VERBENACE (Pearson). 181 
It is stated in Harvey’s “Genera of South African Plants” (2nd edition) 
that the genus Stachytarpheta is represented by “1 or 2 Cape species, probably 
naturalized ” (1. c. 290). No specimens, however, are preserved in the Kew, 
British Museum, or Harvey’s Herbarium, and I have failed to find any authority 
for the statement. 
A cultivated specimen of Holmskioldia sanguinea, Retz., from Griqualand 
East is in the Kew Herbarium.
