Barbarea praecox, Br. (1). Waste ground, Stapletonr 

 Bristol. June 19, 1897. (2). St. Vincent's Rocks, Clifton, 

 Bristol. June 2, 1900.— J. W. White. Correct; possibly this, 

 like many other species well-established on St. Vincent's Rocks 

 has escaped from gardens overlooking the Avon gorge. —

Sisymhrium Irio, L. Waste ground, West Dock Reservation,. 

 Hull, E. Yorks, v.c. 61, July, 1900.— C. Waterfall. No, 

 S. Columns Jacq. This species is apparently becoming more 

 common every year about our large towns. A very different 

 plant to 5. Irio, L.— S.T.D.

— H. P. Reader. Camelina foetida, Fr. and C. sativa, Crantz, 

 are probably not distinguishable as species, but when typical 

 have the following differences : — C. fcptida has a short lax 

 raceme, its silicules are on spreading peduncles, have obversely 

 cordate septa, and soft valves, and its seeds are three-lobed ; 

 C. sativa has an elongate raceme, ascending peduncles, obovate 

 septa, hard valves, and cylindric seeds. Mr. Hilton's specimens 

 approach the former, but have the firm valves of sativa and 

 scarcely cordate septa. Of Mr. Waterfall's specimens, one 

 sheet submitted to me carries two forms neither of which has 

 ripe fruit, the second agrees with Mr. Hilton's specimens. 

 Mr. Reader's specimens are also immature, but are probably 

 fairly typical C. sativa. — S.T.D. 



Lepidium ritderale, Linn. Dry bank, Aylestone, Leicester.. 

 — Aug., 1900. This, a few years ago, was only found in one 

 locality ; now it has become more plentiful in that locality, and 

 a fresh one is recorded on the opposite side of the town. — 

 W. Bell. Correct. This rapid spreading of L. ruderale is 

 occurring in many of the larger towns. About London it is 

 already one of the commonest waste-ground weeds. — S.T.D. 



Thlaspi alpestre, L. var. virens (Jord.), Matlock, Derbyshire, 

 May, 26, 1900.— D. T. Playfair. Yes, virens.— E. S. & C. E. S.
