556 EXTRACTS FROM CORRESPONDENCE. {^September, 



July 23r</, 1858. 



... I have been out for a few days, with some botanical re- 

 sults. You have probably found, like myself, that when one 

 goes to a neighbourhood known for rare plants one seldom finds 

 those one seeks for : one finds others which one did not expect. 

 It has not so happened with me this time, for during a day at 

 Matlock T found one of the two special rarities of that place, 

 Thlaspi virens, Bab. [alpestre, Sm.), still not entirely out of 

 flower ; and I have plenty for you as well as myself, if you would 

 like to have any. The other plants worth mentioning which I 

 found at Matlock were Arenaria verna, still spangling the hill- 

 sides with its blossoms ; Cardamine impatiens, plentiful ; Conval- 

 laria majalis, Arabis hirsuta, Campanula latifolia, and Geranium 

 pratense, all in abundance : its usual northern substitute, G. syl- 

 vaticum, I did not see. 



Other plants in Derbyshire : — Silene nutans, Dovedale and 

 Wyedale; Vaccinium Vitis-idaa, Chatsworth; Rosa villosa and 

 R. tomentosa, Monsal Dale and its vicinity ; Myrrhus odorata, 

 Millersdale ; also, I believe, between Castleton and Hathersage ; 

 CochJearia officinalis and Thalictrum flexuosum (or rather, per- 

 haps, T. calcarcum) , abundant on rocks above Castleton; Viola 

 lutea (which I prefer calling, with De Candolle, V. sudetica, as it 

 has a blue variety), on all mountains and hills near Castleton; 

 the blue variety occasionally ; Polypodium calcareum, in clefts of 

 rocks between Bakewell and Buxton; Cystopteris fragilis, in 

 similar situations there, and near Castleton; Carduus hetero- 

 phyllus, plentiful in wet ground by the river Wye, near Cowdale 

 turnpike, two miles from Buxton, on the Bakewell Road ; Pole- 

 monium coeruleum, on rocks by the same road, one mile from 

 Buxton, but so difficult to be got at that I only secured one spe- 

 cimen. . . . — July 30th, 1858. I will send Silene along with 

 Thalictrum. My specimens are not from Dovedale, though I 

 saw the plant there, but from Wyedale, about a mile above 

 Ashford, near Bakewell. The leaf of the Viola from New Brighton 

 is very much like that of some specimens I brought from Italy 

 under the name of V. montana or Ruppii, both of which are con- 

 sidered forms of canina. . . . — Among the Derbyshire plants 

 which I saw I omitted Allium vineale, near Matlock (at the 

 very top of the High Tor), and Saxifraga hypnoides, in various 

 places, but always much past flower, even in places where Carda- 

 mine prat en sis was still flowering. J. S. M.
