BOME ^-^EW SPECIES OF SEDUM 30 



One of the species described below is very widely spread in 

 gardens, under the name of one or other of its allies, from Japan 

 on the east to Canada on the west. The remainder are more or less 

 recent introductions into cultivation, for the opportunity of growing 

 and studying which I am indebted to the Directors of the Botanic 

 Gardens at Edinburgh, New York, and Sapporo, to Dr. J. N. Rose, 

 of the Smithsonian Institution, to Mr. H. J. Elwes, F.R.S., and to 

 Mr. E. A. Bowles, M.A, The descriptions have been drawn up from 

 living material, and most of the plants have been studied during 

 several successive seasons — a necessary precaution in a group where 

 so much variability exists, and where immature plants are so mis- 

 leading. The plants will be figured later in the Journal of the Boyal 

 Horticultural Society, 



I should like to record my indebtedness to Mr. W. W. Smith for 

 assistance in the preparation of this paper.

1 found this remarkable plant in the garden of Mr. H. J. Elwes, 

 who unfortunately cannot now remember whence it was obtained. , 

 It is certainly Asiatic, probably Tibetan, Mongolian, or Chinese, 

 and very likely came from seed brought home by one of the 

 recent botanical explorers of that part of Asia. A very distinct 

 species, and much the tallest of the Rhodiolas. The male ]:)lant is 

 as yet unknown. By an oversight I neglected to note the characters 

 of the hypogynous scales. This omission Avill be recti hed in due 

 com-se in the Journal of the Boyal Horticultural Socieiy.
