Anisodus. 



In noticing this genus {huj. oper. iii. 166), I had arranged it 

 near Atropa, on account of the analogy offered by the structure 

 of the corolla in that genus, and of the apparently fleshy peri- 

 carpial covering of its immature fruit ; since that period I have 

 had an opportunity of examining its ripened capsule, and now 

 find that it must take its place among the Hyoscyamea, after 

 Thinogeton, and thus bordering upon Atropa. The ovarium is 

 small, conical, and half invested below by a very thick fleshy 

 yellow disc ; its apical gland, in the young state, is not so strongly 

 developed as in Hyoscyamus, though it is distinctly visible, and 

 may be considered, in like manner, as an extension of the base 

 of the style : as the process of fructification advances, the basal 

 disc disappears, and the lower portion of the ovarium takes a 

 rapid increment both in length and diameter, and the pericarpial 

 covering becomes more and more attenuated, until at length it 

 forms a thin and brittle shell, composed of a loosely cohering epi- 

 carpial and an endocarpial pellicular integument with a thin semi- 

 ligneous mesocarpial intervening plate : the opercular apex is 

 smaller, in proportion, than in Hyoscyamus, flatter, thick and 

 coriaceous, somewhat 4~lobed, and bursts away from the lower 

 shell by a ruptured circumscissile line of dehiscence, as in the 

 genus last mentioned. The border of the corolla is not plicate, 

 as stated by Endlicher and other authors, but on the contrary, 

 distinctly imbricate in gestivation. The following may be con- 

 sidered as an outline of its generic features.
