May-June. 

 First recorded by Mr. W. Pamplin in PhTjt. v. 155, 1854. 



2. Ock. Marked by Mr. F. Walker in his list of plants seen about 



Marcham and Tubney. The district is a very probable one, 

 but I have as yet been unable to verify the record. 



3. Pang. Included in Mr. Pamplin's list of plants observed about 



Streatley and Goring, but as no specific locality is given, it is 

 uncertain whether the plant occurred in Berkshire or Oxford- 

 shire. But I have still greater doubts as to the correctness of 

 the identification, for at that time Mr. Pamplin had by no 

 means a critical knowledge of British plants, and his list con- 

 tains several misnomers, of which this is probably one. At 

 any rate the record needs verification. 

 5. Loddon. Included in the Wellington College List, but here 

 again I am afraid with insufficient foundation. Near Hurst, 

 1875, MehiU. Kather plentiful over a limited area of Biicher's 

 Green between Twyford and Maidenhead, 1892-6. 

 The heaths of the Kennet valley have been repeatedly searched by 

 me for this species without success. After the flowering is over it 

 becomes much less conspicuous ; but if it occurs tliere, and more 

 suitable localities could not be desired, it must be very local. 



T. subterranewn has been found in Surrey, Hants, and Wilts, in 

 Buckinghamshire, in which county Sir Jos. Banks gathered it at Salt 

 Hill about the year 1780, and in Oxfordshire, where it appears to be 

 now extinct. 



A decreasing species in the inland counties owing to cultivation.
