Summary 6

Sida rhombifolia (arrowleaf sida) ( Sanskrit : atibalā अतिबला ) is a perennial or sometimes annual plant in the Family Malvaceae, native to the New World tropics and subtropics. Other common names include rhombus-leaved sida, Paddy's lucerne, jelly leaf, and also somewhat confusingly as Cuban jute, Queensland-hemp, and Indian hemp (although S. rhombifolia is not related to either jute or hemp).
