Riversdale, and others not further south than Komgha, while some, 

 again, i>ass from the South-western Region into the South-eastern 

 Region. They are comparatively few in the Karroo, and those species 

 which do occur there are species with a wide range of distribution, 

 e.g. volubilis, sylvatica, assimilis. Only one species, viz. assimilis, 

 occurs in the Kalahari proper, the others which are included under the 

 " Kalahari Region " in the geography, are found on the higher parts 

 of the Transvaal bordering the Drakensbergen. In the Houtbosch 

 and Barberton areas six species are known to occur, four of which 

 are also represented in the Eastern Region, such as Natal, East 

 Griqualand, Pondoland, Tembuland, and the Transkei, one species is 

 endemic (0. transvaalensis) , and one is widely distributed (viz. C. 

 assimilis). The latter species is the only one common to the typical 

 Kalahari Region and the above areas. These few facts while not of 

 much importance when considered by themselves, yet go to swell the 

 evidence that Barberton, Houtbosch, in fact the whole of the mountainous 

 part of Lydenburg and Zoutpansberg Districts in the Eastern Trans- 

 vaal should not be included in the Kalahari Region, but have a greater 

 affinity with the Eastern Region.

Flowers hermaphrodite. Calyx-tube adnate to the ovary, turbinate 

 or campanulate, very rarely almost obsolete, glabrous, rarely hairy ; 

 lobes ovate to linear, entire, sometimes toothed, rarely pectinate. 

 Corolla bi-labiate, tubular or segments free to the base, usually 

 glabrous, very rarely hairy ; corolla-tube rarely cylindric ; lobes linear 

 or lanceolate, acute or obtuse, sometimes acuminate. 'Stamens more 

 than, or less than, half as long as the corolla ; filaments either free to 

 the base or sometimes slightly monadelphous at the base, terete or 

 linear, usually widened below, usually hairy ; anthers cohering round 

 the style, usually pilose and bearded, sometimes glabrous. Ovary 

 half-inferior, 2-locular, many ovuled ; style passing gradually into the 

 ovary, rarely almost obsolete ; stigma capitate, terminal or oblique. 

 Fruit partly enclosed by the persistent calyx-tube, many seeded. 



Herbaceous perennials, often with tuberous roots. Stems erect or 

 twining, leaves cauline or more rarely wholly radical, alternate, entire 

 or divided, with margins serrated, toothed, crenate or entire, varying 

 from linear to broadly ovate. Inflorescence lax, rarely very dense, 

 either a distinct raceme at the end of the stem or the flowers arranged 

 in a racemose manner in the axils of the upper leaves, rarely the 

 inflorescence in 2-4-flowered umbels in the axils of the leaves. Bracts
