Description
Generally, in the group Chameacrista it includes trees, shrubs, or herbs. The leaves are evenly 1-pinnate with conspicuous gland(s) on the petiole or rachis. The flowers are either solitary or clustered in axillary racemes or terminal panicles, perfect. The calyx has an inconspicuous tube, 5 lobed, equally imbricate, and often unequal. There are 5 petals and are a little unequal. The stamens 5-10, are often unequal and some are sterile or imperfect. The anthers are basifixed and opening by 2 apical pores. The legume is few-to many-seeded, often septate, and exceedingly variable. Including Chamaecrista Moench, Ditremexa Raf., Emelista Raf. [1]
Specfically, for Chameacrista fasciculata, the species is an annual herb, growing 1.5-6 dm tall from the taproot. The stems and branches are glabrous to more commonly densely puberulent with incurved trichomes and occasionally also with villous trichomes to 2 mm long. The leaves are sensitive with a sessile, depressed, saucer-shaped gland, 0.5-1.5 mm in diam. near the middle of the petiole. Leaflets 12-36, linear-oblong, 1-2.5 cm long, 2-6 mm wide, inequilateral; stipules persistent, striate. Inflorescence are 1-6 flowered axillary fascicle. Pedicels grow up to 1-2 cm long. Sepals are lanceolate in shape, growing 9-12 mm long, and are acute. Petals are bright yellow in color, almost equal, growing 1-2 cm long; stamens 10, unequal, growing 10-13 mm long. The legume are elastically dehiscent, growing 3-7 cm long, and 5-7 mm broad, and are glabrate or appressed-puberulent to villous. [1]

Ecology
Seed dispersal
This species disperses by being consumed by vertebrates (being assumed). [2]
