the surrounding barren stems, and must be sought at the base of 

 the tufts, where they are somewhat obscured by their brown 

 covering leaves from which chlorophyll has disappeared. 



The known distribution of L. Schultzii is mainly subarctic ; 

 several records exist for North Germany, Denmark, Norway, and 

 Sweden ; it has been found near or within the Arctic Circle, at 

 Sarek in Lapland, Yenisei in Siberia, and the Yukon territory in 

 America. At Flordon in Norfolk, 52° 32' latitude, its first re- 

 corded station for the British Islands, it reaches one of its 

 most southerly points, being on practically the same parallel as 

 Neumark and Mohrin in Brandenburg. 



I am indebted to Prof. V. Schiffner and Herr Kaalaas for their 

 weighty assistance in determining this very interesting addition 

 to the British Flora, and to Rev. D. Lillie, Messrs. D. A. Jones, 

 S. M. Macvicar, W. E. Nicholson, and A. Wilson for their criticism 

 and the loan of specimens of this species and its allies. 



AFRICAN MILLETTIAS. 

 By S. T. Dunn, B.A., F.L.S. 



By the courtesy of the Director of the Royal Botanic Gardens, 

 Kew, the writer has recently been afforded the opportunity not 

 only of studying the rich collections of the genus Millettia pre- 

 served in the herbarium of that establishment, but of supple- 

 menting these with abundant material olitained on loan for him 

 from Berlin and Paris. His thanks are especially due to Dr. 

 Stapf, Dr. Harms, and M. Gagnepain for the friendly assistance 

 that they have given him regarding the collections in the herbaria 

 with which they are respectively connected. 



It will probably be a long time before so complete a mass of 

 African Millettia material can be brought together again, and as 

 full advantage as possible has been taken of the opportunity thus 

 offered for revising that perplexing genus. It has been particu- 

 larly fortunate that the types of Bentham's, Hooker's, and Baker's 

 species among the older African collections at Kew, and seldom 

 authentically represented in other herbaria, could be compared with 

 the more recent collections of French and German explorers. 

 Several doubtful points have been elucidated by reference to 

 Welwitsch's beautiful series of types in the Herbarium of the 

 British Museum (facilities for consulting which were kindly given 

 by the Keeper). 



It has been necessary to distinguish many new species, speci- 

 mens of which, bearing manuscript names, will be found in the 

 four herbaria mentioned. Pendmg the appearance of a more 

 elaborate description and arrangement of all the species, which is 

 now in preparation, it will therefore be convenient to indicate as 

 briefly as possible the relations of these new species with their 

 allies, and the following keys have been constructed with tliat 

 object :—
