166 Mr. J. Miers on several genera hitherto placed in Solanaccse. 



Tribe 7. HyoscyamecB. 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, 

 and bursting longitudinally in front near the 

 margin : ovarium 2-celled, and singularly sur- 

 mounted by a fleshy epigynous gland, which is 

 either small and stylobasic, or else enveloping 

 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. Airopea. 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. Solandrecc. 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 

 epipetalous, but sometimes arising from the out-

side of a free ring, attached to the base of the yjuanulloa, 

 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 Hetercmthia) : stamens 

 didynamous, somewhat inflected at the apex, 

 with one pair shorter ; anthers unilocular and 

 hippocrepiform, as in the Verbascete 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 Scrophulai'iacea, as here de- 

 fined, evidently constitute an alliance, bound together by very 

 striking and peculiar characters, distinguishable in the sti-uctvire 

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