Herbs 140 



140. Calyx gamosepalous. Petals G, sometimes 7. Sta- 

 mens 6, 7, or twice as many 143 



Calyx polysepalous, with 2 or 3, sometimes early de-

141. Petals thick, reniform or hooded, gland-like bodies. 

 A simple and naked stem terminated by a small, simple, or 

 compound raceme of yellowish-green flowers, and, a little

Petals not gland-like, but flat and oval, or oblong. 

 Leaves orbicular, roundish-kidney-form, or broadly cordate, 

 incisely lobed. Stems 1-leaved, or 2-leaved, the leaf in the

 near the base. Flowers either in a terminal c}nne or solitary,

 much longer than the sepals. Stamens 6. Berry 2- to 4-seed-

Anthers not opening by uplifted valves. Petals 6 

 or 9. Stamens 12 and more (to 18). Berry pulpy, many-
