In my first paper (1951) a part of the tribe Eupodostemeae was revised, viz. the genera Apinagia, Marathrum, Rhyncholacis, Lophogyne, Monostylis, Jenmaniella, Wettsteiniola and Macarenia. The second part deals with the subfamily Tristichoideae, which comprises the genera Tristicha and Weddellina, and the tribe Mourereae of the subfamily Podostemoideae, which consists of the genera Mourera, Lonchostephus, and Tulasneantha.
