glabrescent except for the sunken midrib and its three to ten pairs of 

 lateral nerves, persistently white-felted below, the midrib and nerves 

 correspondingly raised ; margin entire or distantly denticulate, closely 

 and shortly ciliate. Scapes solitary or in pairs, short and stout, or 

 long and slender, 2-12 inches long, scaleless, covered with a brownish 

 deciduous cobwebby tomentum. Involucral bracts 2-seriate, narrow 

 acuminate, white tomentellous below, dark brownish tomentellous 

 at the tips, rarely exceeding J-| inch in length. Flower-head small, 

 inch in diameter, the ray-florets sulphur-yellow, narrow, and 

 sHghtly exceeding the longest involucral bracts. Pappus snow-white,

G. cordata, a more eastern species than the preceding, extending 

 from the Knysna districts eastwards along the coast to Kaffraria, has 

 Httle to recommend it from a horticultural standpoint, as the ray- 

 florets are yellow and far too short, scarcely exceeding the involucral 

 scales at times. In clearings of the Knysna forest it is, in conjunction 

 with its congener G. ferruginea and the Bracken, one of the first 

 plants to clothe the ground. 



Burchell states that the ray-florets are white, and this is very hkely, 

 for many of the Gerberas appear to be extraordinarily variable in colour.
