The genus can be easily distinguished from the other members of the subfamily Crotonoideae by its bright, colourful petals, as suggested by Balakrishnan and Chakrabarty (1991), and by its 3 or 5 connate stamens (Yu, 1989). Morphologically, T. eberhardtii resembles T. viridissimus (Kurz) Airy Shaw, but it can be differentiated through its monopodial inflorescence branching pattern, white petals, and indistinctive style (Yu &amp; Van Welzen, 2020).</p></div>	https://treatment.plazi.org/id/03DB87A40309FFC4FC90F8BA0619DB5F	Public Domain	No known copyright restrictions apply.
