Wry widespread in cultivation, being found in gardens all over 

 Euro])e. westward to Canada and eastward to Japan : most fre- 

 quently under the name kamtschaticinn, but sometimes as Aizoon, 

 ^(Iskjiunum, hyhridvui, etc., to all of which it is allied, but from 

 which it can be distinguished at a glance. In herbaria it appears to 

 be very rare. The only exam]jle in the British Museum Herbarium 

 helps "to define its native distribution. It is a small specimen from 

 Hance's Herbarium, collected as aS'. kamtschaticum at Hakodate, 

 .lapan, by Maximowicz in 1801 ; so that the plant belongs to N.E. 

 Asia, as would be expected from its affinities. The only dried 



specimen at Kew is from the gardens, labelled " ^edinn , Kew 



(lardens, Sept. .18, 1901. Legit N. E. Brown,'' showing that that 

 botanist, who paid much attention to tlie Kew Sedums, had noticed 

 its peculiar characters. 



Plants received from a dozen different countries have been grown 

 in my own garden, and show that the plant is very constant in its 

 characters, though belonging to a group several species of which 

 display considerable variation ; but this constancy may be due to all 

 or most of the j)lants found in cultivation having had a common 

 origin. Its very wide distribution in gardens points to early 

 introduction. 



Named in memory of Canon H. X. Ellacombe, keenest of gar- 

 deners and kindest of friends, at whose suggestion 1 undertook a 

 revision of the cultivated Sedums.

 on roofs and rocks (especially the former) at and about Siku, Kansu, 

 (3400-8000 feet (Farrer, no." WMV). Ai)paivntly not of easy culture;
