Tamarix: tree or shrub, 3-6 (-8) meters high; old branches are upright, dark brown red, bright, young branches are dense and weak, often open and drooping, reddish purple or dark purple red, shiny; dense young branches Slender and overhanging. The leaves are bright green, and the leaves on the green vegetative branches that grow from the raw woody growth branches are oblong-lanceolate or long ovoid, 1.5-1.8 mm long, slightly spread, pointed at the apex, and keel-shaped bulge on the back of the base, often present Membrane; the leaf diamond-shaped or ovate-lanceolate on the upper green vegetative branch, semi-adaptive, apex acuminate and inwardly curved, base narrowed, 1-3 mm long, with keel-like protrusions on the back. It blooms two or three times a year. It blooms every spring. Racemes grow laterally on woody twigs, 3-6 cm long and 5-7 mm wide. The flowers are large and few, sparse and slender, and the branchlets fall down; have short general pedicels. , Or nearly sessile, with a few bracts or no stalks; bracts are linear-oblong, or oblong, acuminate, as long as or slightly longer than the pedicels; pedicels are slender, shorter than the calyx; flowers are 5 out; Sepals 5, long and narrow ovate, with short pointed head, slightly entire, 2 outside, ridged abaxially, 0.75-1.25 mm long, slightly shorter than petals; petals 5, pink, usually ovate-elliptic or elliptic-obovate , Sparsely obovate, about 2 mm long, slightly longer than the calyx, persistent in fruit; disc 5-lobed, lobes rounded or slightly concave at the apex, purplish red, fleshy; stamens 5, longer or slightly longer than petals, filaments inserted on disc lobes The ovary is conical and bottle-shaped, and the style is 3, club-shaped, about half the length of the ovary. Capsules conical. Flowering in summer and autumn; racemes are 35 cm long, thinner than those born in spring, born at the top of young shoots of the year, forming a terminal large panicle, loose and usually recurved; flowers 5 out, slightly smaller than spring ones, densely growing ; Bracts are green, herbaceous, narrower than those of spring flowers, longer than pedicels, linear to linear cones or narrow triangles, acuminate, narrowing downwards, ridges on the back of the base, entire; calyx is triangular Oval; the petals are pink, straight and slightly oblique, much longer than the calyx; the disc is 5 lobed, or each lobe is 2 divided into 10 lobes; the stamen is 5, the length is equal to or twice the petal, the anther is obtuse, The filaments are inserted between the main lobes of the flower plate, and emerge from the edge and slightly below; the style is stick-like, and its length is equal to 2/5-3/4 of the ovary. Flowering from April to September.
