Schizocarps ± ovoid, 9–14 × 10–16 mm; mericarps: apex acuminate, surface uniformly stellate-pubescent and with simple hairs on abaxial margins. Seeds 3 per mericarp, 3 mm, reticulately scabridulous. 2n = 28.

Abutilon abutiloides has been confused with A. californicum Bentham and A. berlandieri; the three species are distinct (P. A. Fryxell 1988). It is found in extreme southern Texas and more commonly in west-central and southeastern Arizona.
