328 R. A. Dümmer. 
Caledon Div.: on slopes near Houw Hoek, 390 m, Oct. 1885. Bo- 
lus, 9869! 
The species can scarcely be intercalated in the S Involucratae, and 
possibly exhibits the most intimate affinities with A, Dregeana Sond. 
(S Diplopetalum), from which the very carinate leaves, their marginal and 
carinal ciliations, the smaller flower-heads, not ciliate calyx-segments, and 
strigillose ovary differentiate it immediately. The variety is characterised 
by larger growth, the cilia of the leaf-carina being deciduous, relatively 
longer pedicels, very minute bracteoles, the calyx-segments tipped by 
glands, shorter petals and petaloid staminodes, :

(1899). 
Coast Region. Clanwilliam Div.; Pakhuisberg, 750 m, 23, Aug. 
1896, Schlechter, 8609! (Herb. Kew and Brit. Mus.). 
Very like A. Dregeana Sond. in habit and superficial appearance, 
but distinguished according to the author by the dwarfer habit, shorter 
staminodes, very long clawed petals and hairy styles.

Allied to A. linifolia Lichst, but differing in the gibbous leaves, flo- 
wers, and bearded carpels.
