However, they can be distinguished by the leaflets with actinodromous, flower with 5–lobed calyx, violet corolla and legume with constricted margin in M. grandiflorus vs. leaf with brochidodromous venation in leaflets, flowers with 4–lobed calyx, pink petals and legume with a straight margin in C. brasiliensis.</p> </div>	http://treatment.plazi.org/id/038E87C1995C5F2704DFEFCDFCE874EB	Public Domain	No known copyright restrictions apply.

The representatives of monadelphous androecium belong to the Ingeae tribe, while those with dialystaminous androecium may belong to the Mimoseae or Acacieae tribes. The androceu-related characteristic used to separate species is the number of stamens; the species of Mimoseae are isosstaminous or diplostaminous whereas those belonging to Acacieae have polistaminous flowers.

Paraíba: Maturéia, Pico do Jabre, 800 m elev., 05 October 2018, fl., Aureliana Gomes 3017 (HACAM).</p> <p>Distribution and ecology:— It has a wide distribution in the American continent (Ramalho; Rosa, 2010). In Brazil, this species presents itself in a greater proportion in the Northeast region, followed by the North, CentralWest, Southeast and South regions of the country, associated with the domains of the Amazon, Caatinga, Cerrado and Atlantic Forest (BFG 2018, Mendonça et al. 2019).</p> <p>Phenology:— Registered with flowers in October.</p> <p>Taxonomic discussion:— Stylosanthes viscosa can be recognized, mainly, by the subshrubby habit, by the lateral stipules and 3–foliolate leaves, inflorescence in spike, yellow corolla flowers and loment fruits. Regarding the species of Papilionoideae, it shares, among other species of the group, the presence of glutinous branches, stipule adnate to the petiole and 3–foliolate leaves. However, it is distinguished from other species with 3–foliolate leaves due to the presence of a stipule adnate to the petiole.</p> </div>	http://treatment.plazi.org/id/038E87C199425F3904DFEA7BFDE37764	Public Domain	No known copyright restrictions apply.
