]ia, by Baron von Mueller; of specimens of Gompositce, 

 Apocynacece, Asclepiadacece, Boraginece, and LahiatcB from 

 various regions, and by different collectors ; and of numerous 

 specimens of various orders from the Herbaria of Triana, 

 Miers, Wilson, Auerswald, Ravenel, Moore, and Shuttle- 

 worth. 



In the progress of incorporating these additions the fol- 

 lowing Natural Orders have been more or less completely 

 revised : — Malvacece, Celastrinece, MelastomacecB, Gompositce, 

 Apocynacece, Asclepiadaceoi, Boraginecb, Lahiatce, Orchidece, 

 Iridaceoi, Xyridacece, and Grawiineoi. 



In the progress of the work the officers of the Department 

 have been engaged as follows : — 



Mr. E. G. Baker has incorporated the Polypetalce of various 

 collections with the general Herbarium. The principal of 

 these have been the plants from Mexico, by Palmer, Pringle, 

 and Ghiesbrecht ; from Uruguay, by Aplin ; from Australia, 

 by von Mueller ; from India, by Gamble, Clarke, and King ; 

 from Lifu, by Whitmee ; from the Transvaal, by Rehmann ; 

 from the Cape of Good Hope, by MacOwan and Bolus, and 

 from Sierra Leone, by Scott Elliot. 



He has completely revised the Order Melastomacece, and 

 arranged it in accordance with the recent Monograph of Prof, 

 Cogniaux. The genera Mcdachra, Urena, and Gossypium 

 have also been critically named and arranged after recent 

 raithors, the latter genus with the assistance of Dr. Watt, of 

 Calcutta. He has completed his enumeration of the Mal- 

 vacece, which has been carried on for several years. 



Mr. James Britten has incorporated with the Herbarium 

 a large number of plants belonging to the Orders Gom- 

 positce, Apocynacece, Asclepiadacece, Boraginece, and Lctbiata'. 

 He has named the African species of these and other Monope- 

 talous Orders, and nearly completed the naming and 

 arranging the very large collections of American Gompositce. 

 Several collections of African plants have been incorporated 

 with the Herbarium, including those of Welwitsch, Scott 

 Elliot, Buchanan, Wood, arid Bolus ; and the new species of 

 Mr. Whyte's collections from Milanji have been described. 

 He has also superintended the temporary arrangement of the 

 Monopetalce not yet incorporated with the Herbarium, and 

 has named a considerable number of small groups of plants 

 in accordance with recent monographs. Mr. Britten has 

 devoted some time to the arrangement of the collection of 

 prints and drawings of plants, and has superintended the pre- 

 paration of the Library Catalogue. 



Mr. A. B. Eendle has incorporated the Monocotyledoms 

 and Gymnosperms of the following collections : From Europe 

 by Schulz ; from Paphlagonia by Sintenis ; from Syria by
