 various colors, rotate, slightly irregular, the tube very short, the lower lobe usually nar- 

 rower than the rest. Stamens 2, on either side of the upper corolla-lobe : filaments diver- 

 gent : anther-sacs confluent at the apex. Stigma capitate. Capsule flattened, notched or 

 2-lobed at the apex, loculicidal. Seeds flattened or concave. SPEEDWELL. 



Flowers solitary and axillary, the subtending bracts leaf-like, and similar to the leaves. 

 Pedicels as long as the subtending bracts or longer. 



Corolla longer than the calyx : capsules nearly twice as wide as high. 1. V. Byzanttna. 

 Corolla not longer than the calyx : capsules barely broader than high. 2. V. agretttis.
