4 ' THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Among the chief items of Botanical interest of the year 1904, 
it may be mentioned that the following species have been added 
to the British Flora : — 
Fumaria occidentalis, described and figured in the ‘Journal 
of Botany,’ p. 218, by Mr. H. W. Pugsley, from specimens gathered 
at Newquay in Cornwall. Mr. A. O. Hume found it prior to 1901, 
and it was gathered by the Rev. H. J. Riddelsdell at Helston 
in 1900. It belongs to the section Agrariae of Fumaria^ hitherto 
not suspected to occur in Britain. It was, however, previously 
collected by one of our members, Dr. C. C. Vigurs, who has sent 
some beautiful specimens this year to the Club. Dr, Vigurs had 
known the Fumaria as a garden weed for many years, and indeed 
shewed it to Mr. Hume, In 1898 Dr. Vigurs sent me a specimen, 
but it was not in very good condition, and I was unable to refer 
it to any British form, and therefore asked him to send it again. 
A second supply left me unable to refer it to any British species, 
and I thought it must be a foreign casual. Still later I had another 
gathering, which I sent to Herr Freyn, but he also was unalile 
to name it. Mrs. Gregory, I believe, gathered it as F. capreolata 
at Selant, Cornwall, in 1895. 
Viola calcarea, Gregory. This plant, which is for the greater 
part the Viola hirta, L., var. calcarea, Bab., has been raised to 
a species by Mrs. Gregory (see ‘Journ. Bot.’ p. 67, t. 457 b.). 
Babington’s var. calcarea also included the plant known as V. hirta, 
var. Foudrasi (Jord.), which may be distinguished from V. calcarea 
by the hooked spur and greater hairiness, V. calcarea being almost 
glabrate, and having a very small, short, straight, conical spur. 
Epilobium collinum, Gmel. (see ‘Journ. Bot.’ p. no). 
Mr. C. E. Salmon reports that in the Herbarium of the Holmesdale 
Natural History Museum at Reigate are two sheets of E. collinum 
labelled E. roseum ? . , . collected by Dr, J, A. Power about 
60 years ago, probably from Scotland. In 1875 I collected a 
Willow Herb which I named E. montanum, in Strath Tay, which 
Prof. Haussknecht subsequently named, without any expression 
of doubt, E. collinum, and I recorded it in the ‘ Scottish Naturalist ’ 
for 1886, p. 30, but it is unnoticed in the ‘ Flora of Perthshire.’ 
Subsequently I visited the district, and after prolonged search was
