Mr. Gepp has been employed in preparing for publication 

 the Mosses for the Catalogue of Welwitsch's African Plants, 

 and in pursuance of this work he has found it necessary to 

 make a wide revision of other Mrican collections, for 

 example, Dusen's Musci Africani in Camerunia collecti, 

 Breutel's Musci Capenses, and Eehmann's Musci Austro- 

 Africani. He has re-cast and le-written the account of 

 Welwitsch's Hepatics ; has determined the names of the 

 Vascular Cryptogams and MuscinesB gathered in Christmas 

 Island by Mr. Andrews, and has supplied assistance in the 

 preparation of a Botanic Glossary for publication. He has 

 laid out and incorporated in the general collection a further 

 portion of Stephani's Hepatics, and has revised several genera 

 of the Hypnacese, Leskeacese, Neckeracese, Hookeriacese, &c. 



Mr. Blackman's work has been chiefly of two kinds, that in 

 connection with the conservation of the collections of Fungi 

 and Lichens, and that in connection with the Public 

 Gallery. In the former, among other work may be men- 

 tioned the working out with Miss Smith of the collection of 

 Fungi and Lichens made by Mr. Andrews in Christmas Island. 

 In the Public Gallery cases have been arranged, with the 

 assistance of Mr. Horrel], to exhibit in a manner that is of 

 interest both to students and to the general public, some of the 

 more striking and important adaptations to be met with in 

 plants. The first case deals chiefly with the peculiar modifi- 

 cations of form and structure exhibited by xerophytic or 

 dry-country plants. In a second case, which is nearly 

 completed, the peculiar characters of water plants, salt-marsh 

 plants, alpine and arctic plants have been displayed in a 

 similar manner. Also with his co-operation Mr. Horrell has 

 begun an exhibition case dealing with the Vascular 

 Cryptogams, both recent and fossil, from a systematic point 

 of view. 



The most notable addition to the collection by presentation 

 during the year was the moss herbarium of the late Charles 

 Lyell, Esq., of Kinnordy, containing 1,120 specimens pre- 

 sented by Sir Leonard Lyell, Bart. 



Of the additions by purchase, the collection of 7,703 slides 

 of Marine Algae, mostly Floridese made by the late Prof. 

 Schmitz, of Greifswald, and the herbarium of .3,121 British 

 Mosses of the Rev. H. G. Jameson were the most important. 



The additions to the collections by presentation have 

 consisted of : — 8 Plants from Australia and New Guinea, 

 from F. Manson Bailey, Esq. ; specimens of a Senecio 

 from Prof. Perceval Wright .; 327 Plants from Tropical Africa, 

 from Lord Delamere ; 1,239 Plants from South Africa, from 

 Major Wolley Dod ; 7 Orchids from Sir Trevor Lawrence, 

 Bart ; specimens of Schimmelia from E. M. Holmes, Esq. ; 

 188 Plants from Arabia, Pro v. Oman, from Surg. Lieut.-Col. 

 Dr. A. S. G. Jayakar ; 15 Plants from California and Oregon, 

 from H. E. Brown, Esq. ; 71 Phanerogam^ and Cryptogam^
