植物体高5-15厘米，茎基褐色至暗褐色，有密绒毛。根粗壮，直径达3厘米。当年枝多条，发自茎基，黄绿色，直立，不分枝，通常具5-8节间；节间近圆柱状，直径2-3毫米，平滑，有时具伤疤状斑痕。叶鳞片状，圆柱形，长1-2毫米，边缘膜质，先端钝，无刺状尖。花单生叶腋，小苞片卵状矩圆形，先端稍锐；花被片外轮3片宽椭圆形，内轮2片较狭，果时通常仅外轮3片具翅；翅膜质，肾形或近圆形，粉红色（干后淡黄色）；花盘裂片条形，顶端蓖齿状；子房平滑，柱头通常外弯。胞果暗红色或澄黄色，长2-2.5毫米。花果期8-10月。
产新疆北部。生于戈壁、盐碱土荒漠、干山坡等处。分布于欧洲、中亚、苏联西西伯利亚。

Anabasis cretacea Pallas
白垩假木贼 bai e jia mu zei
Anabasis tianschanica Botschantzev.
Herbs perennial, 5-15 cm tall. Root stout, to 3 cm in diam. Caudex brown to dark brown, densely tomentose; annual branches numerous, borne on caudex, erect, simple, yellow-green, usually with 5-8 internodes; internodes subterete, 2-3 mm in diam., smooth, sometimes with leaf scars. Leaves scale-like, terete, 1-2 mm, margin membranous, apex obtuse, awnless. Flowers solitary in leaf axils; bractlets ovate-oblong, apex slightly obtuse. Outer 3 perianth segments broadly elliptic, usually only these segments winged in fruit; inner 2 segments narrower; wing pink, reniform or suborbicular, membranous. Disk lobes linear, apex pectinate. Ovary smooth; stigmas usually recurved. Utricle dark red or orange-yellow, 2-2.5 mm. Fl. and fr. Aug-Oct.
Gobi desert, saline-alkaline deserts, arid slopes. N Xinjiang [Russia (SE European part, W Siberia); C Asia].
The general distribution of this species needs clarification, as well as its occurrence in China. Grubov (Rast. Tsentral. Azii 2: 107. 1966) considered C Asian records to belong to A. truncata.
