Department of Botany. 



I. — Arranffement and Conservation. 



During the past year 13,475 specimens have been incorporated 

 with the Herbarium. This number includes 12,825 Flowering 

 Plants, 270 Mosses, 80 Hepatics, 134 Lichens, 4 Algae, and 162 

 Fungi. 



The restoration to the Herbarium and Library o£ types and 

 other specimens and volumes of unique interest which had been 

 removed from the Department for greater security during the War, 

 has occupied part of the time of the Staff ; the type-specimens have 

 been indicated by a special label, and the opportunity was taken for 

 some work of revision and rearrangement. The large series of 

 specimens from the Hortus Cliffortianus have been correlated with 

 the published volume by Linnaeus of the same title, and re-arranged. 



Flower'mci Plants. — Collections acquired during the year have 

 been mounted and incorporated wholly or in part ; and also out- 

 standing specimens of various collections from Australia, and 

 generally, in various families, especially (Jommelinaceae, Aracese, 

 Cyperacese, Graminese, Anonacese, Myrsinaceae, Urticacese, and 

 Cupuliferse. Work of revision and re-arrangement has been done 

 in various families and genera. The European Herbarium of the 

 late R. P. Murray has been partly incorporated. The collection of 

 hand-specimens of woods used in commerce has been re-arranged, 

 and progress has been made in making and fitting trays in the 

 cabinets of the general collection of woods, for the better arrange- 

 ment of the specimens for consultation. 



Cryptogams. — Work preliminary to incorporation has been done 

 in the various groups, progress has been made with the sorting and 

 selection of the Stirton collection of Lichens, and with the 

 determination and classification of unnamed British Lichens. 



Exhihition Series. — The several series in the Public Grallery have 

 been maintained, and additions have been made in various families. 

 The family Cornacese has been re-arranged. British and cultivated 

 specimens have been collected and prepared for exhibition. 



Catalogues and Guides. — The preparation of Volume IV of the 

 Flora of Jamaica by Mr. Fawcett and Dr. Rendle has been 

 completed and in great part printed, a new edition of the Guide 

 to the Mycetozoa has been prepared and published, and progress has 

 been made with the preparation of a new edition of the List of 

 British Seed Plants and Ferns.
