278 EEPORT OF THE BOTANICAL EXCHANGE CLUB. 



Belphinmm consoUda, '< Linn.," Reich. *' Penzance Green, Corn- 

 wall, Aug.-Sept., 1872. About a dozen plants." — B. Tuckeb, 

 M.A. True D. consolida of the Continental botanists, but doubtless 

 a casual in Cornwall, as it has proved to be in Jersey, where no one 

 has found it of late years.— J. T. Eoswell. 



Brassica Rapa, L. (<?. Briggsii, Lon. Cat., ed. 7.) " In arable land 

 near St. German's Beacon, E. Cornwall, 26th Aug., 1874."— T. 

 R. Aecher Briggs. "Miss Payne sends specimens from "Weymouth, 

 Dorset, under the name of Brassica * Napus,^ collected in July, 1872, 

 which I believe to be the same as Mr. Briggs's annual form of the 

 wild turnip, which in the last edition of the London Catalogue is 

 named by Mr. Watson ' Briggsii.'' The members of the Club will 

 scarcely require to be told that the h. sylvestris immediately pre- 

 ceding it in the London Catalogue is the biennial form of wild turnip 

 so common along the banks of the Thames above London." — John T. 

 Boswell. 



CochUaria anglica, Huds. " Of this plant there are two forms, 

 apparently widely separated when seen apart, but so connected by 

 intennediate links that it is difficult to say where the line ought to be 

 drawn between them. The common form in the south-east of England 

 is certainly the var. gemina of the Rev. F. Hort, which I think was 

 lounded originally on specimens collected near Chepstow ; but it is the 

 common form along the estuary of the Thames and in the Isle of 

 Wight. In this the root-leaves are attenuated at the base, the fruit 

 very large, sometimes half an inch long, oval, more or less tending 

 towards obovate, and inflated on the underside on each side of the 

 narrow septum, which thus appears to be situated in a tolerably deep 

 furrow. The other form from the I^orth of England I propose to call 

 var. Hortii, as it appears to be the plant which the Rev. F. Hort 

 considered the type of the species. Which is really the more widely 

 distributed form I am unable to say, but the few Continental specimens 

 of C. anglica which I have seen certainly belong to var. Hortii, such 

 as those published in ' Wirtgen's Herb. Plant, select. Fl. Rhenanae.' 

 What I consider the type of this variety is sent by Mr. Robert Brown, 

 from the * muddy shore of the river Mersey, Birkenhead, Cheshire, 

 July, 1873,' and has also been sent to the Club by Mr. J. Harbord 

 Lewi's. The radical leaves are oval, tending towards ovate rather 

 than obovate, abrupt or rounded at the base, and the pods consider- 

 ably shorter, often not more than a quarter of an inch long, broader 

 in proportion than var. gemina, and having the broadest part in the 

 middle, and not at all towards the apex. A more largely developed 

 state of what seems to me the same as this variety is sent by the Rev. 

 Augustin Ley, from the tidal banks of the Wye, Tintern, Monmouth- 

 shire, consequently not far from Mr. Hort's station for var. gemina, 

 to which I think by far the greater number of the specimens of 

 Cochlear ia anglica, sent by Mr. Ley, must be referred ; but the pod and 

 leaves require to be examined in a fresh state, and it is to be hoped 

 that members of the Club will make notes as to the correlation of the 

 shape of the root-leaves with that of the pod, and with the apparent 

 depth of the furrow upon the latter, whicli cannot be properly observed 

 in dried specimens. Mr. T. R. Archer Briggs sends a series of Coch- 

 learias from the neighbourhood of Plymouth, which appear to connect
