 by minute or obsolete bractlets : corolla whitish, 10-12 mm. long ; tube glandular-pubes- 

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

 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.
