244 MR. E. G. BAKER ON THE 
Vegetation von Usambara und den angrenzenden Gebiete, there are 
13 species mentioned as occurring in that region, amongst them the very 
fine C. grandibracteata, Taubert, an ally of C. laburnifolia, Linn., but easily 
distinguished by the large bracts. Also noted as occurring there are 
C. Hildebrandti, Vatke, C. polychotoma, Taubert, and C. //olstii, Taubert 
but, as already stated, C. Hildebrandtit, Vatke, is C. axillaris, Dryander, and 
I think it is hardly advisable to separate C. polychotoma, Taubert, from 
C. mierocarpa, Hochst., or C. Holstii, Taubert, from C. Thomsoni, Oliver. 
In 1895, Dr. Taubert in Engler's ‘Pflanzenwelt Ost-Atrikas, Theil C, 
pp. 204-207, gives a useful list of the members of this genus occurring 
on the eastern side of the Continent. There are 56 species mentioned, of 
which 15 are novelties. These latter include C. imperialis, Taubert, and 
C. megistantha, Taubert, allies of C. agatiffora, Schweinfurth, this series 
having the largest flowers among the African species, with very longly 
stipiiate pods. Dr. Taubert uses the Groups adopted in the ‘Flora of 
Tropical Africa.’ 
In 1896, Part I. of Hiern's Catalogue of African Plants, collected 
by Welwitsch, appeared, in which the notes made by this excellent collector 
on his very fine Angolan collections are published. Also in the year 1896 
Dr. Schweinfurth published in the Bull. Herb. Boissier, Appendix, vol. ii., 
the determinations of the Leguminosze collected by him in Arabia and 
Eritrea. In the same year Dr. Taubert, in Engl. Jahrb. xxiii., described 
some new species. He there states that he considers C. florida, Welw., 
and C. globifera, E. Meyer, as synonymous, but I have compared types of 
both these plants and they appear quite distinct, both in inflorescence and 
character of pod. 
Dr. Schinz, in 1900, in * Die Pflanzenwelt Deutsch Siid-West Africas’ 
(Mém. de L’herb. Boiss. no. 1), gives a valuable enumeration of the plants 
of German South-West Africa, describing several novelties, but I hardly 
think it desirable to retain C. apiculata, Schinz, as specifically distinct 
from C. platysepala, Harvey, whilst C. Pechueliana, Schinz, is synonymous 
with C. argyrea, Welw. non Franchet, and the affinity of C. Belekii, Schinz, 
is rather with C. podocarpa, DC., than with C. natalitia, Meissner. 
In 1903 (in Bull. Herb. Boiss.) Dr. Schinz published 5 species from 
German South-West Africa. These were re-published in 1907 (Vierteljahr. 
Nat. Ges. Zürich) with certain additions. 
In 1908, in the Ann. del R. Inst. Bot. Roma, Dr. Pirotta published 
the * Flora della Colonia Eritrea, the Leguminose being by Dr. Chiovenda. 
It is interesting to find C. Deflersii, Schweinf., here recorded for Eritrea, 
but: I am doubtful about the plant recorded as C. cylindrica, A. Rich. 
This species is the same as C. tjrensis, Baker, but is not C. carinata, 
Steudel apud Schimper, no. 772, which is referred to it by Dr. Chiovenda. 
In 1909 Th. and Hélène Durand, in ‘Sylloge Flore Congolane,’
