33. CYNOSCIADIUM DC. Mem. Omb. 44. pi. n. 1829. 



Glabrous slender branching annuals, the lower and basal leaves mostly linear and entire, 

 those of the stem mainly divided into few linear segments. Involucres and involucels of 

 several subulate or narrowly linear bracts, sometimes deciduous. Flowers small, white, in 

 terminal and lateral compound umbels. Calyx-teeth short, persistent. Fruit ovoid, or oblong, 

 nearly terete, glabrous, strongly ribbed, the lateral ribs the larger; oil-tubes solitary in the 

 intervals and 2 on the commissural side of each carpel. Seed-face flat. Stylopodium conic. 

 [Greek, dog-celery.] 



Two known species, natives of the southern United States, the following typical.
