XOTES ON SEDUM 215 



much — but later, at Bremen, found it labelled as grown from 

 Mexican seed. With this clue, it was run down as S. mexicanum 

 Britton, a determination subsequently confirmed by specimens from 

 New York. How ^S*. mexicanum^ which was described in 1899 from 

 specimens raised in jSTew York from seed collected near Mexico City, 

 came to be in cultivation at Kew forty years ago, is not known. The 

 variety mentioned by Masters has no connection with S. mexicanum. 

 It is still frequently grown as aS*. sarmentosum variegatum or 

 S. carneum variegatum, but is in reality a sport of >S'. lineare Thunb., 

 a Japanese ally of 8. sarmentosum. 



S. WooDWABDii N. E. Brown in Kew Bull. 1912, 390. 



S. Woodwardii was described from a specimen sent to Kew by 

 the late Mr. Robert Woodward of Arley Castle, where the plant 

 appeared in a bed of seedlings of a Samhucus from the Rocky 

 Mountains. With these it had clearly no geographical affinity, as 

 it belonged to the Aizoon group of Sedum, which is confined to 

 N.E. and E. Asia, and it was probably a stray seedling from a bed a 

 few yards away, which contained seedlings of Chinese plants collected 

 by Wilson. Its proximity to >S'. Aizoon L. was recognized : — 

 "affinis S. Aizoo Linn., sed foliis obovatis obliquis obtuse dentatis et 

 C3miis majoribus laxioribusque differt." The t^^pe specimen at Kew 

 is poor ; but in a second one, apparently taken subsequently from a 

 root grown at Kew, the special characters quoted above have to a 

 great extent disappeared. By the kindness of Mr. Woodward, I 

 received from him a short time before his ultimely death fine speci- 

 mens of the plant, which appeared to be S. Aizoon grown large and 

 lax in rich soil and half shade. These, cultivated in an open border 

 with aS*. Aizoon forms, are now not separable from them, even by 

 characters of varietal value. S. Aizoon is a variable sj^ecies ; in 

 breadth and toothing of leaf, and size and denseness of inflorescence 

 considerable diversity exists ; S. Woodioardii is not an extreme form 

 as regards any of these characters. 



SOME BRAZILIAN PLANTS. 

 By R. C. Davie, M.A., D.Sc. 



The plants named in this list were collected during a visit to the 

 States of Rio de Janeiro and Sao Paulo in July, August and SejD- 

 tember, 1914. The object of the visit, in which I was aided by a 

 Royal Society (Government) Grant, was the collection of flowers of 

 the native Legiitninosce. 



No attempt was made to collect and dry specimens of plants 

 representative of the floras of the districts visited, but interesting 

 plants which happened to be noticed during the search for leguminous 

 flowers were gathered from time to time. Among them were various 

 species which are poorly represented in British herbaria ; two prove to 

 be new. As far as can be ascertained, several of the species have 

 not previously been recorded for the districts in which I found them. 



An interesting point which has appeared during the working up of
