and on several new Species of Roscoea.

4. R. spicata ; spica exserta multitiorti coarctata, calyce emar- 



ginato nudo, foliis lanceolatis. 



5. R. capitata ; spica exserta capitata multirlora, calyce bicus- 



pidato ciliato, foliis linearibus. 



These new species all partake, more or less, of the habit of the 

 original one, and are well distinguished by characters derived 

 from the calyx, that being the part, in Roscoea, in which the 

 real specific differences principally reside. 



Returning by Matlock, I spent a fortnight, in the latter part 

 of July, in revisiting that beautiful scenery, which I have, in the 

 course of thirty years, so often explored. Here J had gathered, 

 in 1790, the Hypnum recognition ; but for want of noting the 

 precise spot, I had never been able, in any subsequent visit, to 

 find this rare and elegant moss again ; nor has any other botanist, 

 I believe, ever noticed it in Britain. It grows, copiously enough, 

 among some large massy stones and rocks, overshadowed with 

 trees and brush-wood, behind the principal inn, called the Hall. 

 A steep and devious path, of difficult ascent, leads up the hill to 

 these rocks, which, being mentioned in English "Botany by the 

 epithet of romantic, have obtained exclusively the appellation of 

 " the Romantic Rocks," and are pointed out by the guides to 

 strangers under that name. Here grow Paris quadrifolia, Poly- 

 podium calcareum, and numerous, though not the most uncom- 

 mon, Orchidea. 



The Hypnum recognition clothes the surface of these shady 

 broken rocks, and fills up many of their interstices, in loose 

 patches or tufts ; but the capsules are rather uncommon. They 

 are perfected in July or August. 



This moss being, as I trust, clearly defined in the Flora Bri- 

 tannica, and figured in English Botany, tab. 1495, I am some-
