Scand. i. 195 (1846). Occurs in the Isle of Wight, on Freshwater Downs and Catherine's Cliff; Moreton, Warwick- shire, F. Townsend; and in Aberdeenshire, Marshall. E. LATiFOLiA Pursh, Fl. Am. SeiJt. ii. 430, which is figured in Flora Danica, n. 2910, is recorded from " Cumberland (H. Kern.) (Taylor; H. Hofni.),'" but no more precise statement of its occur- rence in Britain is given. E. FouLAENSis Towns, in sched. is the form found by Mr. Beeby in Foula, Unst, &c., in the Shetland group ; it also occurs in the Faroe Islands. E. GRACILIS Fries, Fl. Halland. 104 (1818) as a var. and as a species in the Summa Veg. Scand. i. 198 (1846). Throughout the monograph Dr. Wettstein follows the continental school of nomen- clature which tries to ensure the permanency of the trivial name. The oldest name which should be accepted, according to our British plan, is E. rnicrantha Keichb. Fl. Germ. Exc. 358 (1831-2). This plant is recorded for Aberdeen, Inverness, and Argyll, on the authority of specimens from F. Townsend and Nicholson. The writer has it from Ross, Perth, Oxford, and Berkshire. E. ScoTTiCA Wettstein = E. pahidosa Towns. Journ. Bot. 161 (1891), not of E. Brown. This plant is only recorded from Braemar, where it was originally found by Mr. F. Townsend growing in a marshy place with sedges. It also occurs in Argyll and Westerness. E. RosTKoviANA Haync, Arz7i. ix. t. 7 (1823), is figured in Syme, E. B. 991. It is given from Buxton, Derbyshire; Rosthwaite, Cum- berland ; Oban, Argyll, by F. Townsend ; and for Caithness by Linton. E. Kerneri Wettstein in Engler & Prantl, Nat. Fflanz. iv. 101 (1893), is given for Chelsham, Croydon, by Bennett. Several hybrids are described, but of these only one is recorded from Britain, namely, E. Rostkoviana x nemorosa Towns. = E. glanduligera Wettst., which was found at Buxton by Mr. Townsend. There are fourteen plates, two of which are devoted to the histology and morphology of the genus, four others contain nearly 500 figures of parts of the flower, calyx, and bracts, while the remainder illustrate the various species from reproduced photographs of herbarium specimens. Four charts show the geographical distri- bution, &c., of some of the species of the genus. This work can be cordially recommended to the systematist. G. Claridge Druce. A Manual of Botany. By J.
