For quite a considerable time this common and well-known _Dimorphotheca_
was placed in herbaria under the name of _Dimorphotheca Ecklonis_, and
Harvey, who examined specimens of this plant collected by Burke and
Zeyher on the Aapies River and Magaliesberg, also included it under _D.
Ecklonis_. Dr. Schlechter first recognised that the Transvaal plant was
an undescribed species, but apparently did not realise that Burke and
Zeyher had collected the plant close on a hundred years ago, as he
founded his description on specimens collected by Mr. E. E. Galpin,
F.L.S., in 1887, on the Saddleback Mountains, Barberton.
_Dimorphotheca spectabilis_ is a spring flowering plant, and is common
around Pretoria during the months of September and October. It is a
well-grown plant with large mauve flowers, and if introduced into
cultivation would be an acquisition to any garden. The plant sets seed
freely, and could easily be raised by this means. The species is
poisonous, and in experiments carried out by the Division of Veterinary
Research, the plant was found to cause death in sheep fed on it.
Specimens are preserved in the National Herbarium, Pretoria (Herb. No.
1470).
