Tribe 7. Hyoscyamee. Corolla tubular, more or ome 
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- + Physochlena(?), 
mounted by a fleshy epigynous gland, which is {| Cacabus, 
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. “J 
Tribe 8. Atropee. Corolla tubular, more or less) 
campanular, with a border divided into 5 equal | Atropa, 
rounded lobes, which are imbricate in exstiva- | Nicandra, 
tion : stamens 5, equal ; anthers ovate, 2-lobed, Cliocarpus, 
lobes laterally adnate, reversed in Atropa by the { Anisodus, 
deflexion of the filaments : fruit baccate, 2- or | Mandragora, 
5-celled, fleshy, often somewhat exsuccous : em- | Lycium. 
bryo terete, nearly perispherical. 
Tribe 9. Solandree. 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 | Solandra, 
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 Cestrinee. y 
Tribe 10. Brunsfelsiee. Corolla with a more or less) 
elongated tube, somewhat ventricose below the 
contracted mouth, border divided into 5 nearly 
equal segments, their zstivation being decidedly 
imbricative (unknown in Heteranthia) : stamens | B Isi 
didynamous, somewhat inflected at the apex, gh minis 
with one pair shorter; anthers unilocular and (17 @"etscea, 
hippocrepiform, as in the Verbascee and the Du- | //@teranthia. 
boisiee : style slender: stigma small, bilobed, 
_and simply clavate, or with the lobes somewhat 
gaping : fruit either capsular or baccate, with a 
nearly straight embryo. ve 
The Solanaceae, Atropacee and Scrophulariacee, as here de- 
fined, evidently constitute an alliance, bound together by very 
striking and peculiar ¢ aracters, distinguishable in the structure 
of their corolla and ovarium, but more especially in that of their
