166 Mr. J. Miers on sevei-al genera hitherto placed in Solaiiacese. 



Atropa, 

 Nicandra, 

 CliocarpuSy 

 f Anisodus, 

 Mandragora, 

 Lycium. 



Tribe 7. Hyoscyamea. Corolla tubular, more or less 

 expanded in the mouth in a campanular form, 

 with the border divided into 5 equal rounded 

 lobes: stamens 5, equal; anthers 2-lobed, affixed 

 to a narrow dorsal connective above, free below, Hyoscyamus, 

 and bursting longitudinally in front near the Scopolia, 

 margin : ovarium 2-celled, and singularly sur- yPhysoclcena, 

 mounted by a fleshy epigynous gland, which is Cacahus, 

 either small and stylobasic, or else enveloping Thinogeton. 

 the upper moiety of the ovarium : fruit an ex- 

 succous berry, which sometimes bursts by a cir- 

 cumscissile line on the margin of the gland : em- 

 bryo terete, annular, and somewhat spiral. 



Tribe 8. Atropece, Corolla tubular, more or less 

 campanular, with a border divided into 5 equal 

 rounded lobes, which are imbricate in aestiva- 

 tion : stamens 5, equal ; anthers ovate, 2-lobed, 

 lobes laterally adnate, reversed in Atropa by the 

 deflexion of the filaments : fruit baccate, 2- or 

 5-celled, fleshy, often somewhat exsuccous : em- 

 bryo terete, nearly perispherical. 



Tribe 9. Solandrece. Corolla generally with an elon- 

 gated, straight, rarely a short tube, in no degree 

 plicated in bud, border 5-cleft into more or less 

 rounded equal lobes : 5 equal stamens, generally Solandray 

 epipetalous, but sometimes arising from the out- Marckea, 

 side of a free ring, attached to the base of the )>Juanulloa, 

 corolla ; anthers oblong, 2-celled, cells parallel Sarcophysa, 

 and adnate upon a dorsal connective, and burst- Ectozoma. 

 ing longitudinally in front : fruit a fleshy 2-locu- 

 lar berry, and seeds with a nearly straight terete 

 embryo, with a lax testa, as in the Cestrinece. 



Tribe 10. Brunsfelsiece. Corolla with a more or less" 

 elongated tube, somewhat ventricose below the 

 contracted mouth, border divided into 5 nearly 

 equal segments, their aestivation being decidedly 

 imbricative (unknown in Heteranthia) : stamens 

 didynamous, somewhat inflected at the apex, xj^ 



with one pair shorter; anthers unilocular and ^ tt . .i-* 



hippocrepiform, as in the Verbascea and the Du~ 

 boisiece : style slender : stigma small, bilobed, 

 and simply clavate, or with the lobes somewhat 

 gaping : fruit either capsular or baccate, with a 

 nearly straight embryo. 



The Solanacece, AtropacecE and Scrophulariacece, as here de- 

 fined, evidently constitute an alliance, bound together by very 

 striking and peculiar characters, distinguishable in the structure 

 of their corolla and ovarium, but more especially in that of their 



Brunsfelsia, 



Heteranthia.
