RAFFLESIA ARNOLDI. 415 



acotyledonous embryo, exists equally in Orcliidece. And if 

 it be employed along with those characters connected with 

 their pectdiar economy, namely, the imperfect development 

 of leaves, the want of stomata and absence of green colour, 

 the class cannot be hmited to Baffiesiacece and Balanopho- 

 rece, for an embryo of exactly the same kind exists in Oro- 

 banche, and other, perhaps all other, genera parasitic on 

 roots, a remark which I made, though not with sufficient 

 precision, in my former essay. ■^ But such a classification, 

 though founded on seemingly very important technical cha- 

 racters, would hardly be received in a strictly natural ar- 

 rangement, and it seems to me quite as paradoxical to ap- 

 proximate two such genera as Babesia and Balanophora.
