To those who are interested in the records for Yorkshire 
plants, reference may he made to 
Car ex laevigata (Smith), Dallowgill (Bipon), August 15th, 
1805, J. Dalton ; Car ex filiformis L., Tanfield Hall carr, 
J. Dalton, 1802. 
Among the rare and local plants in your Herbarium two 
examples may be given which will conclude these preparatory 
notes. 
Carex Davalliana, from Landsdowne, near Bath, which was 
presented by Sir J. E. Smith to the Bev. James Dalton. Sir J. 
E. Smith was the founder and first President of the Linnean 
Society and a personal friend of Dalton. The distribution 
of this Carex appears to extend throughout Southern Europe. 
In England the only authentic record appears to have been 
Landsdowne, Bath, but owing to drainage. &c., it has been 
extinct in this (Bath) district for many years. 
It is a dioecious sedge and resembles its ally, Carex dioica 
L., but does not possess the creeping stoloniferous rootstock of 
that species. These two circumstances may have assisted in 
its extinction, after the ground had been drained. 
The alpine cotton grass (Eriophorum alpinum L.) belongs 
to the Highland type of plants and is distributed through 
arctic and alpine Europe, N. America, and N. Asia. It has 
not been found in England, and the only station in Scotland, 
the Moss of Bestenet, Forfarshire, whence your specimens 
were obtained, has been drained, and there is no trace of this 
very rare and interesting plant now. In addition to the 
extreme rarity of this plant the specimens possess a value in 
consideration of their collectors. Sir IV. J. Hooker was the 
contributor of one specimen, and his name appears among 
the honorary members of your Society for 1824. For many 
}^ears he was Professor of Botany at Glasgow, during which 
time he trained many students whose names are associated 
with the chief botanical expeditions and literature of the present 
century. To Sir W. J. Hooker and his son Sir Joseph Dalton 
Hooker the botanists of the world are indebted for many 
valuable publications and for the position which Kew holds 
among the botanical institutions of the world. In addition to 
this record there are numerous specimens and evidence in your
