A. Richard published his account of the Flora of Abyssinia in 1847, 
describing the 21 species occurring in that country ; and in 1861-62 Harvey, 
in the ‘Flora Capensis, gives descriptions of 24 then known to occur 
in South Africa. Of these species, C. spartioides, DC., C. lanceolata, 
E. Meyer, C. Burkeana, Benth., C. striata, DC., C. globifera, E. Meyer, 
C. platysepala, Harvey, C. capensis, Jacq., and C. natalitia, Meissner, are 
now known to occur also north of the Equator. The number of species, 
therefore, restricted to South Africa is much smaller than in the genus 
Indigofera, where we have a large number endemic south of the Equator. 
In 1862 Klotzsch described the collections of Peters in Peters’s 
Mozambique Flora; and in 1871, in Prof. Oliver’s ‘Flora of Tropical 
Africa, my father (J. G. Baker) described the 106 species then known to 
occur within the limits of the area of the Flora, Here for the first time the 
very rich collections made by Welwitsch, in Angola, are described. It 
may be interesting to note the distribution of these 106 species in the 
main geographical divisions adopted in the Flora; 33 of these occur in 
^ 
Upper Guinea, 39 in Nile Land, 52 in Lower Guinea, 19 in Mozambique 
District, and 4 in South Central Africa. Most of the species fromg Lower 
Guinea are from Angola ; it therefore appears that Angola is richer in 
species than any other portion of Africa. 
With comparatively trifling alterations I retain most of the species there 
described, the principal exceptions being that C. cylindrica, A. Rich., has 
as the older name to take the plaee of C. tigrensis, Baker; C. Onobrychis, 
A. Rich., is perhaps only a subspecies of C. astragalina, Hochst. ; C. elata, 
Welw., appears to me to be hardly specifically distinct from C. lachno- 
carpa, Hochst. ; and C. ramosissima, Baker, must become C. huillensis, 
Taubert, as there is an earlier C. ramosissima, Roxb. 
Shortly after the publication of .the ‘Flora of Tropical Africa,’ Franchet 
described the plants collected in Somaliland by M. Revoil, among them 
many Crotalarias. Unfortunately he called one of his species C. argyrea, 
a name previously used by Welwitsch for a different plant. He also 
published C. dumosa, which is synonymous with C. Jamesii, Oliver ; and 
C. petiolaris, an ally of C. laburnifolia, Linn., of which a southern variety 
occurs in the Transvaal. 
In 1878 and 1879 Vatke published the plants collected by Hildebrandt in 
the ° Uisterreiche Botanische Zeitung,’ enumerating 24 species, 4 being 
novelties ; and in 1892 Drs. Engler and Taubert described the Crotalarias 
in the ‘ Hochgebirgs Flora des Tropischen Afrika,’ but one of the species 
described by Taubert, C. kilimandscharica, is synonymous with the earlier 
C. natalitia, Meissner. In 1894, in Engler’s ‘Ueber die Gliederung der
