[103] In his printed _Report on the Diseases of Wheat_, written for private circulation only, he has added in MS.--"In specimens of true mildew, the _three forms_--_Uredo rubigo_, _U. lincaris_ and _Puccinia graminis_, coexist simultaneously in the same sori, as well as numerous intermediate forms, which establish the specific identity of these fungi." _U. rubigo-vera_ is now regarded as a form of _Puccinia rubigo-vera_ and _Æcidium asperifolii_. [104] From the Professor's display of the methods he adopted of teaching Botany in schools, now in the South Kensington Museum, and Prof. D. Oliver's _Lessons_, etc. based on MS. left unfinished at my father's death, the floral schedule has been adopted in schools, not only all through the British Isles, but the Colonies as well.

JOHN LINDLEY 1799-1865 BY FREDERICK KEEBLE Rise of Systematic Botany--Lindley's place--early history--services to Horticulture--Professor at University College, London--_The Gardeners' Chronicle_--_Theory and Practice of Horticulture_--_The Vegetable Kingdom_--Orchids--his interest in Fossil Botany--personal characteristics. _Introduction._ The first half of the 19th century is a brilliant epoch in the history of botanical discovery. During that period the foundations of plant-anatomy were laid afresh with the cell as the builders' material. The discovery of sarcode or protoplasm electrified the scientific world and excited the attention of the philosophical novelist--as readers of _Middlemarch_ may remember. The nucleus, the only and true _deus ex machina_ of many a modern botanist, was recognised as an organ of the cell. Biochemistry came into being and, with Liebig as foster-parent, grew into modern Physiology. The natural system of classification proclaimed by Jussieu put to rout the old established Linnean system and the enunciation of the theory of Natural Selection brought the epoch to a dramatic close. In the constructive work of this period British botanists played a distinguished part, and it was due preeminently to them that the transition from the old artificial system to the new natural system took place so speedily and completely. The group of men to whose labours this great change was due include Hooker, Brown, Bentham and the subject of this sketch, John Lindley. Nor from this brief list may the name of Sir Joseph Banks, "the greatest Englishman of his time," be omitted. [Illustration: _Plate XIV_ JOHN LINDLEY (1848)]
