 soil, wall-tops, &c. Locally common, and too frequent to need 

 detailed localities. A. February-August.

Plants with cleistogamous flowers are not tinfrequent, as on Boar's 

 Hill, F. T. Bichards : at Frilford, Frilsham, Twyford, Mortimer, &c.

April-August. 

 First certain record. Medmenham, J5nY^en*s Cow^r. 187 1. Mr. Pamplin's 

 record of L, purpureum, var. incision, in PJnjt v. (1854) 156, was 

 probably L. purpureum, var. decipiens, which still occurs about 

 Pangbourn.

 Basset. In fields between Wittenham and Didcot. In fields 

 near Wootton.

5. Loddon. Near Medmenham Ferry, Britten. Early Rise, Tufnail.

 Maidenhead. 

 L. hybridum, which is not a hybrid, notwithstanding its name, has 

 been recorded for all the bordering counties except Buckinghamshire 

 [where I have seen it near Slough] and E. Gloucestershire. 



The Maidenhead plant has much of the aspect of L. purpureum, and 

 the Rev. E. F. Linton thought it might be L. hyhridum x purpureum, but 

 it has perfect seeds.
