bvanous margin of the sepals in the single specimen of C. alpinum 

 which is preserved in the same herbarium, and also labelled in the 

 handwriting of Linnaeus. The specimen of C. alpinum appears quite 

 glabrous to the naked eye, and has obtuse leaves, like some of my 

 Highland and cultivated specimens of the same species. Mr. Ed- 

 monston is doubtless correct in supposing his Shetland plant to be 

 the C. latifolium of Linnaeus, but these specimens in the Linnaean her- 

 barium show that he is quite wrong in the specific characters by which 

 he proposes to distinguish C. alpinum and C. latifolium. Probably 

 the best character will be found in the seeds ; those of C. latifolium 

 (from Perthshire and Sutherland) being muricate, while those of C. 

 alpinum (from Perthshire) are simply rugose. C, alpinum has larger 

 and paler seeds, with an oblique orifice to its cylindrical capsule. In 

 C. latifolium, the ovate capsule has the orifice scarcely or not at all 

 oblique ; though T cannot assert that these characters (drawn from 

 the form and orifice of the capsule) are constant in the living plants, 

 and they are often lost in the process of drying the specimens. I 

 write of the Linnsean specimens as they appeared to the unassisted 

 eye, not having any magnifier at hand when inspecting them. — Hew-

361. New locality for Jungermannia Turneri, Hook. In May, 

 1842, while walking through Tilgate forest, Sussex, I was fortunate 

 enough to gather Jungermannia Turneri, a species I believe found by 

 no one previously, except by the original discoverer, the late Miss 

 Hutchins, in Ireland. — Edward Jenner ; Lewes, August 21, 1843. 



362. Surrey localities for Schistostega pennata. In June, when at 

 Farnham, Surrey, I had the good fortune to discover Schistostega 

 pennata, in great abundance, in Mother Ludland's cave, in all its va- 

 ried and beautiful colours. St Catherine's Hill, Guildford, being of 

 similar sandstone, I was induced to search for it there, and found it 

 in the sand-martins' holes. — Jd. 



363. Erratum at p. 592. Will you have the kindness to substitute 

 the name of "Mr. Edward Jenner, of Lewes," for that of "Dr. Ed- 

 ward Jenner," in the Report of the Microscopical Society, (Phytol. 

 592). I shall, perhaps, at some fiiture time, explain my viev/s as to 

 the nature of Gomphonema, Achnanthes, Cocconema, &c., which I do 

 not consider to be Zoophytes. — Id. 



364. A word on Lastrcea spinulosa. Mr. Babington, in his excel- 

 lent * Manual,' has the following remarks on the plant usually known 

 by this name. —
