Cephalanthus salicifolius is a species of flowering plant in the family Rubiaceae. [5] [6] [2] Common names include Mexican buttonbush, mimbre, botoncillo, and Jazmin blanco. [7] Its native range extends from the banks of the southernmost stretch of the Rio Grande in Cameron and Hidalgo Counties of Texas [8] through much of Mexico from Coahuila to Oaxaca; a disjunct population exists in Honduras. [9] [10]
Like other species in its genus, Mexican buttonbush grows in the wet soils of riparian zones, swamps, and pond margins. [11] It is a deciduous shrub or small tree, reaching a height of 8–18 ft (2.4–5.5 m) and a width of 4–10 ft (1.2–3.0 m). [7] The oblong leaves reach 12 cm (4.7 in) in length and 23 mm (0.91 in) in width. [9] The white flowers are produced from March to July; the fruit is a collection of brown nutlets. [12]
