Excerpt from Pittonia, Vol. 1 Our Pacific American plants differ from the Atlantic type of Echinocystis only in their more turgid seeds, hypogaeous cotyledons and perennial tuberous roots. In the seeds there is displayed every gradation between the Obovate and orbicu lar, and from nearly globose to much compressed. Eminent botanists who have given special attention to the Cucurbi faceae agree in the Opinion that the species in question form no more than a section of Echinocystis. In the natural orders most nearly allied, Cactaceae and Loasaceae for example, much more striking differences in the character of seeds are allowed in a genus. To take the case of M entzelia, the diversity of seeds, all the way from nearly shapeless to thin, orbicular, flat and winged on the one hand, and to almost exactly cubical on the other, is manifold greater than what we shall have in Echinocystis as allowed by Bentham and Hooker and Cog niaux. It is to be hoped that, in the small matter Of the priority of subgeneric or sectional names, no strifes may ever arise; but I can not conjecture What need there was seen to be Of naming this mara, as M. Cogniaux has done in his admirable mono graph, when Bentham and Hooker had, years before, applied megarrhiza to that use. The species, now in fair number, should be named as fol lows.
