1. DICLINOUS EXOGENS. 



Tin' plants thus named never, or at le 

 Bowers, but consist of -; 11 which thi 



one k i : j< 1 of flower, and the pistil in another. Thej ap] 

 Dearest approach that can be found t<> Gyium 



atal Alliance mighl in fact be referred, it" the • 

 i:t the ovules naked to the action of the pollen. It 

 erlook, on the one band, the cl<

 the Order of Birchworts ; <>r. on 1 1 1* • other, 1 1 » ■

These and Bimilar Orders must be regarded as th< sirupl 

 structure which Diclinous Exogei -: sent, their conditi

 Diclinous Chenopods, which form an exception to I

 whose organisation is the highest, Buch a> Menisj 

 Papayals .11 find that all the others have also 



less manifest description. Thus Spurges, J 

 the Perigynous Rhamnads, Anacards, and .' 

 Nutmegs stand on the limits of the Hypog 

 while the Epigynous Sandalworts and i. 

 the Diclinous Eelwingiads and Cucurbits. 



These facts show, that, although in one direction 

 may be perceived, as that of which u-<- I

 by the Diclinous to tin- bisexual Alliances and I 

 ' It would be possible to break up the Diclin 

 Perigynous, and Epigynous clusters; and t 

 such a distribution would have been i 

 posed : and perhaps that view is • 

 whether the advantages of that plan would
