placentas presents the large circular cavity of the capsule, as if merely one-celled, 
with two hemispherical valves! Seed with a corneous, large albumen; embryo 
straight, minute, central, not half the length of the albumen. Annuals with 
bipinnatifid leaves, and the flowers in loose racemes. 
E. *pantcutaTa. ©. Flowers in loose terminal panicle; stem viscid; uppermost leaves pinnatifid, 
segments of the calyx oval, obtuse. 
About one to two feet high, somewhat hairy and viscid. The leaves bipinnatifid ; 
the segments short, and toothed bluntly. Flowers small, yellowish-white, rather more 
than the length of the calyx, disposed in loose, naked, terminal racemes, with long 
peduncles. Calyx cup-shaped, increasing with the fruit; the segments oval and 
obtuse. Corolla pubescent, tubular-campanulate, shortly 5-cleft, before opening, with 
three of the segments external. Stamens equal, with slender filaments; anthers 
small and oval; style longer than the germ, with a very short bifid stigma. Capsule 
depressed, globose, apparently 1-celled, each of the placentas becoming adnate to the 
sides of the valves, with about four rugose seeds, two to four other even, elliptic seeds 
concealed behind the placental lamina, one or two behind each. The rugose 
epidermis of the seed swells up into a pulpy mass on being moistened.
