South Russia, Transcaspia, Italy, and Turkish Armenia. Mr Pear- 

 sail pointed out that its most characteristic feature is presented by 

 the narrow pale band running longitudinally round the middle of the 

 ripe seeds. The torulose character of the ripe fruit is manifest. — 

 C. Bailey. " Dr Thellung has kindly determined this to be the 

 B. elonyata Ehrh., sub-sp. joersica (Boiss. et Hohen.). It is also the 

 B. armoracioides Czern." — G. C. Druce. 



Brassica elo7igata Ehrh. [Kef. No. 371]. Railway ballast, 

 Cavendish Dock, Barrow-in-Furness, v.-c. 69 b., August 29, 1913. 

 This E. European species is so very polymorphic that I refer my 

 specimens to it with some ditfidence. Book descriptions give " lower 

 Is. lyrate, upper Is. toothed, long pods on short pedicels." My plants 

 have none of these characters. They are large (2-3 ft.), much 

 branched, twiggy, and extremely brittle. Leaves very scarce, all 

 entire, narrowly and bluntly lanceolate, possibly the var. iiitegrifolia 

 Boiss. No lyrate radical Is. occur. The pods are markedly torulose, 

 but can scarcely be termed " beaked." The seeds should be diagnostic 

 — each has a well-marked narrow yellow band running completely 

 round its longer circumference. — W. H. Pearsall. " The pods look 

 right for this species, but one would have liked a few leaves." — C. E. 

 Salmon. "This also is the sub-sp. persica.'' — G. C. Druce. 



Bursa pastoris Weber, var. integrifolia (Lej. et Court.). Walton, 

 South Lanes. (59), Aug. 1, 1913. Growing amongst potatoes. — J. A. 

 Wheldon. "Yes." — G. C. Druce. "I have received two sheets of 

 this gathering; (1) judging by the shape of the capsules, is a mixture 

 of two dissimilar forms ; (2) is a small form of var. bifida Mott, 

 showing some approach towards var. ruhellceformis Mott." — C. E. 

 Britton. 



Capsella Bursa-pastoris Medic, var. bifida Mott. [Ref. No. 580.] 

 Lower Morden, Surrey, May 6, 1912. This is one of the most 

 distinct forms of Capsella, and matches exactly an authentic plant of 

 Mott lent me by Mr Jackson. It will be noticed that there is a 

 tendency to bear two forms of capsules, but, as the shorter and 

 broader form is on the primary stem, this difference is probably due 

 to a variation in the vigour of the plant's vitality dependent on age, 

 and plants of Mott's gathering show a similar peculiarity. Whether 

 this var. is identical with the bifida, of Orepin is uncertain. — C. E. 

 Britton. 



Capsella agrestis Jord. [Ref. No. 573.] Molesey Hurst, Surrey, 

 May 5, 1912. This plant agrees well with the description of C. 

 agrestis in Jordan's Diagnoses, p. 339, and, moreover, is identical 

 with continental plants so labelled in Herb. Mus. Brit. Whilst the 

 London Catalogue ignores all varieties of Capsella Bursa-pastoris, Mi*
