Risehow, also at Silloth : always, I think, the yellow-flowered type. 

 R. maritimus ; the only specimen I have seen in a growing state, 

 was a fine plant which I discovered in August last (1885), on the 

 north shore at Workington, behind the Lonsdale Dock. Sinapis 

 arvetisis grows on almost every rubbish heap. S. alba, on the 

 rubbish at Risehow ; once cultivated near Allonby ; scarce. 

 ^. nigra, railway siding near the Baths, Silloth (1868). Neither 

 of the two last-mentioned can fairly claim to be indigenous to 

 Cumberland. Brassica napus ; next to Sinapis arvetisis, the 

 commonest and most widely distributed of the charlocks. B. rapa, 

 here and there along the shore, plentiful on the Furness Railway 

 towards Coulderton. B. nwnensis, common along the coast; in 

 some places peculiarly abundant, as at Silloth, Flimby, and about 

 Siddick Junction. Sisymbrium officinale, another very common 

 species about hedgerows, borders of cultivated fields, rubbish 

 heaps, etc. S. sophia, on the ballast mounds about Silloth Dock 

 (1868). ^. alliaria, abundant near Maryport. 5'. patmoniciim, 

 a continental species of flix-weed, was observed lately growing 

 in a patch of waste ground between the Railway Station at 

 Maryport and the river Ellen. Cardamine amara, not strictly 

 a shore plant, though sometimes seen in moist situations ; in 

 swampy inland woods it is frequent enough. C. praietisis, 

 like the preceding, is an occupant of damp ground, edges of 

 brooks, etc. C. hirsiita, on old walls, especially if damp; abundant. 

 Arabis thaliana, on dry hedge-banks. Barbarea vulgaris, not 

 unfrequent about rubbish heaps, especially where the soil has but 

 recently been disturbed. Nasturtitun officinale, in brooks, common; 

 as at Bank End, near Maryport, and on St. Helen's farm, Work- 

 ington. N. terrestre appears upon heaps of rubbish on the beach 

 at Risehow, also upon the Maryport and Carlisle Railway, near 

 Oughterside Mill. Cochlearia officinalis, on moist rocks about 

 St. Bees, Parton, Harrington, etc. C. anglica, shore at St. Bees, and 

 at Workington. C. danica has been recorded from Coulderton, and 

 also from about Ravenglass ; I noticed it myself several years ago 

 a little to the south of Workington : but that station has disappeared, 

 and is now quite submerged by the inroads of the sea. Draba
