FOSSIL EUPHORBIACEAE, WITH A NOTE ON 

 SAURURACEAE * 



By T. D. a. Cockerell 



Up to the present time, no Euphorbiaceae have been described 

 from the American Tertiaries, although from their present 

 abundance and wide distribution there can be no doubt that they 

 have long existed on this continent. Most of the plant-bearing 

 strata are very poor in herbaceous forms, but Florissant is more 

 fortunate in this respect, and has already yielded us a number of 

 low-growing genera not elsewhere known fossil. Among the 

 recently gathered materials I have been glad to find a couple of 

 species which appear to be certainly Euphorbiaceous. 



Acalypha myricina sp. nov. 



Leaf lanceolate, the blade about 22 mm. long and 8 broad, on 

 a short curved petiole ; general form very much as in A.gracile?is 

 Gray ; surface densely glandular-pitted ; margin with very short 

 blunt dark-colored gland-teeth ; three prominent nervures, run- 

 ning nearly parallel. The figure shows the details better than 

 they can be described.
