General/Distribution: A genus with about 150 species distributed in the tropics and subtropics of both the hemispheres. It is represented by 18 specific and intraspecific taxa in Pakistan.
Comment/Acknowledgements: Doubtful species

Abutilon persicum (Burm. f.) Merr. has been recorded from N.W. Province (Masters 1874) and from Sind (Blatter et al 1929). Presently no specimen of this species is traceable and its occurrence seems to be doubtful.

Perennial herbs to shrubs, rarely small trees (not in Pakistan) covered with stellate hairs, sometimes mixed with simple hairs. Leaves petiolate, stipulate, ovate or cordate, toothed, angled or lobed. Flowers axillary or terminal, solitary or in terminal racemes or panicles by the reduction of leaves. Expicalyx absent. Calyx 5-lobed. Corolla yellow to orange-yellow. Staminal column divided at the apex into many filaments, included. Carpels 5-many loculed, each locule 2-9 ovuled; stigmas capitellate-capitate; style branches as many as carpels, filiform-clavate. Fruit subglobose, truncate or cylindric, dehiscent schizocarp; mericarps acute to acuminate or obtuse, 2-9 seeded Seeds ± reniform glabrous or hairy.
