18.— The Genus Calpurnia, E. Mey. (Leguminosae) .—By E. P. 

 Phillips, M.A., D.Sc. F.L.S., Assistant. 



CALPURNIA E. Mey. 



Calyx campanulate, 5-dentate, the two upper lobes smaller and 

 partly connate. Vexillum clawed; claw deeply channelled; limb 

 bilobed at the apex and reflexed ; alae clawed, oblong, obtuse ; carina 

 clawed, usually plano-convex in outline, obtuse. Stamens 10; fila- 

 ments 'free or connate at the base, glabrous, or rarely pubescent ; 

 anthers small, oblong. Ovary stalked, glabrous, villous, or ciliate- 

 on the sutures, several ovuled ; style arcuate; stigma small, capitate. 

 Legume stalked, usually broadly linear, sometimes with a narrow 

 wing on the ventral suture, tipped with the remains of the style. 



Shrubs or small trees with yellow flowers, and glabrous or pubescent 

 or more rarelv villous branches. Leaves pinnately compound with 

 3-many pairs' of leaflets ; leaflets usually pubescent, more rarely 

 softly tomentose, obtuse or refuse at the apex, frequently mucronate. 

 Inflorescence racemose, axillary or terminal, frequently arranged in a 

 paniculate manner, few to many-flowered, longer or shorter than the 



leaves. 



A small genus of 7 known species which are mainly found m the 

 eastern parts of South Africa. Three of the species have a wide- 

 range of distribution, while the remaining 4 are all local. C. sylvatica, 

 for "instance, extends from Somerset East to Colenso in Natal; 

 C. intrusa from Komgha, through Pondoland, East Griqualand, and 

 Natal into Basutoland, and as far north as Harrismith in the Orange 

 Free State ; G. lasiogyne has not been recorded further south than 

 Natal, but is again found at Barbeton in the Transvaal and extends 

 into Tropical Africa. C. floribunda has only been recorded from the 

 Albany Division, C. robinioides from Basutoland, and C. Woodn from 

 Natal. An incomplete specimen which appears to be a species of 

 Calpurnia has been collected by Dr. J. Muir in the Riversdale Divi- 

 sion, in which case the area of distribution would be extended west- 

 wards along the southern coastal belt. 



I am much indebted to Mr. N. E. Brown, A.L.S., who kindly sent 

 me a list of the material in the Kew Herbarium.
