XV. SEDUM CARNEGIEI, A NEW SPECIES OF THE 



FAMILY CRASSULACEiE FROM THE HERBARIUM 



OF THE CARNEGIE MUSEUM. 



By Raymond Hamet. 



On the frontier of Thibet Captain H. J. Walton discovered an 

 extremely interesting new species of the family Crassulacece, the place 

 of which in the botanical world is as yet unknown, the type of the 

 species being found in the Herbarium of the Carnegie Museum. I 

 am happy to dedicate this plant to Mr. Carnegie as proof of my 

 sincere admiration.
