Description:  "Plants sometimes annual but probably enduring often for more than one year, erect, sparsely or much branched, generally 50 cm high or less, sparsely or densely hispidulous; leaves mostly small, divided into very numerous, small, narrow, obtuse and apiculate segments; bracts of the involucre much divided and resembling leaves; umbels many-flowered, usually rather open, as much as 15 cm. broad but usually much smaller, the rays stiff, very unequal; bractlets of the involucels linear; pedicels in fruit usually conspicuously elongate and mostly 5-8 mm. long; fruit about 5 mm. long, with dense rows of stout pale spines along the winged angles, the spines barbate at the apex"  (Standley et al., Part VIII, Nos. 1-2; pp. 38-39).

Habitat/ecology:  In Guatemala (native), "moist or dry, often rocky, brushy or open fields and hillsides, sometimes in meadows in Alnus forest, in gravel along streams, or a weed in waste or cultivated ground, 1,000-3,000 meters, most frequent at middle or higher elevations. A rather common plant in meadows of the highlands, often plentiful in overgrazed areas, since no animals eat the foliage"  (Standley et al., Part VIII, Nos. 1-2; pp. 38-39).

Propagation:  Seed.  "The burlike fruits adhere closely to clothing and to the hair of animals, thus aiding in wide dispersal of the seeds"  (Standley et al., Part VIII, Nos. 1-2; pp. 38-39).

Native range:  Central and South America (GRIN).
