SPECIES NON SATIS NOT^E. 



Pedilanthus Houlletii Baill. Adansonia, 1:341. 1861. 



The description of this species was drawn from a plant cultivated

 A species credited to Mexico but with insufficient description to 

 satisfactorily establish its status.

 appendix a concave, glandular disk upon the middle of the dorsum; 

 peduncle jointed and bearing two leafy bracts; fruiting pedicel strictly

This genus apparently joins Pedilanthus toEuphorbiodendron,to the
