 arising from between the petioles. Calyx pubescent without, the tube angled, the 

 3 segments as long as the tube or longer, inflexed in the bud. Corolla none. 

 Stamens 12 ; filaments longer than the anthers. Ovary adnate to the calyx-tube. 

 Styles united; stigmas terminal. Capsules inferior, angled. Seeds plump. [The 

 ancient name, meaning obscure. J 



Calyx-segments lanceolate-acuminate, longer than the tube, not reflexed. 



Calyx-segments slightly longer than the tube, the tubular portion 4-8 mm. long ; 



species mainly Alleghenian. i. A. Canadense. 



Calyx-segrnents much longer than the tube, the tubular portion 10-20 mm. long; 

 species campestrian. 2 . A. acuminatum.
