RECENT PUBLICATIONS. 

 British Violets : a Monograph. Mrs E. Gregory, pp. xxiii., 

 108, 34 ill., Heffer & Sons, Cambridge, 1912. In this very 

 interesting Monograph of a very difficult genus, our Violet 

 referee, Mrs Gregory, has described the 12 species of British 

 Violets with the very numerous varieties and hybrids in a clear and 

 readable work which cannot fail to stimulate the study of the group. 

 In last Report, pp. 154-5, the additions were briefly alluded to. They 

 include V. odorata var. praecox Greg., a dark-flowered plant from 

 Devon and Somerset ; var. sulfurea (Cariot) Greg., with apricot 

 coloured flowers from Hereford already in the List, which perhaps 

 should be a sub-var. rather than a variety ; the hybrid V. collina 

 Bess, from Surrey and Devon, is V. hirta x odorata, but differing both 

 from permixta and sepincola ; V. hirta var. variegata from Wych- 

 wood, Oxon, differing from the type in its more angular capsule, the 

 angles clothed with long hairs, and its beautifully variegated flowers ; 

 Viola epipsila x palustris, a hybrid from Dartmoor, Viola Riviniana 

 var. diversa Greg. (See Report 496, 1910); var. pseudo-mirabilis (see 

 Riibel in New Phyt xi., 55, 1912). V. canina x silvatica from 

 Innisfallen Island, Co. Kerry ; the true V. rupestris Schmidt from 

 Durham ; V. -canina var. sabulosa Reichb., Codicote Heath, Herts ; 

 var. lanceolata Mart.-Donos, Menmarsh, Oxford ; near Warham, Nor- 

 folk ; Yate Lower Common, Gloster ; and above Quenvais, Jersey ; 

 var. lucorum Reichb., Wood Walton, Hunts ; V. canina x lactea 

 var. pumiliformis Greg., Chailey Common, Sussex, are also among the 

 many interesting plants described, and for which British botanists 

 are indebted. The book is well printed, and the illustrations 

 excellent.
