*Sida rhombifolia Linnaeus var. rhombifolia. Common name: Arrowleaf Sida, Axocatzin. Phenology: Apr-Oct. Habitat: Roadsides, fields, gardens, disturbed areas. Distribution: Southeastern North America west to TX, south through Mexico, Central America, and n. South America; West Indies; the original distribution of this species is uncertain, but Fryxell & Hill (2015m) and POWO (2024) suggest it is native to the Old World tropics.
Origin/Endemic status: Paleotropics
Taxonomy Comments: Verdcourt (2004) discussed variation in this taxon, and suggested that "studies throughout the entire range of the species will necessitate recognition of more than one species". He recognized six varieties in e. Africa, aside from the Linnaean var. rhombifolia (with type in Jamaica).
