confess that, however pleased in finding such a rarity, I could not help 

 remembering how many others of the genus Allium are liable to sus- 

 picion as natives, and it did occur to me that possibly here was the true 

 old Leek of Wales, in former times probably employed as a pottage 

 herb by the occupiers of that fortified headland. In Ireland I have seen 

 Allium Babingtonii only where associated with, or in the vicinity of, 

 ruins or cultivation. Similarly, at Killarney, Allium Scorodofirasum 

 is too closely connected with the rides known as the " Monks' Walks," 

 and in Ireland has only one other very restricted station, near Cork. 

 So that, in all three cases, we are probably dealing with relics of very 

 ancient cultivation, dating from the time of the early Celts or Britons, to 

 which it is scarcely an objection that the native or original habitat of 

 Allium Babingtonii has not yet been ascertained.

Of these Cicendia, frequent also on moist heathy ground to the west 

 of St. David's, finds here its northern limit in Wales. Aira uliginosa, 

 plentiful in many places round Dowrog Pool, is new to West Britain. 

 Alisma repens, with its large flowers and often growing in the^water, 

 might easily be mistaken for A. natans. Littorella new to Pembroke- 

 shire. 



Agrimonia odorata occurs in one place by the roadside towards 

 St. Justinian's Chapel. Erodium moschatum is frequent, and so are 

 Mentha rotundifolia and Calamintha officinalis in the neighbour- 

 hood of the town.
