BOOK-NOTES, NEWS, dc. The Messrs. Linton are about to issue a set of British Hieracia, which should be of service in determining these critical plants. The set will be issued in four or more fascicles, of not less than twenty- five numbers each ; price &1 for each fascicle (carriage free). The first two fascicles are in an advanced state of preparation, and the remainder will be ready to send out at intervals of a year or more. Each number will commonly contain a wild and a cultivated speci- men ; or wild only, if such can be procured to represent the species well ; or cultivated only, if the wild are not procured in sufficient quantity. Cultivated specimens are relied on to illustrate the type, since those produced in nature are frequently aberrant or deformed or deficient in foliage, owing to the struggle for ex- istence ; whereas plants grown in suitably poor soil, and free from crowding, give specimens such as may be found in nature under favourable circumstances. Address: — Rev. W. R. Linton, Shirley Vicarage, Derby. The Rev. Horace Waller, rector of Twymell, Northamptonshire, who died at that place on Feb. 22nd, is commemorated by Sir John Kirk in the genus Walleria. He was for some time unofficially connected with missionary work in Africa, and subsequently joined the Central African Mission under Bishop Mackenzie ; on his return to England he brought an interesting collection of the plants of that region. He took orders in the Established Church in 1867-8, becoming rector of Twymell in 1874.
