and I have to thank the Directors of those establishments, and also Dr. Urban 
and Dr. Harms, for their kindness and courtesy, and especially to thank 
Dr. Schinz for the kind loan of his unrivalled collections from German 
South-West Africa. When at Berlin I also had the opportunity of consulting 
Dr. Schweinfurth’s very fine collections from Bongoland and Niamniamland ; 
and at Paris, thanks to the courtesy of Dr. Lecomte, I have been enabled to 
study the types of Lamarck’s Herbarium. 
I have also to thank my friends Mr. Spencer Moore, Mr. N. E. Brown, 
and Mr. T. A. Sprague for kind help, and I am indebted to Miss R. M. 
Cardew for the drawings. 
SUMMARY OF RESULTS. 
In this paper I have given short descriptions of the 309 species known to 
me as occurring in Africa. Of. these, 40 belong to the Sect. Simplicifolie, 
66 to the Sphærocarpæ, 7 to the Chrysocalycinew, 4 to the Spinosee, 5 to the 
Faretze, 25 to Kucrotalaria subsect. Grandifloree, 62 to subsect. Mediocri- 
Hore, 49 to subsect. Parviflorze, 33 to subsect. Oliganthe, 18 to subsect. 
Stipulosee. 
The genus extends from Egypt and the Sudan and the Sahara in the 
north, to Cape Colony in the south. The species occurring in Egypt are 
C. egyptiaca, Benth., and C. thebaica, DC., two shrubby plants belonging to 
the Simplieifolize, with a subephedroid habit, not allied to any other African 
species except C. arenaria, Benth. 
C. Sahare, Cosson, trom the Sahara, is also a species without any distinct 
alliance to any other African member of the genus. 
There are 76 novelties described, but some of these are species which I 
found at Berlin, with MS, names by Dr. Taubert or Dr. Harms. Of these 
novelties, 9 belong to the Sect. Simplicifolize, 21 to the Sphærocarpæ, 1 to 
the Spinosee, 45 to Eucrotalaria. 
PROPERTIES OF THE GENUS. 
Several species of this genus have a most injurious effect on stock. 
This has been discussed by Mr. J. Burtt Davy * in his paper “ Notes on 
Crotalaria Burkeana and other Leguminose causing Disease in Stock,” 
and in a paper “ Eine neue, für das Vieh gefährliche Crotalaria-Art aus 
Deutsch Ost-Africa (C. Zimmermannit), von E. G. Baker, mit einem Zusatz 
über giftige Crotalarien Ost-Africas, von Dr. Harms”, The interesting 
point to notice is that the species possessing injurious properties are all 
nearly allied to one another. The species are C. Zimmermannii, Bak. fil., 
C. polysperma, Kotschy, C. Burkeana, Benth., and perhaps C. Quartiniana,
