Family Tamaricaceae

Shrubs , subshrubs , or trees . Leaves small, mostly scale-like, alternate, estipulate, usually sessile, mostly with salt-secreting glands . 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]

Physical Description

Species Tamarix aphylla

Trees or large shrubs . Young branches smooth . Leaves sessile, vaginate , ca. 2 mm, base amplexicaul , apex acute. Racemes 3-6 cm × 4-5 mm; when flowering in spring , racemes solitary; flowers blooming more commonly in summer, then racemes on new branches; flowers subsessile ; bracts triangular or broadly triangular, exceeding pedicels, base slightly amplexicaul, apex acuminate. Pedicels much shorter than calyx. Calyx 5-fid, ca. 1.5 mm, margin entire, apex obtuse ; outer 2 lobes slightly smaller, broadly ovate or broadly elliptic , abaxially slightly carinate ; inner 3 larger, broadly elliptic or suborbicular . Petals 5, elliptic, oblong , or ovate-elliptic, 2-2.3 mm, deciduous, sometimes 1 or 2 persistent in fruit. Disk 5-lobed; lobes emarginate at apex or deeply divided into 10 lobules . Stamens 5; filaments inserted between disk lobes. Fl. Sep-Oct and rarely in spring. 2n = 24*. [source]
