the ovuhi, ill the stnicturo of the seed and in that of the 

 aiithene. 



The second section, Ilj/clnorrcc, formed of Uf/clnom alone, 

 is characterised by its completely adherent ovarium, singu- 

 larly divided stigmata, the peculiar oriuin and struct ure of 

 its pendulous phicentfe, its embryo enclosed and seated in 

 the centre of a dense albumen, and by the arrangement 

 and structure of its anthera\ 



In the third section, or ("y///^^^, the placenta) are piirietal, 

 the ovarium is connate with the calyx, Jind the cellular [-230 

 undivided embryo forms the whole mass of the seed, or is 

 apparently destitute of albumen.^ 



That this third section is nearly related io Asarince seems 

 to me unquestionable ; if, therefore, its aitinity to lli/dnora 

 and liaj/lcsia be admitted, the place of this singular family 

 would be nearly established. 



That Bafflesia, llijdnora and Cf/linus do not essentially 

 differ from many of the more perfectly developed Pha?no- 

 gauious plants in their vascular structure, I have satisfac- 

 torily ascertained, and there is no sufficient reason to doubt 

 that the same observation may be extended to Brugniaima. 



In my former paper, in treating of the composition of the 



* To tlie third section of llafflesiacefc^ Apodoiiihes and PUosti/les may perhaps 

 be referred. Tliese j^enera indeed aj^ree with Cyluiv.s in their unilocular 

 ovarium with parietal [)laeentation, in their cellular undivided embryo forming 

 the whole mass of the seed, anti in their adherent or semi-adherent ovarium, 

 whose cavity in Filosiijles extends even below the insertion of the braeU^se. 

 The existence of petals, however, in both, and es))ecially in Jpo(laiil/ies,vi\\\ 

 probably be considered as an objection of some weight to their absolute union 

 with Cyiinea- ; and there is even an important dilYerence in their plucentation, 

 the ovula being produced equally over the whole surface of the ovarial cavity, 

 while in Ci/dnua the placenttc are distinct, definite in number, and subdivided 

 into numerous lobes, nearly as in Orchidcce. 



Whether Apodanthes and Pilosfi/les are to be included in the snme genus, as 

 Professor Endlicher (in Gen. p. 70) first conjectured, and as Mr. Gardner lias 

 more recently (in Hooker Ic, new ser. vol. iii, tab. Oil) endeavoured to prove 

 though not imj)robable, must, I think, remain somewhat doubtful so long as we 

 are unaequaiutcd with the male flower of Apodanihes. In the mean time this 

 genus may be distinguished froui niosfyles by the singular insertion of its 

 petals, M-hich also diilV'r remarkably in texture from the quadrilid persistent 

 calyx, and by the two bracteic of tiie flower being seated below the origin of an 

 augidar ovarial cavity, and which, after the falling oil" of the iiarasite, remain 

 attached to the stock.
