Sent by Dr. J. N. Rose from Washington to the Ilo3^al Horti- 

 'cultural Society under the designation ''Secha?i, no. 0(3.10." Dr. Rose 

 informs me that it was collected at Amecameca, Mexico, by C. A. 

 Purpus, in January 1906, no. 108. It is quite distinct from any of 

 the other species of the difficult sub-shrubby flat-leaved section of the 

 Mexican Se(Ju)?i-^ord. 



SUPPLEMENTARY NOTES TO THE HERTS FLORA. 

 Br J. E. Little, M.A. 



The following paper presents a selection of records, chiefly in the 

 north of the county, from 1890-1916, of species for which Fryor's 

 information was less complete, of some segregates determined in most 

 cases by specialists since his time, and of some varieties hitherto so 

 far as I am aware scantily or not at all recorded. The aliens wliicli 

 have become established are included, but a considerable number of 

 casuals has been excluded. Where I have thought that a plant 

 already admitted to the British Flora is in these records a casual or a 

 weed of cultivation, I have added a note. Where no authority is 

 cited, I am responsible for the record. 



The subspecies of Draha verna L. are given, with some hesitation, 

 for what they are worth. It seems quite possible that the adoption 

 of a classification based upon simple or branched hairs is a wrong 

 J'undamentum divisionis. In an attempt to group various forms of 

 Sagina afetala Ard., by the position and nature of the hairs, their 

 real relation appeared to be rather obscured than assisted by the 

 adoption of this method. If this be true of Draha verna, the present 

 •confusion of its sub-divisions is explained.
