Slightly appressed-pubescent or hirsute, 1°-3° high. 
Leaves thin, ovate or deltoid-ovate, 3-nerved, 1’-3’ long, 
acute at the apex, mostly obtuse at the base, dentate, 
the lower slender-petioled, the upper short-petioled or

shorter; pappus of the disk-flowers 4-16, oblong to 
spatulate, fimbriate obtusish or bristle-tipped scales, 
somewhat shorter than or equalling the finely pubescent 
obpyramidal achene. 
In door-yards and waste places, Maine to Ontario, Oregon, 
North Carolina, Missouri, Arizona, California and Mexico. 
Bermuda; Jamaica. Naturalized from tropical America. 
Introduced into Europe as a weed. June-Nov. 
Galinsoga caracasana (DC.) Sch. Bip., similar to this

flowers only half as long as the achene, also tropical Amer- 
ica, has been found in waste grounds in New Jersey and 
Maryland.

[Batpuina Nutt. Gen. 2: 175. 1818. Not Baldwinia Raf. F. 1818.] 
Perennial, caulescent, simple or branched, erect herbs, with alternate entire narrow punctate 
leaves, and large terminal heads of both tubular and radiate, yellow flowers, or those of the 
disk purple. Involucre hemispheric, its small bracts imbricated in several series, appressed, 
or with spreading tips, the outer shorter. Receptacle convex, deeply honey-combed, chaffy, 
the persistent chaff coriaceous or cartilaginous, laterally united, subtending the disk-flowers. 
Rays large, neutral, toothed. Disk-flowers perfect, fertile, the corolla 5-toothed. Anthers 
sagittate at the base. Style-branches with truncate subulate tips. Achenes turbinate, silky- 
villous. Pappus of 7-12 scarious nearly equal scales. [Greek, perhaps referring to the 
immersion of the achenes in the honeycombed receptacle. ]
