438 EUPHORBIACEAE 



Denizen. Pascual. Grassy slopes on the Chalk. Very rare. P. 



July-August. 

 First recorded by Mr. F. Tufnail in the Flora of Oxfordshire, 1886. 



3. Pang. On an open grassy slope beneath Sulham Wood, Tufnail. 



It still occurs there, but I can make no suggestion as to its 

 possible introduction. 



4. Kennet. Brimpton. Sulhampstead Park, Weaver. 



5. Loddon. Included in the JVell. Coll. List, but it is to be feared 



not from a Berkshire locality. The Eev. C. W. Penny does 

 not know of its occurrence in the county. 

 The plant is recorded for Oxfordshire and Hampshire.

Vai". RETUSA (DC. Fi. Fr. 358, as a species 



Apparently rare. I have only noticed it in a field between Egrove 

 and Wantage, whence I distributed specimens through the Rot. Exch. 

 Club in 1893. 



Mr. Tufnail tells me he gathered fine specimens at Wokefield. 



It differs chiefly in its mucronate and truncate leaves ; in the type 

 they are acute. A biennial form also occurs occasionally.
