﻿Harpagophytum.] pedaline^ (Stapf). 459 



I suspect this to be an extreme form of H. procumben.iy charactorizcd by small, 

 slightly lobed or dentate leaves, smaller flowers and the copious development of 

 small, rigid hairs of the same nature as those found in the young parts of H. 

 procivmbens. The colour of the corolla is evidently yellow "in the lower, and 

 more or less purple in the upper part. 



IV. EOGEBIA, J. Gay. 



Calyx small, 5-parfcite. Corolla: tube funnel-shaped to almost 

 cylindric, slightly gibbous to saccate on the posticous side of the 

 hase ; limb spreading, obscurely 2-labiate ; lobes suborbicular, sub- 

 equal. Stamens i, didynamous, inserted low down in the corolla- 

 tube ; filaments long, filiform ; anthers parallel, ovate-oblong, dorsi- 

 fixed. Ovary unequally 2-celled ; posticous cell much shorter and 

 smaller; anticous cell divided imperfectly (in the lower part), 

 posticous cell divided perfectly by a spurious septum ; ovules 

 numerous and about 4-seriate in each of the anticous, few and 

 1-seriate in the posticous divisions. Capsule obliquely ovoid, 

 rostrate, armed with 2-8 conic spines or tubercles, the large anterior 

 cell tardily loculicidal to the middle, the posticous indehiscent. 

 Seeds oblong, angular ; testa reticulate. 



Erect, annual, succulent herbs ; leaves broad, long-petioled ; flowers in axillary 

 few- to 1-flowered cymes on short pedicels, violet or white.
