Botany. — Annual Report, 1889. 



In the course of the past year the rooms containing the Herbarium and Library 

 were cleaned and painted, and the Herbarium cases M-ere re-polished. This work 

 occasioned a considerable interference with the proper work of the Department. 



During the year 51,652 specimens have been mounted, named, and inserted in their 

 places in the Herbarium. These have consisted chiefly of plants from Europe, col- 

 lected by various botanists ; from Portugal, by the Rev. R. P. Murray ; from Greece, by 

 Haussknecht ; from Singapore, by Ridley; from China, by Hance; from Japan, by 

 Bisset ; from Borneo, by Whitehead ; from the Atlas Mountains, by Johnstone ; from 

 Socotra, by Professor Balfour ; from Madagascar, by the Rev. Deans-Cowan, and 

 others ; from South Africa, by Professor MacOwan, Bolus, and others ; from 

 Australia, by Von Mueller, and others ; from Canada, by Professor Macoun ; from 

 Mexico, by Palmer and Pringle ; from Dominica, by Ramage ; and from the Republic 

 of Columbia, by Lehmann. 



In the progress of incorporating these additions, the following Natural Orders 

 have been more or less completely re-arranged : — CirryopliyUucea;, Hypericineoi, Gutti- 

 fercu, Ternstrceoniacccc, Coiiiposita', Cupullferca, IrUJacecv, Commelinacece, 

 Grwniinece and Filices. 



The Fungi have been entirely re-arranged, numerous Ahjo: have been incorporated 

 with the Herbarium, as well as extensive series of 3Iuscl and Lichenes. 



The exhibited series of British plants has been completed, as far as the vascular 

 plants are concerned, every species recognised by Bentham, in his British Flora, 

 being placed in the case, with its description from that work. 



A thorough revision and improved arrangement of the specimens and illustrations 

 exhibiting the Natural Orders of plants has been begun, and the whole of the Mono- 

 cotyledonous orders have already been completed. 



The extensive series of original drawings of Indian and Cliinese plants have been 

 mounted, named, and systematically arranged. 



The principal additions to the Herbarium during the year have been the acquisition 

 by purchase of the microscopic preparations made by the late Professor de Barj^ of 

 Strassburg, in connection with his investigations into plant anatomy and the para- 

 sitic diseases of plants. The total number of slides in this collection is 4,429, and 

 of these 1,220 are Fungi illustrating the life-histories of many plant diseases des- 

 cribed by de Bary, in numerous scientific papers ; 20G slides of Lichens, showing 

 especially the structure of the thallus ; 105 Characea? ; 40 Algse ; 11 Musci ; 280 

 Vascular Cryptogams; 1,160 Flowering plants; 1,112 slides illustrating de Bary's 

 researches on Plant Anatomy as described in his published works, and 289 slides 

 showing various points of plant structure. 



The Herbarium of Lichens, formed by Horatio Piggot, Esq., has been presented by 

 him to the Trustees. It contains many specimens collected by himself, and numerous 

 specimens communicated by Mudd, Leighton, and others, including the collection of 

 Dr. Deakin, consisting altogether of 2,383 specimens. It forms a valuable addition 

 to the collection of Lichens.
