chelmsford. 
Scutellaria minor. I obtained excellent specimens of this 
plant at Little Baddow Common, flourishing best among 
the furze bushes, with which the common is studded. 
Corydalis claviculata. Springfield, Essex. 
Gnaphalium minimum. This species, which I never ob- 
served till this year, I found at Danbury, growing with its 
allies (G. rectum and uliginosum). The specimen did not 
exceed the height of about six inches. 
Typha angustifolia. Abundant in a pond at Sandon, 
Essex. The narrow leaf and much smaller catkin appears to 
be the distinguishing features from T. latifolia. 
Myriophyllum verticillatum. This plant is found growing 
plentifully in an obscure and shaded pool in Springfield, 
and which was so encompassed by the Lemnce and Callitriche, 
as to be scarcely visible. When first discovered, which was 
in June last, I gathered specimens of it, and again in July ; 
it was curious to observe the difference in the foliage, 
as it gradually ascended out of the water. Those specimens 
which were gathered early, and covered with a dense mass 
of thread-like leaves, as they became exposed to the air, 
shot forth minute leaflets, giving the plant an ornamental 
appearance. Thus it will be seen, that however necessary 
water may be to vegetation, its maturity can never be effected 
without the assistance of the atmospheric air and the solar 
rays. 
Epipactis palustris. On Galleywood Common, near 
Chelmsford, though by no means plentiful. I have never 
observed this species attain a considerable size, and have 
universally remarked, that the tops of the leaves become 
decayed ; but from what cause I am unable to say. 
FERNS. 
The four undermentioned species of ferns were all gathered 
in one spot namely, Danbury Heath, Essex, which was 
overgrown with underwood, and rendered moist by numerous 
springs. The Aspidium Oreopteris, appears to me to be
