 RAFFLESIA AUXOT.DT. 11.")

acotyledonous embryo, exists equally in Orchidece. And if it be ein])loye(1 aloiipj with those charaeters connected with their pecuHar econoiny, namely, the imperfect development of leaves, the want of stomata and absence of green colom*, the class cannot be limited to Jlafllcnacc^e and Bahnwplio- rece, for an embryo of exactly the same kind exists in (Jru- hanche, and other, perhaps all other, genera parasitic on roots, a remark which I made, thongh not with snlHcient precision, in my former essay. ^ Jhit snch a classification, though founded on seemingly very important technical cha- racters, Avould hardly be received in a strictly natural ar- rangement, and it seems to me fpiite as paradoxical to ap- proximate two such genera as RaJ/lcsia and B(d(iiioj)hora.
