Pr ciin— The Mercurialineae and 
the same Dregean specimen. The plant which forms the original M. caffra , later 
M \ caffra , a brevipes, is the same as that portion of Adenocline pauciflora , Turcz., 
which has opposite leaves. The two plants can be fairly easily sorted out in herbaria 
because a brevipes usually dries to a straw-yellow or yellowish-green colour, whereas 
longipeSy the original Adenocline Mercurialise Turcz., dries green. But there is no 
other tangible differential character, for both forms vary in size of leaf, length of 
petiole, character of leaf-base, and toothing of the leaf-margin. As the only certain 
character is one that can hardly be expected to prove of value in the field no good 
purpose is served by the continued recognition of Meissner’s two varieties.
