part of these plants, has revised previous work, has elaborated 

 Orders hitherto untouched, and described a large number of 

 new species. Except for a few genera of grasses, the Monocoty- 

 ledons are now ready for publication. This has necessitated 

 considerable revision of the material from Tropical and South 

 Africa and elsewhere contained in the Herbarium. The Mono- 

 cotyledons, Gymnosperms, and Apetalous Dicotyledons of 

 various collections have been selected and laid out for incor- 

 poration ; and Dr. Eand's collection from Rhodesia and Mr^ 

 Andrews' from Christmas Island have been worked out in 

 part. A considerable number of cultivated Orchids and other 

 plants have been obtained by correspondence and prepared 

 for incorporation ; several new species have been described. 

 In conjunction with Mr. Schlechter (of Berlin) the genus 

 Lachenalia has been revised. 



Commencing work in April, Mr. Moore has been employed 

 in incorporating into the Herbarium a large number of Com- 

 positse. European and North Asiatic species were first dealt 

 with, and with them were taken the Compositse of the Auers- 

 wald Herbarium. North African and Oriental collections 

 followed; and then those composed of Indian and Central 

 Asiatic specimens. Work is now proceeding on the Malayan 

 and East Asiatic collections, to be followed by those con- 

 taining Australian, African, and American species. A con- 

 siderable number of species and two or three genera new 

 to the Herbarium have, by these means, been made avail- 

 able for examination, and Mr. Moore has taken advantage 

 of the opportunity offered by the laying in of these plants to 

 name a number of specimens which, in the absence of authentic 

 material, could not be satisfactorily determined before. 

 Among gene '-a which have been largely added to may be 

 cited Anthemis, Achillea, Serratula, Girsium, Centaur ea, 

 Scorzonera, and Hieraciumi. The last-named has been re- 

 arranged in accordance with Fries's " Epicrisis Generis 

 Hieraciorum " and Nyman's " Conspectus Florae Europese," 



Mr. Hiern, in addition to his work at the Welwitsch Cata- 

 logue, has incorporated African plants belonging to many 

 natural orders of Dicotyledons. 



Mr. Gepp has been occupied chiefly with the preparation 

 of the account of the Mosses in the Catalogue of Welwitsch's 

 African Plants, in connection with which he has found it 

 necessary to make a careful re-examination of the Mosses of 

 Welwitsch's Herbarium, and a wide comparison of them with 

 the moss-floras (so far as they have been ascertained) of the 

 various territories of West Africa, and to revise several 

 genera included in the natural orders, Bartramiaceai, 

 Bryaceai, Fissidentacew, Hypoyterygiaceoi, CTy2')liaiaceai, 

 Neckeraceoi, Hookeriacece, Fabroniacece, Leskeacece, Hyj)- 

 nacece. The number of Mosses, Hepatics, and Lichens, 

 selected from the Herbaria of Shuttleworth, Wilson, and 

 Stephani, and from numerous smaller collections^ that have
