LEPTAXIS YOUTH-ON-AGE

slightly irregular; segments 5, ascending. Petals subulate, persistent. Stamens 3, opposite 
the upper 3 sepals. Ovary superior, |-celled; placentae parietal. Capsule with 2 long 
beaks, attenuate at base. (Apparently Gk. leptos—slender, -axis; referring to the ra-

Ovary 1 /5—1 /2 inferior, |-celled; placentae 3, parietal; styles 3, short. (Gk. lithos— 
a stone, phragma—an enclosure; probably referring to the hard capsule.)
