PROCEEDINGS OF THE 
MARCH 2nd. 
John Reynolds, Esq., Treasurer, in the Chair. 
Previous to the ordinary business of the evening, Mr. D. 
Cooper delivered the first lecture on Botany. 
Mr. W. H. White read the following Paper on a new 
species of Epilobiura, communicated to him by M. Den- 
Kalaar. 
In 1830, a collection of seeds was sent from the Botanical 
Garden of St. Petersburgh, by Dr. Fischer, to the Botanical 
Garden of Louvain, the greater part of them from Central 
Russia. Among the number of packages was one of an Epi- 
lobium, without any specific name, and with the indication 
new species. 
The following particulars have been transmitted to me by 
M. Denkalaar, chief gardener at the Botanical Garden 
Louvain, relative to the culture of this new species of Epi- 
lobiurn ; and, as it contains some interesting remarks, I 
thought I could not make better use of them than by laying 
them before this Society. 
This plant has been cultivated with the greatest care; and 
from a minute observance of its developments, and researches 
made into its characters, the cultivators have become con- 
vinced that up to the present time, this species has neither 
been described nor cultivated elsewhere. In order, therefore, 
to give a faithful exposition of its characters, and to make it 
better known to the botanical world, the following specific 
denomination has been given to it, in accordance with the 
principles of the angustissimum and rosmarinifolium. 
“ Our plant has a straight stem, much branched, branches 
diffused and silky, furnished with alternate leaves, lanceolate, 
acuminate, and of a silky whiteness. Its flowers, disposed in 
loose ears, are at considerable distances, solitary, and of a 
pale rose colour; stigma quadrifid and rather bent; the pod 
of the same length as the peduncle. 
“ This description sufficiently indicates that the species in 
question, belongs to a generic group, designated by Decan- 
dolle, in his Prodromus, by the name of Chammierion , conse- 
quently to the same series in which is placed the Epilobium 
angustissimum — Curtis.
