EUPHORBIA, spurge 
[M: incl. POINSETTIA] (Webster, 1967) 
(see also CHAMAESYCE) 
(1979) as synonyms of E. pubentissima Michaux, but all 
Missouri collections earlier attributed to these varieties 
were redetermined by Huft as E. corollata and he does 
not show E. pubentissima ing in the state; 
most other authors, including Richardson et al. (1987) 
and Smith (1988) have not accepted any of these 
entities as separable from the morphologically variable 
E. corollata, a view tentatively accepted here), p. 989
