Flowers usually in racemes or panicles, rarely solitary, usually hermaphroditic , regular. Calyx 4- or 5-fid, persistent . Petals 4 or 5, free , deciduous after anthesis or sometimes persistent. Disk inferior, usually thick, nectarylike. Stamens 4, 5, or more numerous , usually free, inserted on disk, rarely united into fascicle at base , or united up to half length into a tube . Anthers 2-thecate, longitudinally dehiscent . Pistil 1, consisting of 2-5 carpels; ovary superior, 1-loculed; placentation parietal , rarely septate , or basal; ovules numerous, rarely few; styles short, usually 2-5, free, sometimes united. Capsule conic, abaxially dehiscent. Seeds numerous, hairy throughout or awned at apex; awns puberulous from base or from middle ; endosperm present or absent; embryo orthotropous .

Three genera and ca. 110 species: steppe and desert regions of the Old World; three genera and 32 species (12 endemic) in China.

Myrtama has been placed alternatively in Myricaria, Tamarix, or treated as a separate genus (see Gaskin et al. , Ann. Missouri Bot. Gard. 91: 402-410. 2004; Zhang et al., Acta Bot. Boreal.-Occid. Sin. 20: 421-431. 2000) .[1]

Genus Tamarix

Shrubs or trees , much branched. Young branches usually glabrous ; two types of branches present: ligneous growing branches, not deciduous in winter vs. green vegetative branchlets , deciduous in winter. Leaves alternate, sessile, amplexicaul or vaginate , small, scale-like, glabrous, rarely hairy , mostly with salt-secreting glands . Flowers in racemes or panicles, blooming in spring ; racemes lateral on growing branches of previous or current year and clustered in terminal panicles, or two types of flowering habits present in some species. Flowers bisexual , rarely unisexual , 4- or 5(or 6) -merous, usually pedicellate ; bract 1. Calyx herbaceous or fleshy , 4- or 5-fid; lobes entire or faintly denticulate . Petals as many as calyx lobes, deciduous or persistent after anthesis . Disk variously shaped, mostly 4- or 5-lobed; lobes entire, or apex retuse or even deeply divided . Stamens 4 or 5, opposite to calyx lobes, or numerous , outer series opposite to calyx lobes; filaments often free , inserted between lobes of disk or at apices of lobes; anthers cordate, versatile, 2-thecate, longitudinally dehiscent . Pistil consisting of 3 or 4 carpels; ovary mostly conic, many seeded; placentation basal-parietal; styles 3 or 4; stigmas capitate, short. Capsule conic, abaxially 3-septicidal. Seeds numerous, minute; apical awns villous .

About 90 species: Africa, Asia, Europe; 18 species (seven endemic) in China.[2]
