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.
