[OsMORRHIZA Raf. loc. cit. 1818.] 
Perennial herbs from fleshy clustered thickish roots, 
with decompound leaves, and loose few-rayed umbels 
of white flowers. Involucre and involuccls of few narrow bracts, or none. Calyx-teeth ob- 
solete. Petals incurved at the apex. Stylopodium small, conic. Fruit narrow, linear or 
oblong-linear, short-beaked, compressed, more or less bristly along the ribs, attenuated at 
the base. Carpels 5-angular, slightly flattened dorsally, the ribs acute and nearly equal; 
oil-tubes obsolete or none. [In honor of George Washington. ]

fruit about 6’” long, about 1/’ wide; style and stylo-
