except in Cambridgeshire." It flourishes here in some plenty, inter- 

 spersed with Scirpus Tabeinaemontani, and that most beautiful of the 

 Carices, C. pseudo-Cyperus. The other less common Carices that 

 this small watering-place affords to the botanist are C. pulicaris, C. 

 teretiuscula, and C. intermedia. The rare C. digitata was noticed at 

 Roche Abbey by the Rev. G. E. Smith. 



GraminecB. Among the Gramineae I may record Glyceria aquatica, 

 with stems full six feet high, Poa rigida, and Brachy podium pinnatum, 

 on dry limestone soil. 



Filices. The local Lastraea Thelypteris occurs in the fens at As- 

 kern with fronds above two feet long. The soil is exactly such as 

 Mr. Newman observes to be suited to the growth of this species, 

 " moist and soft, so that the rhizoma can extend itself with rapidity 

 and freedom."* L. Oreopteris, a fern, as its name would imply, of 

 mountain heaths, occurs in Melton Wood, and fruits in this situation 

 abundantly, the frond rising to the height of above two feet, and 

 emitting, when bruised, a fine aromatic odour from the resinous 

 globules which dot its under surface. Polystichum angulare grows 

 in plenty on Edlington Crags.

Adiantum Capillus- Veneris not found in Derbyshire. 

 By James Backhouse, Junr., Esq. 



I have seen Henry Ecroyd Smith's specimens of [so called] Adian- 

 tum Capillus-Veneris, recorded (Phytol. iii. 11) as growing on the 

 Peak of Derbyshire, and I can certainly say that they have no claim 

 whatever to be classed under the genus Adiantum, being evidently 

 seedling forms of Asplenium Trichomanes, with the leaflets more at- 

 tenuated and rather more incised than usual ; probably from having 

 grown in a moist, shady place, or amongst thick vegetation. H. E. 

 Smith is, I believe, quite satisfied on this point now. In this state 

 there is a strong resemblance in the leaflets to those of A. Capillus- 

 Veneris.
