This is the Aptosimum mentioned by Burchell, Trav. S. Afr. i. 341. The 

 amount and extent of the hairs on the margins of the leaves and petioles are very 

 variable; in Burchell's type specimens (1217) the leaves are in some cases 

 very nearly glabrous, while in others they are ciliate below the middle, and the 

 petioles are nearly glabrous or ciliate ; in his original description he characterized 

 the leaves as pubescent or often naked. The specimens (1252) gathered by 

 him two days later ift-the same division, and considered by him to be the same 

 species (see Burchell, i.e. i. 225) have their leaves and petioles strongly ciliate, 

 just as in Engler's A. nanum. The calyx-lobes iu the only flower examined of 

 A. nanum are slightly shorter than in Burchell's type of A. indivisum. 



10. A. depressum (Burchell, Trav. S. Afr. i. 260, without de- 

 scription) ; a low undershrub, prostrate, densely or numerously 

 branched, rigid ; branches more or less woody at least below, short or 

 in some states elongated, leafy throughout, woolly pubescent or 

 glabrous ; leaves obovate, often narrowly so, occasionally subrotund, 

 mucronulate or acuminate, not spinous at the apex, narrowed to the 

 petiolate base, entire, pubescent or glabrous, \-^ in. long, l^V"? i"- 

 broad, sometimes secund ; petioles usually about as long as the 

 leaves ; flowers axillary, numerous, sessile, inserted on the upper side 

 of the branches, mostly exceeding the leaves, i-| in. long, fragrant; 

 calyx subglabrous or woolly outside, woolly or pubescent within ; 

 lobes lanceolate ; corolla puberulous, blue or purple ; tube very 

 slender at the base ; throat broad and long ; capsule emarginate, 

 nearly as long as the calyx; seeds attached by the membranously 

 dilated entire or lacerated funicle. Lindl. Bot. Reg. t. 1882 ; Benth. 

 in DC. Prodr. x. 345, Euellia depressa, Linn.f. Suppl. 290 ; Tliunh.

The following forms, though very different in extreme cases, are closely 

 connected and cannot be distinguished by good characters : — 



;8, Benthami ; branches and leaves dense and glabrous. 



7, elongatum; branches considerably elongated, comparatively slender.
