 by two lamellar lobes^ whose inner surfaces are covered with

These differences in structure are small, and not to be discerned 

 in the dried state^ and therefore of themselves scarcely afford 

 sufficient ground for a generic distinction; but combined with a 

 very peculiar habit^ easily distinguishable from that of Oestrum, 

 they justify me in recalling the recommendation suggested, as 

 above quoted^ and in reinstating the genus, as proposed by Mr. 

 Bentham, with the following amended character : not having 

 seen the seed, I copy the description of it and the fruit wholly 

 from that of Endlicher. ^Gen. W 3867. In coming to the 

 above conclusion, it ought to be stated at the same time, that 

 H. tomentomSy with its small calyx and the paucity and smallness 

 of its bracts, does not sensibly differ in habit from many species 

 of Cestrum, while on the contrary C, bracteatum and C. organeiise 

 possess the large involucrating bracts that characterize most

thamnus, I have added it, as another species of this genus, and 

 others may perhaps also be found to belong here.
