Hyoscya 



structure 



cruciform 



to which they are attached by a central axile line, becoming 

 lunately expanded in the middle of each cell as in Phy salts ; I 

 have found the placentae on the contrary to be thick and fleshy, 

 both closely adnate with the dissepiment, forming one cyhndrical 

 column that fills the greater portion of the central space of the 

 ovarium ; the embryo is also shown too thick in proportion, and 

 the cotyledons are not incumbent as there exhibited, but accum- 

 bent after the manner almost universally seen in this family : 

 some of the figures there truly represent the corolla as having an 

 imbricated aestivation, which however is erroneously described in 

 the text, as in the descriptions of all other authors, as being pli- 

 cated : there is no indication there represented of the remarkable 

 apical gland in the summit of the ovarium. 



I have annexed the specific character of a species which I 

 found growing in Kew Gardens, and which appears nowhere 

 given.
