The plant here figured, after a careful examination by 
Mr. N. E. Brown, is referred by him, I think correctly, 
to the species above-named; though in the absence of 
fruit, which has not matured in this country, the absolute 
determination is not arrived at. De Candolle places it in 
the section Osteospermopsis, characterized by the sterile 
disk-flowers, the achenes of the ray-flowers being ovate- 
oblong, trigonous, smooth or subtubercled at the top. 
All the species of this section he regards as doubtful 
Dimorphothece, and perhaps more allied to Osteospermum. 
Six species of Dimorphotheca have been figured in the 
earlier volumes of this work, namely D. aurantiaca, DC. 
(Calendula Tragus, +. 408); D. Tragus, DC. (C. Tragus, t. 
1981) ; D. cuneata, DC. {Arctotis glutinosa, Sims, t. 1343) ; 
D. chrysanthemifolia, DC. (Calendula, t. 2218) ; D. gramini- 
folia, DC. (nudicaulis, DC. t. 5252); and D. Barberix, Harv. 
t. 53837. From all these D. Ecklonis differs in its shrubby 
stem and branches, in this respect coming nearest to D. 
: _ DC., the stem of which is woody, but at the base 
only. 
The only authentic specimen of D. Ecklonis in the Kew 
May Ist, 1897.
