TRICHOMANES RADICANS INDIGENOUS TO YORKSHIRE 
By Tuomas Moors, Ese., F.L.S. 
«This beautiful capillary,” says Dr. Richardson, on the label attached 
to a specimen of Trichomanes radicans, “ I lately found in the moist 
and shady rocks nigh Bingley.” The specimen is preserved amongst 
Uvedale’s plants in Sloane’s Herbarium, vol. cccii. p. 66, at the British 
useum. On the faith of a specimen collected by Dr. Richardson 
“at Belbank, scarce half a mile from Bingley, at the head of a remark- 
able spring,” the plant was admitted by Dillenius into the third edition 
of Ray’s ‘Synopsis’ (1724). In later times it has only held a place 
in the flora of the United Kingdom, in virtue of its occurrence in Ire- 
land, but it may again establish its claim to rank as a genuine English 
plant, as was stated in the ‘Gardeners’ Chronicle’ (1863, p. 602). 
Some time ago I received a specimen from Mr. Walter Crouch, a ; 
gardener, who had gathered it in one of the fells in the Rydal district | 
of Westmoreland. The habitat was described as being on wet rocks, : 
and the plant was stated to occupy a space of about a square yard, 
not all in one mass but scattered. Of the identity of the plant, and the 
fact of its discovery, there is no doubt; but I have been informed by 
some Westmoreland pteridological friends, that there exists a suspicion 
of its having been planted some ten years before. Even if this should 
be so, it is an interesting fact, that it has survived and so far esta- 
blished itself as to pass unscathed through some of our more severe 
winters, ! 
I learn further, from Mr. J. F. Rowbotham, of Manchester, that h 
has more recently found Trichomanes radicans in North Wales, in a 
part of the Snowdon range. The precise locality it would be im- 
prudent to indicate, lest the information should lead to the eradication 
of the plant. The fronds were, as I learn, abundant, and remarkably 
fine; one of them, with which Mr. Rowbotham has kindly favoured 
me, is quite equal to the bulk of the Irish specimens in luxuriance of 
development, the frond having the broad or triangular-ovate outline of 
the more perfect examples of this Fern, and measuring about seven 
inches across the widest part, and nearly ten inches in length, in addi- a 
tion to a stipes of eight inches long. This specimen is not fertile, —
