Marsdenia

After the first volume of this revision had gone to press, it was pointed out to us by Mr A. A. Bullock that the species described below should be segregated from Marsdenia as a distinct genus – Cionura Griseb. – in which its correct name is C. erecta (L.) Griseb. Mr Bullock remarks that the species is more closely related to Dregea than to Marsdenia, from which it differs by the cymes being lateral at the leafy nodes (not in narrow elongated thyrsiform panicles) with much larger flowers which have a very short tube and more or less sinuate spreading lobes (against small flowers which are more or less urceolate-campanulate, with the tube much longer than the lobes).
