Glaberrima, circiter 1 met. alta. Caulis teres, sulcatus, foliatus, divari- 
cato-ramosus, ramis erecto-patentibus 5-15 cm. longis. Folia radicalia, 
30 cm. longa, 3-5 cm. lata, auguste oblonga, apice rotundata, basin versus 
in petiolam brevem attenuata, grosse dentata, dentibus bifidis vel trifidis 
acuminatis ; caulina amplexicaulia, remota. Involucri segmenta 10, sub- 
sequalia, acuta, valde carinata nervataque, coriacea. Calycis dentes, 
•7 mm. longae. Eructus ad apicem leviter muricatus. 
An erect, entirely glabrous plant, 3^ ft. high, with a terete grooved 
divaricately branched leafy stem ; branches ascending and spreading, 
2-6 in. long. Eadical leaves narrowly oblong, 13 in. long, 1^-2 in. broad,

South Africa. Bedford Div. : On the summit of the Kaga Berg,

Scott-Eliott, 432 ! 
This species w^as included in the set of Alepidea amatymbica, 2189, 
distributed by Ecklon and Zeyher, but is obviously distinct, the bifid or 
trifid marginal teeth of the leaves, the involucres of ten subequal 
segments and the larger calyx-teeth being the most salient points of 
distinction. It commemorates the name of the late Professor P. 
MacOwan, the distinguished Cape botanist.
