In sandy and gravelly soil. Frequent along the Hudson river in 

 Albany county, and apparently also across the State south of the 

 Adirondack region. 



Doctor Greene (Pittonia, 3: p. 207) in renaming E. hirsuta 

 W^iegand, does not state which of the three species of Euphorbia 

 described by Rafinesque, he considered the same as this species, 

 merely remarking that the name was preoccupied. Of the three 

 species referred to, only E. 1 i 1 1 o r a 1 i s appears to be preoccupied 

 name, and that, described as possessing pubescent capsules, can 

 not be this species. E. s u p i n a Raf. is clearly a synonym of 

 E. maculata L., and E. litt oralis Raf. is a fairly good 

 description of what is now called E. h u m i s t r a t a . E. vermi- 

 culata is well described and can only apply to this species which 

 has glabrous capsules, along with the other characters which he 

 mentions. It is common along the Hudson river, the upper portion 

 of which is the type locality of the plant described by Rafinesque. 



Rafinesque's description reads as follows : 



21 Sp Euphorbia vermiculata Raf. Upright, nearly 

 dichotomous, pilose : leaves opposite, shortly petiolated, oblong acute 

 acuminate serrate trinerved, base oblique, thin, A'ermiculate — dotted : 

 flowers solitary in the dichotomies ]ieduncled upright, perianthe 

 cnmpanulated fourcleft, sepals ovate entire, capsules smooth. — Obs. 

 Found in August. 1816, near Sandyhill and Glens Falls. State of 

 New York, in fields. Small annual plant, flowers reddish : the 

 verm.icular transparent dots of the leaves are very remarkable.
