was the first to separate them as a distmct genus, on account ot 

 their entire leaves and their terminal corymbose purple flowers, 

 but as in his generic character no feature appeared to mdicate 

 any difl"erence from Hyoscyamus, either in the structure of the 

 flower or the fruit, they have been retained m this latter genus by 

 all succeeding botanists. M. Decaisne in describmg an Indian 

 species perceived the difference of its habit from that ofHyoscy- 

 amm, and adopted it as the type of a new genus, under the name 

 of Belenia, but this suggestion has in like manner been disre- 

 garded. I have noticed however the following circumstances 

 that seem to warrant the restoration of this genus. In Physo- 

 chl^na the apical gland is proportionally much smaller and far less 

 conspicuous than in Hyoscyamus, for the ovarium t)"°g ^^r^ 

 conical, it covers only the extreme upper portion beneath the 

 base of the style, and is distinguishable from the rest of its sur- 

 face by its lurid purple colour : it offers also a larger and more 

 conspicuous hypogynous, fleshy, yellow disc, which is somet mes 

 scarcdy disce/nibf/ in the other genus. Besides these po mt« of
