These branches were much stronger on M. verticillata, even thicker 

 and longer than the central stem on some of the plants ; whereas those 

 of M. crispa were comparatively small and short. 



Besides the differences above noted and confirmed, I find some 

 others which increase the probability of the two plants being suffi- 

 ciently distinct as species. The flowers of M. crispa are larger, with 

 their petals scarcely exceeding the calyx, and more widely lobed than 

 in the other species ; the axis of the fruit is elongated conspicuously 

 above the carpels; the stem almost destitute of hairs. In M. verticil- 

 lata the flowers are smaller, with narrower petals, which are nearly 

 twice the length of their calyx, aud the lobes of which do not divari- 

 cate like those of the former ; the axis of the fruit is broader and 

 shorter, scarcely exceeding the carpels ; the stem is sprinkled with 

 stiff hairs, disposed in a stellate form.

Localities for Botrychium lunaria, and Inquiry respecting Sedum 

 Forsterianum. By W. Thickins, Esq. 



In the last number of the ' Phytologist ' a new locality for Botry- 

 chium lunaria in Leicestershire is given, and as the plant is con- 

 sidered to grow but sparingly in Warwickshire also, it may perhaps 

 be worth mentioning that last year I found it abundantly a little be- 

 yond Moxhall, on some heathy ground on the right of the turnpike 

 road from Coleshill to Lichfield, and that a few weeks ago I discovered 

 it in a similar habitat near Coleshill Pool, perhaps the same locality 

 as that given in Newman, of which I was unconscious at the time. 

 Last year also I saw it in quantities, though in a very dwarf state, 

 growing with Viola lutea in some high pastures on Masson, near 

 Matlock, Derbyshire. I have found it, too, near Wirksworth in the 

 same county. 



In your March number, in a remark of yours on Sedum Forsterianum, 

 you say " You were not fortunate enough to meet with it at Barmouth, 

 where Mrs. Russell records its occurrence." 



The enclosed Sedum, which I take to be " Forsterianum," is from 

 a plant I brought from Barmouth in 1837, and have had in cultivation 

 ever since. It grew in a very dry, exposed situation, and only in a 

 similar one have I ever prevailed on it to flower. I am therefore 

 doubtful on reading your description of the different constitutions of
