of L. alba sent me by Mr Chester from Northants in 1912." — G. C. 

 Druce. 



Gerastium tetrandrum, Curt., var, Burry Holm, v.-c. 41, June 

 1910. On this var. see Report 1910, p. 545. This supply is not quite 

 so characteristic as the former. — H. J. Riddelsdell. " A form I 

 think and not a variety of the polymorphic tetrandrum.'^ — G. C. Druce. 

 " This agrees very closely with my authentic sheet of C. suhtetra7idrum, 

 Murbeck (apud Baenitz, Herb. Europ., 1892) in habit, but is con- 

 siderably more glandular ; the species varies a great deal, and maritime 

 sands increase the glands." — E. S. Marshall. "Typical C. tetrandrum.^^ 

 — J. A. Wheldon. "Capsule short and straight, very unlike that of 

 var. dumense described in Journ. Bot. 17, 1913. The habit and size 

 is remarkable, and I have not seen so robust tetrandrum before. There 

 is a var. rnajus, Moris Fl. Sard, i., 267, 1837, but I do not know it." — 

 C. E. Salmon. 



Stellar-ia apetala, Ucria. Sandy places, St Martha's Hill, Guildford, 

 Surrey, v.-c. 17, April 1912. — J. Comber. "It exactly matches the 

 description in Rouy and Foucaud's FL de Fra'iice, iii., 230, of their 

 var. minor, of which S. Boroeana, Jord., is quoted as a synonym. Our 

 coast-plant is, as a rule, larger and more straggling." — E. S. Marshall. 



Stellaria neglecia, Weihe, var. umbrosa, Opiz. Particularly 

 luxuriant in hedgerows between Meole Brace and Pulley, Salop, 

 v.-c 40, May 1912. —J. C. Melvill. "My plants have hairy 

 peduncles and bluntly tubercled seeds." — G. C. Druce. "Yes; the 

 plant with glabrous calyx and pedicels, and acutely tubercled seeds, 

 which Opiz named S. umbrosa.^^ — E. S. Marshall. 



Arenaria teiiuifolia, L., 1 var. Wilbury Hill Gravel Pit, near 

 Hitchin, Herts, June 8, 1912. Seems to differ from the type in 

 having a glandular calyx, from var. laxa, Jord., in having 10 stamens, 

 and from var. hybrida, VilL, in its smooth peduncle.— J. E. Little. 

 " These plants are very similar to those sent from Minchinhampton 

 Common by Rev. H. J. Riddelsdell in 1909 (see Report 1909, 442), 

 and my remarks on that gathering apply equally to this. Note that 

 Boreau considers that hybrida should be glandular in the upper part, 

 and that the fruiting pedicels should be 'dresses etales.' " — C. E. 

 Salmon. "Yes, A. tenuifolia, L., Minuartia tenuifolia, Hiern." — 

 A. Thellung. 



Sagina nodosa, Fenzl, var. monilifera. Askham Ironworks, v.-c. 69. 

 Most of these plants were growing in the "rivet-holes" of flattened 

 boiler-plates, the others in sandy ground. All, save the smallest, were 

 produced naturally in these extremely draughty places. Very few
