cent: capsules depressed, 1.5-2 mm. long.

20. SOPHRONANTHE Benth. 
Annual or perennial rigid caulescent herbs, with rough-pubescent foliage. Leaves 
opposite : blades entire or toothed, sessile. Flowers solitary in the axils, short-peduncled 
or nearly sessile. Calyx sessile in 2 bractlets : sepals 5, nearly distinct. Corolla white or 
purplish, 2-lipped. Stamens 2, included. Staminodia filiform, capitate at the apex. 
Anther-sacs parallel, contiguous. Capsule somewhat elongated, acuminate. 
Leaf-blades linear, entire: corolla-tube about twice as long as the sepals, 1. S. hispida. 
Leaf-blades ovate, oval or oblong, toothed : corolla-tube barely surpassing the sepals. 2. S. pilosa. 
1. Sophronanthe hispida Benth. Stems hispidulous, 0.5-2 dm. tall, usually
