1833. LiNDLEY, John. — (Nixus Plantarum) . 



This was an attempt, in imitation of Agardh and Bartling, to reduce the Natural 

 Orders into groups subordinate to the higher divisions. Such groups were called 

 Nixus (tendencies). The author thi-ew aside the distinctions between perigynous and 

 hj^ogynous insertion as vmcertain and leading to bad gi'ouping ; insisted upon the value 

 of albumen as a primary character, and objected to the general principle that the sec- 

 tions of plants are to furnish their character, and not a character the section. Finally, 

 he mamtained that no sections are capable of being positively defined, except such as 

 depend upon physiological peculiai'ities ; and that all other collections of species, by 

 whatever name they are known, whose distinguishing marks are dependent upon 

 structm-e alone, merely exliibit tendencies to resemblance in certain points, for which 

 tendencies definitions are impracticable. 



Keeping these principles in view, the following was the arrangement : —
