233 Hudson's spleenwoet. 



immediate neighbourhood, I discovered it in one or two other places, and 

 in one of these abundantly, covering the dry surface of a rook completely 

 sheltered from rain ; and, though its roots are almost exposed, and a slight 

 pull detaches it from the rock, it grows in the greatest luxuriance, one 

 frond which T gathered measuring eighteen inches in length. I have ob- 

 served, in all the fronds of this fern which I have gathered, that the rachis 

 is, throughout its entire length, furnished with linear scales, a character 

 which best distinguishes it in all its forms, and even in its very young state, 

 from Asplenium Adiantum-nigrum." — Phytol. i. 75. I am indebted to 

 the Botanical Society of London for a very beautiful series of specimens 

 collected by Mr. Thwaites in this locality; and Mr. Thwaites has most 

 obligingly sent me his own magnificent specimens for inspection. 



Devonshiee. — The Rev. W. S. Here has obligingly sent me specimens, 

 accompanied by the following habitats : — Morwell Rocks, on the banks of 

 the Tamar ; rocks on the Tavy, opposite Virtuous Lady mine ; rooks near 

 Cann Quarry, on the banks of the Plym ; and upon a damp mud wall at 

 Buckland Monaohorum. In addition to some of these localities, Mr. Ralfs 

 informs me he has found it near Tavistock, and by the sea at Salcombe. I 

 am indebted to Miss Griffiths and Mr. Beynon for specimens from Tor- 

 quay, where it seems first to have been observed by Mr. Beynon in 1842, 

 deeply seated in the interstices of a stone wall, of loose open construction, 

 and having a southerly aspect, not far above high-water-mark, near the 

 mouth of a small brook about half a mile from the town. 



Cornwall. — I am indebted to Mr. Greenwood for some fine specimens 

 gathered near Penzance. Mr. Ralfs informs me it is common in many 

 places near Penzance and St. Ives. Mr. Watson gives me the former of 

 these looahties. Mr. D. Peirson informs me he has found it at the Mana- 

 cles, the Logan Rock, &c. . and Mr. E. T. Bennett says he has found it on 

 St. Michael's Mount, and that it is exceedingly abundant on hedge-banks 

 in the neighbourhood of Penzance. 



Sussex. — I am indebted to Mr. S. L. Howard for a specimen found on 

 the High Rocks, Tunbridge Wells, and to Mr. E. Jeuner for others from 

 the same station : under the guidance of the last-named gentleman, I had 

 the pleasure of seeing it growing here in August, 1843. Mr. Borrer and 

 Mr. Jenner have also observed it on rocks in Bridge Park. 



Kent. — I am indebted to Mr. E. Jenner for specimens from rocks 

 facing the High Rocks, near Tunbridge Wells ; and, conducted by that 

 gentleman, I had the pleasure of seeing it still growing there in August, 

 1843. A stream running between the two series of rocks separates Kent 

 and Sussex, and the fern grows on both sides of the stream. 



Channel Islands. — " The next plant to which I du-ected my attention 

 was Asplenium lanceolatum, as I had found more trouble in gi-owing this 

 plant, either in or out of a case, than with most other ferns, either British
