Obs. I have not seen the flowers of this plant, which 

 was sent to me four years ago, from the Bury Botanic 

 Garden, as, I think, a Hertfordshire plant, gathered 

 wild there by the late venerable Sir Thomas CuUum. 

 Its shoots are more than twice the length of the last, 

 and its leaves are half as long again, often cylindrical 

 and more remote, and it is destitute of all pubescence 

 even when magnified. I suspect it is a maritime plant, 

 requiring a saline air, and perhaps a saline soil, to 

 produce its flowers. It bears a greater resemblance 

 to a Mesemhryanthemum than any other Sedum I am 

 acquainted with. 



Habitat prope Hereford ? H. 1/ . 



With the above Seda, mention may be here, and 

 appropriately, made, of two remarkable varieties of 

 Seduin acre, sent from the Bury Botanical Garden at 

 the same time with the precedhig; viz. 



acre. S. var. ^ dimmutum. multoties minus quam S. acre 

 Fug. Bot. tab. 839. An Sedum acre /3 glaciale, De- 

 Cand. Prod. V. 3. p. 407 ? 



Obs. Valde repens glomeratum, facie fere Lycopodii 

 parvi. Erecti rami steriles unciam alti; Jlorentes, vix 

 sesquiunciales. Folia magis conferta et minus viridia 

 quam in S. acre Eiig. Bot. tab. 839, in caeteris fere 

 omnino concordat. Sed caules 2-3-, rarius 4-flori so- 

 lum, nee 4-8, flori ut in S. acre. H. 1/. 



Obs. This diminutive plant, my judicious friend 

 Mr, John Denson, jun. (late Curator of the Bury 

 Botanical Garden) assures me was gathered wild on 

 Swaff'ham Heath, Norfolk ; by, I think, Mr. William 

 Christie, jun. of Clapham ; and it may eventually 

 prove to be a genuine species. 



The second variety may be called 



acre y elongatum. S. ramis pendulis 7-uncialibus; erectis 

 4-uncialibus, foliis laxe imbricantibus. 



Obs, This var. Mr. Denson mentioned not the origin 

 of. Its shoots are three times longer than those re- 

 presented in Eng. Bot. tab. 839, and its leaves are more 

 patulous and more distant from each other, and it pro-
