Calyx of 2 small and scarious sepals, deciduous. Co- 

 rolla as in Dicentra, but the petals all firmly coalescent 

 into an ovate-cordate body, which is marcescent-persistent 

 and perfectly incloses the mature pod. Stamens as in Di- 

 centra, except that the filaments of each set are united 

 nearly to the top into a lanceolate scarious synema. Ovary 

 linear-lanceolate, one-celled, with two parietal placentae : 

 style subulate : stigma flattened and dilated contrary to the 

 placentae, two-lobed. Ovules 4 to 6 on each placenta, alter- 

 nately inserted in a single series, horizontal, nearly anatro- 

 pous ; the raphe superior. 



Capsule siliquaeform, lanceolate, tipped with the persist- 

 ent style and stigma, always covered by the marcescent 

 corolla, inclosed within the inner petals and the stamineal 

 sheath, two-valved, the intervalvular filiform placenta; form- 

 ing a replum. Seeds 8 to 12, alternately inserted on each 

 placenta in a single series, horizontal, obovoid-reniform, na- 

 ked (not crested at the raphe or hilum); the black crusta- 

 ceous testa smooth and shining. Albumen fleshy, reniform- 

 incurved. Embryo small, cylindrical, in the hilar curvature 

 of the albumen. 



Herb biennial, with elongated branching stems, climbing 

 gracefully by its tendril-like young petioles ; the leaves al- 

 ternate, 3 - 4-ternately or pinnately decompound, with a
