Notes
Lindau, in Engl. Jahrb. xvii. Beibl. 41, 37, places correctly T. angulata, Hook. (a Madagascar plant), in the section which has the anther-cells spurred at the base. The original picture of Hooker (Exot. Fl. t. 166) shows the Madagascar plant correctly, the separate enlarged anther incorrectly, but Hooker says his picture was taken partly from Cape material. T. Anderson, who united the two species, does not appear to have looked at the anthers.
