Seeds more fimbriate than in C. europcea. Styles (in Engelmann's named examples of 

 C. plcwiflora} short, less than half as long as the stigmas. C. brevistyla is not 

 merely"'' too near" C.planiflora as both Engelmann and Boissier suggest; it is the 

 same thing. 



ORDER Oil. SOLANACEJE. (By C. B. Clarke.) 



Herbs or shrubs. Leaves alternate, often in unequal pairs, rarely clustered, 

 never opposite ; entire, lobed or pinnate ; stipules 0. Cymes lateral, or terminal, 

 axillary or extra-axillary, or pedicels solitary or clustered ; bracts and bracteoles 

 0. Flowers regular, hermaphrodite (in Withania coagulans dioecious). Calyx 

 inferior, 5-, rarely 3-7-merous, in Nicandra 5-partite ; in fruit usually per- 

 sistent, often much enlarged. Corolla funnel-shaped campanulate, or rotate, 

 often plaited ; lobes 5 (in Datura sometimes 10), or limb subentire. Stamens 

 5, on the corolla-tube ; anthers ovate or oblong, dehiscing by apical pores or 

 longitudinally. Ovary 2-celled, or imperfectly 1- or 4-celled, in Nicandra 3-5- 

 celled ; style linear, stigma capitate or very shortly lobed ; ovules very many, 

 on prominent peltate placentas. Fruit baccate or capsular, indehiscent circuni- 

 sciss or valvular, usually 2-celled, many-seeded. Seeds compressed, discoid or 

 subreniform, embryo peripheric ; or (in Nicotiana) seeds scarcely compressed, 

 embryo straight. Species 1250 in the warmer parts of the whole world.
