Gen. Char. Flowers (see fig. 1 .) uniform, and nearly regular, 

 almost all perfect and prolific. Margin of the calyx obsolete. 

 Corolla (see fig. 1.) of 5 roundish, or inversely egg-shaped petals, 

 with inflexed points, all very nearly equal. Filaments (see fig. 1.) 

 5, thread-shaped, about as long as the corolla. Anthers roundish. 

 Germen (see fig. 2.) inferior, almost round, somewhat compressed. 

 Styles (see fig. 2.) at first shorter than the stamens, nearly upright, 

 subsequently elongated, thread-shaped, refiexed ; greatly swelled 

 at the base, and subtended by a thin, roundish, wavy floral re- 

 ceptacle (see fig. 2.) . Stigmas blunt. Fruit egg-shaped or nearly 

 orbicular, solid, slightly compressed, flattened at the sides, crowned 

 with the withered floral receptacle, and spreading styles. Carpels 

 ( seeds of Linn.,/ (fig. 3.) egg-shaped, with 3 filiform, equal ridges , 

 of which the lateral ones are marginal. Interstices with single 

 pitta, except the outermost, which have sometimes 2 or 3. Seed 

 very convex, flattish in front. Involucrums none. Flowers white 

 or greenish. 



The obsolete calyx; roundish entire petals, inflexed at the 

 point ; roundish, double fruit, contracted at the sides ; the carpels 

 with 5 filiform, equal ridges, of which the lateral form a margin ; 

 the furrows between the ribs with single vittae, except the outer- 

 most, which have sometimes 2 or 3 ; the very convex seed, flattish 

 in front ; and the absence of a general and partial involucrum ; will 

 distinguish this from other genera in the same class and order. 



One species British. 



APIUM GRAVE'OLENS. Smallage Parsley. Wild Celery.

 nate ; leaflets wedge-shaped, cut and toothed at the apex.
