342 ASPLENIUM FONTANUM. 
He cannot have overlooked the circumstance of his having received à 
frond of the Halleri form of the species, and thus we must presume 
he had no confidence in the locality. 
In the ‘ Phytologist’ also for 1852, p. 519, the Rev. Mr. Bloxam 
has recorded two new localities: one on the authority of specimens n 
Dr. Power's (of Atherstone) Herbarium, gathered by Dr. Power m 
Wales, * between Tan-y-Bwlch and Tremaddock,” identified by Mr. 
Bloxam ; and “at the Swanage Cave, near Tillavilly, Isle of Purbeck, . 
Dorsetshire,” by Miss Power; but of which all the specimens had been 
given away. 
The latest published station is that announced by a letter (accom- 
panied by specimens) from the Rey. W, H. Hawker, received at à 
meeting of the Linnwan Society, December 23, 1852. That gentle- 
man had known it for several years growing abundantly and luxu- — 
riantly with other Wall-Ferns on the north side of an old wall, not far 
Jrom Petersham, very judiciously declining to publish the exact locality. 
Notwithstanding that the particulars of this discovery are fully related 
in the * Phytologist, 1853, the species is still omitted by Mr. Newman 
in his edition of * British Ferns,’ published in 1854. 
= Lastly, we may mention that Mr. Brown has in his possession true 
~ Specimens of this plant, labelled “as growing wild on rocks within two 
. miles of Alnwick Castle, Northumberland,” and sent by his Grace the 
. late (third) Duke of Northumberland, with other plants for cultivation 
at Syon. The remarks accompanying them are not in the handwriting 
of the late Duke, but apparently of some person in a much less educated 
. sphere of life, probably one of the gardeners; and as if corroborative 
of their being from the native station, it is added, “ pieces of rock 
_ were adhering to the roots." No responsible authority however is 
. In the absence of such authority as that now alluded to, and also 
where neither the locality nor the specimens have been certified by a 
competent botanist, we must, in endeavouring to determine what sta- 
tions are worthy of credit, consider the geographical position of the 
species on the Continent. We shall find, I think, that it is neither 
northern nor alpine. “Ad rupes, muros, in locis saxosis, non ad fontes;" 
“Germania australis, Helvetie, Gallie, Willd." Specimens in our 
own Herbarium are from such localities. Tt finds no place in the Floras 
of Mut ar 5 Norway, and Lapland. Most of the Russian stations are
