Prostrate, diffusely branched, rooting from the 

 nodes, the branches very slender, sometimes 18' 

 long. Lower and basal leaves slender-petioled, 

 oval or oblong, mostly obtuse, entire, or crenate-

 the nodes, ovate, few-toothed, or entire or some 

 of them 3-parted; heads ovoid-oblong, dense, 

 about 3" long, mostly shorter than the lanceolate 

 reflexed bracts ; bractlets very small ; fruit about 

 i" long, tuberculate.

 Florida and Texas. Summer. 



2. SANICULA L. Sp. PL 235. 1753. 



Perennial or biennial mostly glabrous herbs, with alternate palmately 3-7-foliolate or 

 pinnatifid leaves and sinall yellowish, white or purplish, perfect and staminate flowers in 

 compound generally few-rayed umbels. Umbellets globose. Involucre few-leaved, folia- 

 ceous; involucels small. Calyx-lobes membranous, mostly persistent. Petals obovate, or 

 narrower, incurved at the apex, emarginate. Disk flat. Fruit somewhat flattened laterally, 

 subglobose, covered with hooked bristles in our species. Carpels not ribbed; oil-tubes usu- 

 ally S- [From the Latin, to heal.] 



About 25 species, natives of the north temperate zone. South America and South Africa. 

 Besides the following, about 14 others occur in the southern and western parts of the United States.
