(see Fig. 558). The corolla is funnel-shaped. The flowevs are 

 solitary, large. Hyoscyamus (H. niger, Henbane) has a pyxidium 

 (Fig. 557) enclosed in the campanulate, completely persistent, 

 thick- willed calyx. The flowers are slightly zygomorphic, and 

 borne in unipared scorpioid cymes. Scopolia (pyxidium) ; Fnlriana 

 (Heather-like shrub) ; Petunia (slightly zygomorphic flower ; funnel-shaped 

 corolla) ; Nieremberyia ; Brunfelsia (almost a drupe) ; Franciscea; Browallia. 

 Among those with capsular fruits are found the most anomalous 

 fonris, which by their zygomorphic flowers and often didynamous 

 stamens present the transition to the Scropnulariacese : Salpig- 

 lossis ; Schizanthus (lobed petals ; 2 perfect, and 3 rudimentary 

 stamens). 



B. FRUIT A BERRY. Solanum (Nightshade) ; rotate corolla 

 (Fig. 559). The stamens have short filaments, the anthers 

 stand erect, close together round the style, like a cone in the

centre of the flower, and open by pores at the apex (Fig. 560). 

 S. tuberosum (the Potato-plant); the Potato-tuber is a swollen, underground 

 stem; the "eyes" are buds, situated in the axils of its scale-like, quickly- 

 perishing leaves. Lycopersicum resembles Solanum in the flower, but 

 the united anthers open by longitudinal clefts and have an apical 

 appendage. The cultivated species, L. escuJentum (Tomato), has 

 often a higher number than 5 in the flower, and in the fruit several 

 loculi of unequal size. Physalis (Winter Cherry) ; the calyx ulti- 

 mately swells out in the form of a bladder, becomes coloured, and 

 loosely envelopes the spherical berry. Capsicum (Guinea Pepper- 

 plant) ; some species have very large, irregular, rather dry (i - ed, 

 yellow, black) berries, which are unilocular in the upper part. 

 Lijcium (false Tea-plant) ; the corolla is salver- or funnel-shaped ; 

 shrubs ; often thorny. Atropa (A. belladonna, Deadly Nightshade,
