 T.H.T. Barry District. D. and M.A.D. Monknash. Miss D. The 

 plant is so plentiful on several parts of the coast as to be regularly 

 collected in hard winters for use as a vegetable. It occurs in great 

 profusion, as Storrie says, from Barry to Southerndown, the rotten 

 Lias cliffs, with tlieir alternating bands of clayey shale and limestone 

 suiting it admirably. Watson classes it as a denizen, but he had 

 never seen this plant on our coasts. It is almost certainly a true 

 native with us, or at any rate indistinguishable from one. There are 

 no records from the Western half of the County, where the Lias 

 rocks do not occur. 



The next three species constitute a group of special difficulty 

 even to those who have paid most attention to them. The Editor 

 has grown one of the forms for two generations, and recognised three 

 as occurring in the district. The nomenclature of the London 

 Catalogue is, upon the whole, less satisfactory than that of Syme in 

 English Botany. We shall therefore adhere to the latter. The 

 aggregate species is named by Syme, B. polymorpha, and he reduces 

 the three Linnaean species B. Napus, B. campestris. and B. Rapa to 

 the rank of sub-species. Whether this grouping will stand the test 

 of experimental culture remains to be seen ; it will in the meantime 

 best serve our purposes. 



Brassica polymorpha: — aggregate species. 



Most of the records are recognisable as distinctly referring to 

 this aggregate species. It is recorded from most of the district, e.g. 

 Merthyr, Aberdare, Hirwain, Coedriglan, Sully. Sometimes, however, 

 it is confused with altogether different species, as when it is referred 

 to as growing in " fields everywhere." 



Brassica Napus, Linn. Rape. 



Local. Frequent. Colonist. Viatical and agrestal. 



Kilvey Hill, Common. Gutchin Phyt. 1842. p. 106. Frequent. 

 Llandaff, etc. J.S. and T.H.T. Mr. Storrie, however, does not 

 distinguish specifically between the wild turnip and the rape. 

 Plentiful around Barry. B. Lavernock. M.A.D. Cathays Park, 

 Cardiff ! in 1905 and 1906 along margins of new roads. 



Brassica campestris, Linn. Wild Navew, the Swedish Turnip 



being a cultivated variety. Meipen yd. 

 Glamorgan name : — Erfinen wyllt. 

 Local. Frequent. Colonist. Agrestal and viatical. 



The plant is often found along the margins of reens and streams 

 in the Vale of Glamorgan. It is not only the commonest of the three 

 sub-species, but in my opinion, the only one which can be said to 

 really maintain itself in the wild condition. Most of the records 

 under the aggregate species no doubt apply to this form. Dinas
