the like, reference must be made to the Eeport, from which we 

 proceed to make a few extracts. 



" Sisymbrium altissimumlj. { = S. jMuiionicum J ncq.). A few 

 specimens are sent to record the great extension of area now 

 occupied by this species at St. Anno's-on-the-Sea, W. Lanes., 

 v.c. 60, July 15 and 19, 1912. When I first found this plant 

 at St. Anne's, ten years ago, it occurred on both sides of the 

 bridge over the railway in St. Thomas's Road, but it has now 

 spread over the district between Blackpool and Lytham. — 

 Charles Bailey." 



" Viola ' canina L. ' var. crassifoUa (Gronv.) x stagnina. 

 Woodwalton Fen, v.c. 29, Hunts., June 5, 1912. Named as 

 above by Mrs. Gregory, on the spot. A very beautiful violet, 

 when growing ; it showed clear traces of the parents, among 

 which it occurs, and formed large masses of flowering-stems, 

 visible from a considerable distance. — E. S. Marshall." 



" Sagina nivalis Fr. Ben Lawers (at 3000 ft.), Mid Perthsh., 

 v.c. 88, July, 1912. This is not a rare plant on the Breadalbane 

 Range, but it seems to be dying out on Ben Lawers. I do not 

 see it in the Eastern Ravine at all now. In the well-known 

 station on the Western Ravine the plants are only about ^-1 in. 

 in diameter. I do not know any botanist (or collector) who 

 knows the station these are taken from, though some of them are 

 evidently very old plants. — P. Ewing." 



" Er odium cicutarium L'Herit. var. glandulosum Bosch. 

 (1) On sand among bracken, Lihou Island, Guernsey. An extra- 

 ordinary plant, pointed out to me by Mr. Marquand ; straggling 

 over sand under bracken, especially at the mouth of rabbit 

 burrows. The branches were as much as 3 ft. long, with flowers 

 and green foliage only towards the tip. — W. C. Barton. (2) 

 Sandy Coast, Grand Havre, Guernsey, August 21, 1912. In 

 plenty on the sandy coast, this small-flowered form was growing 

 only in rosettes up to 12 in. diameter. I saw no plants develop- 

 ing long straggling branches as on Lihou Island and on Headon 

 Hill. — W. C. Barton. This is our usual small form of barren 

 sandy ground (heaths, &c.), which I suppose to come under type 

 { — a vulgatum Syme). The species is, as a rule, more or less 

 glandular.— E. S. M." 



" E. moschatum L'H6rit., var. (Ref. No. 38). Sandy coast, 

 Grand Havre, Guernsey, August 21, 1912. I have not seen an 

 authentic specimen of var. minor Rouy & Foucaud, but my 

 No. 38 agrees well with their description, and seems probable 

 from the habitat. I quote from Rouy & Foucaud: 'var. /i minor, 

 Nob. Plante de 8-12 cm. tr6s reduite dans toutes ses parties ; 

 feuilles a segments petits (3- 4 fois plus petits que dans le type), 

 ordinairement profondement incises ou subpinnatifides ; p6don- 

 cules 2-4 flores, plus courts que la feuille ; bee du fruit bien plus 

 grele, mais de meme longueur. Ca et la dans les pelouses 

 maritimes rases.' The variety or form is frequent along the 

 sandy coast from Grand Havre to Ler^e. Mr. Marquand told me 

 that, so far as he knew, it had been passed over as a dwarf form
