resuscitated Echeveria, which as defined by him, includes 
some sixty species, mostly Mexican, though some occur 
in Central America, a few in South America, and one is 
met with in Texas. It has to be noted, however, that 
_while he accepts the view of Decandolle in preference 
to that of Bentham and Hooker, the character on which 
Dr. Rose lays greatest stress is that pointed out in the 
Genera Plantarum ; Echeveria, Rose, as contrasted with 
Lcheveria, DC., must consequently be held to include 
several South African plants with a pentagonal corolla. 
This suggests consequences which need not be discussed 
in connection with /. setosa, the species now figured, 
which has, so far, only received a name in the genus 
Echeveria. This plant, readily distinguished from all its 
congeners by its setose leaves, was discovered in 1907 by 
Dr. C. A. Purpus on the Cerro de la Yerba, near San Luis 
Tultitlanapa, Puebla, South Mexico. Plants were pre- 
sented to Kew in 1910 by Dr. Britton, New York Botanic 
Garden, and in 1912 another was acquired from Messrs, 
Haage and Schmidt, Erfurt. From the latter, which 
flowered in 1914, our figure has been prepared ; two 
smaller leaves have been added to the plate from a 
plant presented by Dr. Britton. In England £. setosa 
can only be grown under greenhouse conditions. It 
flowers regularly and produces offsets freely.
