 King, of Plaistow, whose photograph of the plant is reproduced at 

 Fig. 215, I have compared M^. King's riant v/ith leaves from the 

 typ" of T. luderitzii kindl^^ communicated by ^r. A. Tischer, and 

 find thpt the latter are identical with those of ^'-r. King's plant. 

 Dr. Tischer has not seen its flowers, but the much longer pedicels 

 as well as the leaf char^ cte"s seem clearly to distinguish this 

 plant from "7. Schwantesii.
