116 DIDYNAMIA— ANGIOSPERMIA. Bartsia. 



Corolla of 1 petal, inferior, mostly irregular, segments im- 

 bricated in the bud, deciduous. 



Stamens generally 4, 2 longer and 2 shorter, rarely equal : 

 sometimes but 2. 



Germen with many seeds, in 2 cells ; style 1 ; stigma 2- 

 lobed ; rarely undivided. 



Capsule, (very rarely a Berry,) of 2 cells, with 2 or 4 valves, 

 which are either undivided or cloven ; the partition either 

 double, originating from the inflexed margins of the 

 valves ; or simple, either parallel to the valves and undi- 

 vided, or contrary to them and separable into 2 parts. 

 Receptacles central, attached to the partition, sometimes 

 separating finally from it. 



iSeer/5 numerous, albuminous; the £?«irj/o internal, straight; 

 Radicle directed towards the scar. 



Herbs, sometimes sJinibs, with for the most part opposite 

 leaves. Iiiflorescence various. Stipulas none. 



Mr. Brown justly reprehends Jussieu for making the di- 

 stinction of a parallel or transverse partition in the fruit 

 absolute, thus splitting one natural order into two. It is 

 like making a character "give a genus, not a genus a 

 character," one of the great causes of so many unnatural 

 genei-a in Zoology as well as Botany. An American 

 writer has remarked also that " the recent custom among 

 Geologists, of cutting up and subdividing, seems to be 

 upon the point of ruining the simplicity of the Wernerian 

 arrangement, as the same custom among Botanists has 

 already nearly ruined the Linnaean system of vegetables." 

 Van Rensselaer'' s Suri>ey of the Erie Canal, ]}. 17. I hope 

 this last remark is not correctly true, and that such in- 

 judicious attempts will be resisted by those who possess 

 the talent of scientific combination ; which, in Natural 

 History, is full as necessary as that of observation and 

 discrimination, and much less common.
