IN NATURAL CLASSIFICATION. 



cases of unisexuality, the irregularity is greater in the female, 

 than ill male unisexuality, and because petals are so intimately allied 

 with the stamens in structure, and perhaps in function. 



The argument is therefore in favour of the polyandrism of 

 Coniferse. 



I was first led to suspect that Conaria is allied to Xanthoxyleas, 

 by the appearance of the young spike, which is like that of 

 Xanthoxylum, and especially the deep colours of the anthers, a cir- 

 cumstance of unusual occurance. 



I would throw the orders with which I am acquainted into the 

 following groups, which are to be hereafter subdivided. 



Ivanunculacese, Papaveraceae, Fumariaceae, Dilleniaceae. Magno- 

 liacese, Anonacece, Schizandrise, Myristiceae, (Nymphasecc'ce, Ne- 

 lumbiacese, Hydropeltidese, these three last, form a very natural 

 aquatic group with Hydropeltis). 



After all, the value of characters must be determined again. Is the 

 excess of albumen, more valuable than adhesion of Calyx. Besides, 

 it must be remembered that the law of representation, if true, 

 would require an agreement between the more perfect cohering forms, 

 granting that to be one type of formation, and the more perfect non 

 cohering another. Thus we should have in Araliaceae the most 

 perfect of their tribe some corresponding point with Ranunculaceie, 

 which may be allowed to so in theirs. The same will be the case sup- 

 posing that Polypetalism, Monopetalism and Apetalism are the three 

 types, for the polypetalous adhering forms must as typical, represent 

 the polypetalous non adhering ones. 



The three primary types. I take to be Polypetalism, Monopeta- 

 lism and Apetalism. 



„ Or Typical Polypetal.e. 



„ Subtypical Monopetalje. 



„ Aberrant Apetal^. (Achlamyde3e==Fungoideafe.) 

 The secondary types require confirmation. Are the groups formed 

 upon the French plan, more consonant with Nature, or, are they not, 

 The primary types may thus be considered. 



Typical character, distinction of parts 



Subtypical ditto, adhesion of ditto 



Aberrant ditto, suppression of ditto 

 Tested by this, the perigynous type goes for nothing, for its consti-
