Abstract
THE Royal Horticultural Society's Lily Year-Book for 1936 (London, from the Society's Office, Vincent Square, Westminster, S.W.I., 5s. paper, 6s. cloth, 1936) includes a number of contributions to a scientific understanding of lily culture. Dr. Fred Stoker has made a study of the contractile roots of these plants. He shows that members of the Eulirion section of the genus Lilium possess such structures. Much interesting information as to how contractile roots of daughter bulbils penetrate the root-plate of the mother bulb, is imparted, and the microscopic anatomy has been investigated. An attractive feature of the volume is a bibliography of more than 550 references to published works upon lilies. This has been compiled by the Abbe Souillet, and although it appears comprehensive, it does not claim to have included a large number of articles which have appeared in English periodicals from time to time. A paper by Dr. M. A. H. Tincker shows that a suitable soil temperature of 65°–70° F. is an important factor in the propagation f lilies from bulb scales. It is interesting to note that soil heating by electric cables or hot-water pipes is suggested as an aid to this method of propagation. Many other papers communicate knowledge upon geographical or horticultural aspects of lily growing, and an interesting note by Mr. P. Rosenheim announces the discovery of an early treatise on the lily, contained in a German encyclopaedia by Kruenitz and Floerke, dated 1800.
