Of the numerous genera which have been contrived out 
of the Linnzean genus Euphorbia, the Pedilanthus of Necker 
is the only one which has been retained by M. Adrian de 
Jussieu, in his recent valuable work upon the Euphorbia- 
cee. From Euphorbia it is scarcely distinguishable except 
by the very curious and peculiar form of the involucrum. 
In addition to the synonyms usually cited to this plant, 
we observe, that Professor Link quotes the Euphorbia myr- 
tifolia of Linnzeus and Swartz, a wholly different plant, 
and a true Euphorbia. 
_ Our drawing was made at Mr. Colvill’s Nursery. The 
plant is a native of South America, and requires the pro- 
tection of a stove. We have had no opportunity of de- 
scribing it. '
