Family Malvaceae

Herbs, shrubs , or less often trees ; indumentum usually with peltate scales or stellate hairs . Leaves alternate, stipulate , petiolate ; leaf blade usually palmately veined, entire or various lobed . Flowers solitary, less often in small cymes or clusters , axillary or subterminal , often aggregated into terminal racemes or panicles, usually conspicuous , actinomorphic , usually bisexual (unisexual in Kydia) . Epicalyx often present, forming an involucre around calyx, 3- to many lobed. Sepals 5, valvate , free or connate . Petals 5, free, contorted, or imbricate, basally adnate to base of filament tube . Stamens usually very many, filaments connate into tube; anthers 1-celled. Pollen spiny . Ovary superior, with 2-25 carpels, often separating from one another and from axis; ovules 1 to many per locule; style as many or 2 × as many as pistils, apex branched or capitate. Fruit a loculicidal capsule or a schizocarp, separating into individual mericarps, rarely berrylike when mature (Malvaviscus) ; carpels sometimes with an endoglossum (a crosswise projection from back wall of carpel to make it almost completely septate . Seeds often reniform , glabrous or hairy , sometimes conspicuously so.

About 100 genera and ca. 1000 species: tropical and temperate regions of N and S Hemisphere; 19 genera (four introduced ) and 81 species (24 endemic, 16 introduced) in China.

Molecular studies have shown that the members of the Bombacaceae, Malvaceae, Sterculiaceae, and Tiliaceae form a very well-defined monophyletic group that is divided into ten also rather well-defined clades, only two of which correspond to the traditional families Bombacaceae and Malvaceae. Some of the remaining groups are included entirely within either of the remaining families but others cut across the traditional divide between the Sterculiaceae and Tiliaceae. A majority of authors , most notably Bayer and Kubitzki (Fam. Gen. Vasc. Pl. 5: 225-311. 2003), has favored including everything within a greatly enlarged Malvaceae, and treating the individual clades as subfamilies. The alternative view is that the individual clades should be treated as a series of ten families: Bombacaceae (Bombacoideae), Brownlowiaceae (Brownlowioideae), Byttneriaceae (Byttnerioideae), Durionaceae (Durionoideae), Helicteraceae (Helicteroideae), Malvaceae (Malvoideae), Pentapetaceae (Dombeyoideae), Sparrmanniaceae (Grewioideae), Sterculiaceae (Sterculioideae), and Tiliaceae (Tilioideae) (Cheek in Heywood et al. , Fl. Pl. Fam. World. 201-202. 2007) . For the present treatment, we prefer to retain the familiar, traditional four families, so as to maintain continuity with the treatments in FRPS, and to await a consensus on the two alternative strategies for dealing with the very widely accepted clades.

The traditional Malvaceae coincides exactly with one of the major clades. The only possible problem is the relationship with the Bombacaceae, which also has primarily 1-loculed anthers, and some authorities have suggested that the Bombacaceae should be included within the Malvaceae.

Members of the Malvaceae are important as fiber crops (particularly cotton, Gossypium) . Young leaves of many species can be used as vegetables, and species of Abelmoschus and Hibiscus are grown as minor food crops. Many species have attractive flowers and an ever-increasing selection is grown as ornamentals . Several have been cultivated for a very long time, particularly species of Hibiscus, and some of these are not known in the wild.[1]

Genus Sida

Herbs perennial or annual , subshrubs or shrubs , to 2 m , most parts with stellate , simple and/or glandular hairs . Leaves simple; stipules threadlike to narrowly lanceolate; leaf blade entire (sometimes lobed ), margin usually dentate , without foliar nectaries. Flowers solitary or paired , axillary or subterminal , often in axillary or terminal racemes or panicles, rarely in umbels or glomerules . Epicalyx absent. Calyx campanulate or cup-shaped, 5-lobed, often 10-ribbed basally and plicate in bud. Corolla mostly yellow, rarely white or ± orange [or rose or purplish], sometimes with a dark center. Petals 5, free , basally connate . Filament tube pubescent or glabrous , with many anthers at apex. Ovary 5-10-loculed; ovules 1 per locule, pendulous; style branches as many as carpels; stigma capitate. Schizocarp ± disk-shaped or globose ; mericarps (4-) 5-10(-14), sculptured or smooth , sometimes partly membranous, mostly beaked , often with 1 or 2 apical awns , often minutely stellate puberulent, dehiscent or indehiscent. Seeds 1 per mericarp, smooth, glabrous except sometimes for minute hairs around hilum .

Between 100 to 150 species: Africa, Asia, Australia, North and South America, Pacific islands; ca. 2/3 of the species American; 14 species (six endemic) in China.

Many species of this genus are used as fiber sources. Some species are widespread ruderals with sporadic distributions. Material with fully mature fruits is needed for reliable determinations. Studies of African material have demonstrated that there are superficially similar species that differ most obviously in details of mericarp morphology, and detailed studies have led to the recognition of more, rather than fewer, taxa. More information is needed on variation within populations, particularly in mericarp morphology, to assess the status of the awnless species of Sida, as there are indications that awned and awnless mericarps can occur on the same plant, thereby suggesting a possible reduction in species numbers.[2]
