 Nearly all the records of H. vukjatum in Berkshire probably belong 



to this plant, which also occurs in Hants, near Enborne ; in Bucks, 



near Taplow ; in Surrey, and in Oxfordshire. 



If this plant is retained as a distinct species from H. sciaphilum of Diclit! 

 in Deutsche Bot. Monatsb. ii. (1884) 59, the name will have to be altered 

 from sciaxjliilum to Uechtritzianum. There is also a H. Sciaphilum of Jordan, 

 which is said to be synonymous with H. vulgatum.

 The plants recorded as H. tridentaium in the foregoing list in many 

 cases doubtless refer to the var. scahrescens. Those inserted on my own 

 authority were named H. tridentaium some time since by Mr, Hanbury. 

 H. rigidum does not appear to be recorded for E. Gloucestershire or 

 Bucks.
