 ovary, deciduous. Petals 4, clawed, often lobed or cleft. 

 Stamens normally 8, those opposite the petals often 

 sterile, rudimentary or wanting ; anthers oblong or 

 linear, fixed by the base. Ovary 4-celled ; style elon- 

 gated ; stigma 4-lobed, the lobes spreading. Capsule

 glaucous, 3-15 dm. high, simple or somewhat branched, rather 

 stout and rigid ; leaves broadly ovate to linear, repand-dentate ;

 claw; filaments all perfect, with a densely hairy scale on each 

 side at base ; capsule 1-2 cm. long, stout, sessile, 4-angled, some-
