 EUPHORBIA, Linn. Gen. n. 536 {Tithymalus, Tournefort, Inst. t.i8V 

 E. helioscopia, Linn. Sp. PI. 459 (1753). Sun Spurge. 



Helioscopios, Pliny. Tithijmalus Helioscopius, Ger. 401.

 Phaen. Bot. n. 368, 1840. 

 It occurs in all the bordering counties. 



[E. PLATTPHYLLos, Liiin. Sp. PI. 460 (1753). Syme, E. B. viii. lOO, t. 1255. 



Common in cornfields, J. Lousley in RusselVs Cat. 1839. An error ; either 

 E. Helioscopia or E. exigua was the plant seen. 



Mr. Britten states that the plant of the Wellington College List was 

 Millegrana. A curious error. 



E. platyphyllos is a plant we might expect in Berkshire, since it is recorded 

 for all the bordering counties, although I have never met with it in Oxford- 

 shire. It is either a decreasing species or some of the older records were 

 mistakes.]

 and widely distributed. P. April-July. A conspicuous feature 

 in our woodland scenery, and too general in our woodlands to need 

 a list of localities.

 It occurs with a very varying amount of pubescence ; the extreme 

 states are very different.
