 clasping, entire or toothed, or rarely pinnatifid. Flowers irregular, in terminal 

 racemes or panicles. Calyx deeply 5-cleft. Corolla 2-lipped, elongate, open; 

 the tube often somewhat ventricose above, but not gibbous at the base; upper 

 lip mostly erect, with 2 spreading lobes. Stamens 4; filaments nearly equal; 

 staminodium well developed, spatulate, usually bearded. Styles united; stigma 

 capitate. Capsule usually ovoid, 2-valved. Seeds numerous, wingless. Anther- 

 cells either united or confluent. 



Corolla blue, purple, white, or yellowish, more or less funnelform or salverform. 

 Anthers bearded. 



Plants suffrutescent ; leaves leathery; anthers densely villous; sterile stamens 



usually glabrous. I. FRUTICOSI.

Plant more or less glandular at least in the rather few-flowered inflorescence; 



anthers densely villous; sterile stamen glabrous. II. MOXTAXI. 



Plants glabrous or puberulent, not at aU glandular; inflorescence dense and 

 many-flowered; anthers and sterile stamens sparingly bearded. 



III. GLABRI.

Anthers dehiscent for nearly their whole length or at least at their distal end. 

 Plants not suffruticose at the base. 

 Leaves no^ linear-filiform. 



Corolla decidedly funnelform, i. e., throat much wider than the tube.
