" S. peregrinum Ledeb. {fide C. Bucknall). By cart track 

 between Manor Farm and King's Hedges Koad, Chesterton, 

 Cambs., v.c. 27, June 7, 1912. — G. Goode. S. 'peregrinum Ledeb., 

 when growing on the banks of streams, is a tail, kixuriant plant, 

 with iiowers rose-coloured in bud, then bright blue, the stem 

 without wings, and l^earing abundant fruit. When growing in 

 dry localities, the iiowers remain rose-coloured or are only 

 partially blue, and the entire plant is not so well developed as 

 when growing in moister situations." 



" This species forms a series of hybrids with the white and 

 purple-flowered varieties of S. officinale, which have been described 

 by the writer in the Journal of Botany, vol. 1. p. 332 (1912). 

 These are distinguished by the more or less winged stem, by the 

 colour of the flowers, which are white, rose-coloured, bluish or 

 purple, always changing to a cinereous blue in the dried plant, 

 and by the fruit being sparingly produced. 



" Typical S. pcregrinmn, as well as some of its hybrids, has 

 often been named S. patens Sibth., but the latter is probably only 

 S. officinale y&v. j^urjjureuni with undeveloped fruit, and the calyx- 

 lobes, in consequence, spreading after the flowering instead of 

 being connivent over the nutlets, as is the case when they are well 

 developed. S. peregrinum has also been confused with S. asperum 

 Lepech. (<S'. asperrimuvi Donn and M.B.), which, in Britain, is a 

 much rarer plant. It is distinguished by the small calyx with 

 obtuse segments, the calyx in S. peregrinum being generally con- 

 siderably larger, with acute lanceolate segments. With regard to 

 the clothing of hairs and prickles, and in other characters, both 

 species are variable, and they are often difficult to separate except 

 by the above-mentioned characters of the calyx ; and when, owing 

 to conditions of climate or situation, the flowers are imperfectly 

 developed, even these characters are liable to be deceptive. It is 

 probable that intermediates, and possibly hybrids, occur, and that 

 they are sometimes the cause of the difficulty in the accurate 

 determination of these plants. 



" Ledebour, in the Flora Bossica, has well distinguished the 

 two species, and complete descriptions, with remarks on the forms 

 which occur both in the wild and naturalised state, will be found in 

 the writer's 'Revision of the Genus Symphytum' in the Journal of 

 the Linnean Society (Botany) xli. Dec. 1913. — Cedbic Bucknall." 



" Veronica hyhrida L. Riverside rock, under Leigh Woods, 

 Bristol, N. Somerset, v.-c. 6, July 6, 1912. New county record. 

 It is only this past summer that a few plants have become 

 established on the Somerset side of the Avon. — Ida M. Roper. " 



" Ghenopodium leptopliyllum Nutt. {fide G. C. Druce). Waste 

 heap of London rubbish north of Welwyn Tunnel, Herts., v.-c. 20; 

 Sept., Oct. and Nov. 1912. Habit very different from G. album, 

 and possibly a distinct species. — J. E. Little. This is Clicno- 

 podimn album var. leptophyllum Moquin in DC. Prodr. xiii. part ii. 

 71 (1849), naturalised or adventitious in Europe from North 

 America. The name ' G. leptophyllum Nuttall,' often seen in 

 systematic works, is merely a name cited in synonymy by
