in the year 1860, although in the preface to the ‘ Flora Capensis’ the thanks of the 
authors are said to be due to Burchell for the verification of several of the species of 
Polygala first described from his specimens. 
Burchell, no. 2474: in a walk to the Great Klibbolikhónni Spring (or source of the 
river Kráüman), November 25, 1812. 
Burchell, no. 2599: at the Kosi Fountain, on the morning of December 25, 1812. 
It was at this station that Burchell at the same time obtained specimens of our Fimbri- 
stylis Burchellii, described below, page 28. The species belongs to the group eontaining 
the East-Indian Р. rosmarinifolia, Wight et Arn.

Our specimen consists only of a flowering stem or branch; it bears some resemblance 
to Dianthus prostratus, Jacq. ; but it differs from it by the more acute form of the general 
outline of the blade of the petals, and by the more deeply cut margins of the same. 
The principal figure in Plate III. A. represents the natural size of the specimen; the 
dissected flower is enlarged to about two diameters.

Harv. in Harv. et Sond. Fl. Cap. i. p. 228 (1860); non Hochst. (1847). 
Our specimens possess flowers and fruits, and quite agree with Sonder’s species, which 
has also been obtained from the Transvaal and Zululand. Ina flower opened for exami- 
nation the stamens were 18 in number. Hochstetter’s T. trichocarpa, from Abyssinia, 
is quite distinct. -
