Trees or shrubs , rarely herbs or liana; young growth usually stellately hairy ; bark mucilaginous and rich in fibers. Leaves alternate; stipules usually present caducous ; leaf blade simple , rarely palmately compound , entire, serrate, or parted . Inflorescence axillary or rarely terminal , paniculate , corymbose , racemose, or cymose , rarely solitary. Flowers unisexual , bisexual or polygamous. Sepals (3-) 5, ± connate , rarely free , valvate . Petals 5 or lacking, free or adnate to base of androecium, convolutely imbricate. Androgynophore usually present; filaments usually connate into a single tube ; staminodes 5, tonguelike or filiform , opposite to sepals, sometimes lacking; anthers 2-celled, longitudinally dehiscent . Pistil consisting of 2-5(or 10-12) ± connate carpels, or a single carpel; ovary superior, 2-5(or 10-12) -loculed; ovules 2 or more per locule; style 1 or as many as carpels. Fruit usually a capsule or follicle, dehiscent or indehiscent, very rarely a berry or nut. Seeds with abundant endosperm or endosperm lacking; embryo straight or curved .

About 68 genera and ca. 1100 species: tropics and subtropics of both hemispheres, a few in temperate regions ; 19 genera (two introduced ) and 90 species (39 endemic, three introduced) in China.

The Chinese genera fit into four distinct clades which can be treated as subfamilies of an enlarged Malvaceae or as distinct families. These are Sterculioideae/Sterculiaceae s.s. (genera 1-4), Helicteroideae/Helicteraceae (genera 5 and 6), Byttnerioideae/Byttneriaceae (genera 7-13), and Dombeyoideae/Pentapetaceae (genera 14-19) .[1]

Genus Lophanthus

Herbs perennial . Stem leaves short petiolate to sessile, dentate or incised-toothed. Cymes axillary ; bracts small, linear-lanceolate to linear , rarely lanceolate. Calyx tubular to tubular-campanulate, straight or ± incurved , apex regular or oblique ; teeth 5, subequal , ± 2-lipped [or not], (12-) 15-veined, pilose annulate inside. Corolla straight or incurved; tube exserted, gradually dilated upward, twisted; limb 2-lipped, twisted at 90-180° so that position of lips is ± reversed ; upper lip (true lower) 3-lobed, middle lobe largest; lower lip (true upper) 2-lobed. Stamens 4, exserted or included ; anther cells parallel or almost not divergent. Style exserted, rarely included, apex equally or subequally 2-cleft. Nutlets brown, oblong-ovoid, slightly flattened, smooth .

Eighteen species: Kazakhstan, Kyrgyzstan, Mongolia, Russia, SW Asia; four species in China.[2]
