The Flora of Glamorgan. 23 



Brassica Rapa, Linn. Wild Turnip. 



No records. The third type recognised by the Editor as 

 occurring in the district remains unidentified. It is probably a 

 variety of the wild Navew. 



135. monensis, Muds. Dwarf Wallflower cabbage. Berwr inon. 

 Rare. Scarce. Native. Littoral. 



On the downs near Park and above Mincian Hole, three specimens 

 gathered in 1838 and 1839 by Mr. Moggridge. Rocks and down near 

 Pennard Castle. Gulch in Phyt. 1842. p. 106. At Nicholaston, 

 Gower. Woods in Phyt. 1850. p. 1060. Not common. Aberthaw. 

 J.S. I have looked for it so often that I feel sure it does not now 

 occur there. (Ed.) Inland at Merthyr Tydfil. Hooker's Flora. 

 Confirmed recently by F. 



136. Cheiranthus, Vill. 



No good records exist for this plant in a really wild state. The 

 record in L. W.D.Mat, refers doubtless to Mr. Moggridge's plants 

 mentioned under 135. In T.B., J.B.Supp., Port Taibot is given on 

 the authority of Marshall. This is a record of a plant probably 

 introduced with ballast. The species occurs regularly on the railway 

 embankments about Penarth Docks and between Penarth and 

 Cardiff ! ! It seeds and maintains itself for a time, but the number 

 of individuals is always few. 



137. Sinapioides, Roth. Black Mustard. Cedu du. 



Local. Abundant. Native. Littoral, viatical, and agrestal ! 



Frequent. Cardiff! Barry! etc. J.S. Lavernock Cliffs! Swan- 

 bridge ! V. Common round Barry ! B. This plant is common on 

 the Lias Cliffs from Penarth Head ! to Southerndown ! and 

 extends inland to cultivated fields, occasionally proving as trouble- 

 some a weed as Nos. 139 and 140. 



138. adpressa, Boiss. Hoary Mustard. 



This plant has little claim to inclusion. It used to be common as 

 a ballast plant about Cardiff, Penarth, and Barry. It has maintained 

 its hold at one spot near Barry I on sandy soil for at least six years, 

 seeding freely and producing fresh crops. 



139. 5inapistrum, Boiss. Charlock. C. gwyllt. 

 Common. Abundant. Native. Agrestal. 



140. alba, Boiss. White Mustard. 

 Local. Abundant. Native. Agrestal. 



Rare, Penarth, Southerndown. J.S. Between Penhill and 

 Canton, 1830. J.E. This plant is so common that the Editor doubts 

 whether it does not deserve to be recorded with the highest degree 

 of frequency for the habitats as well as for the individuals. No 

 records are, however, furnished by our correspondents, who possibly 

 have not learned to distinguish it from the Charlock with which it 

 is associated in our fields. It is often a common weed on the Lias 

 near the coast. It occurs from Penartli to Southerndown. In my 

 notes I find records for Penarth ! Sully ! Hayes ! Aberthaw ! Llantwit
