Later, this species was treated as a synonym of  A. laguroides by Xu and Podlech (2010). However, based on our extensive morphological studies,  A. gobi-altaicus can be distinguished from  A. laguroides by its inflorescence being oblong-cylindrical (vs. globose or ovate), leaflets that are broadly elliptical or oblong-obovate, more rarely sub-oval (vs. leaflets oblong, narrowly elliptical, or lanceolate), calyx teeth 4–6 mm long (vs. calyx teeth 3–4) (Table 2). In addition, the phylogenetic tree supported that  A. gobi-altaicus was different from  A. laguroides, which was more similar to  A. oyunicus and  A. lupulinus (Fig. 1).</p><p>Type.</p><p>Mongolia.

According to the description of  A. tamiricus, some morphological characteristics, such as racemes, leaflets, stipules, and flowers, including calyx, standard, keel, and wings, are slightly smaller than  A. laguroides (Biazrov et al. 1989) . However, our studied samples of  A. tamiricus, collected from the type location in Arkhangai Province, clustered with  A. laguroides based on our phylogenetic tree (Fig. 1). Therefore, we treated  A. tamiricus as an additional synonym of  A. laguroides in this study.</p><p>Description.</p><p>Plants perennial 8–15 (– 20) cm tall, acaulescent or nearly so, in vegetative parts covered with medifixed, appressed white hairs. Stems, if present, up to 1 cm, angular-sulcate, densely hairy. Stipules 6–8 (– 10) mm, narrowly triangular-acuminate, adnate to the petiole for c. 3–4 mm, otherwise free from each other, covered with spreading or ascending hairs. Leaves 3–14 (– 18) cm; petiole 1.5–5 (– 8) cm, like the rachis rather densely to densely, more rarely loosely hairy. Leaflets in 3–5 (– 8) pairs, in the basal leaves often only in 1–2 pairs, narrowly elliptic to more rarely elliptic, 8–25 (– 40) × 3–6 mm, acute, on both sides rather densely appressed hairy. Peduncles 2–12 cm, rather densely covered with symmetrically to asymmetrically bifurcate, appressed to subappressed white hairs, toward the raceme sometimes also with some black hairs mixed in. Racemes ovoid, 2–4 (– 6) cm long, densely many-flowered. Bracts linear-acute, 4–8 mm, covered with asymmetrically bifurcate, at the margins with basifixed white hairs. Calyx at anthesis tubular, soon becoming ovoid-inflated, 11–14 mm, loosely to rather densely covered with asymmetrically bifurcate to basifixed, tangled, spreading white hairs 1–2 mm, at outer side of the teeth and sometimes at the nerves of the tube also with black hairs; teeth subulate, 3–4 mm.

Choi sp. nov.</p><p>Fig. 7</p><p>Diagnosis.</p><p>Astragalus uvsicus is morphologically similar to  A. beitashanensis W. Chai &amp; P. Yan (Zhai and Yan 2010) and  A. laguroides, but can be distinguished by its leaflet 2–5 pairs, narrowly elliptic, acute 8–11 (– 14) × 3–5 mm ( A. beitashanensis, vs. 3–5 pairs, elliptic to suborbicular, obtuse, 4–9 × 3–6 mm; vs.  A. laguroides, 3–5 pairs, narrowly elliptic, acute 8–25 × 3–6 mm) Legumes linear, 5–6 × 2–3 mm, with a beak c. 1 mm, bilocular, loosely covered with spreading, straight hairs ( A. beitashanensis, legumes oblong, c. 8 mm, unilocular, very densely covered with spreading, basifixed hairs;  A. laguroides, legumes oblong, (6) 7–8 × 2–3 mm long, with a hooked beak c. 1 mm, unilocular; covered with subappressed to spreading hairs). At the section level, the Uvsicus section is differentiated by its plants covered with medifixed hairs (vs. covered with semi-appressed pilose in Mixiotricha), peduncle not longer than leaves, raceme many-flowered (vs. peduncle very short, raceme few-flowered in Trachycercis and Mixiotricha), legumes enclosed in the calyx (vs. calyx ruptured by legumes in  Macrotrichoides), and bilocular (vs. unilocular in  Laguropsis) (Table 3). The general habits of selected sections within the subgenus  Cercidothrix are shown in Fig. 8.</p><p>Type.</p><p>Mongolia.

Munkhtulga [Isotype UBU 0027685!]  .</p><p>Description.</p><p>Plants perennial, 5-12 cm tall, acaulescens or nearly so, covered with medifixed hairs. Rootstock with a pluricipital root-crown. Stipules narrowly triangular-acuminate, 5-7 mm, shortly adnate to the petiole, otherwise free from each other, covered with strongly asymmetrically bifurcate, subappressed white hairs up to 2 mm. Leaves 3-8 (12) cm; petiole 2-3 cm, like the rachis covered with medifixed, appressed hairs. Leaflets in 2-5 pairs, narrowly elliptic, 8-12 × 3-5 mm, apex acute, rather densely covered with medifixed, appressed hairs c. 1 mm. Peduncles 2-6 cm, with medifixed, appressed hairs. Racemes globose or ovate 3-4 cm long. Bracts scarious, 2-3 mm, narrowly triangular, white and few black hairy. Calyx at beginning of anthesis tubular, later on ovoid-inflated, 11-14 mm, with distinct, elevated longitudinal nerves, loosely covered with subbasifixed, spreading white and black hairs 1-2 mm; teeth subulate, 2-3 mm. Petals violet. Standard 15-18 mm; blade 3-4 mm wide, obovate, slightly constricted in the middle, emarginate, at the base gradually narrowed into the rather long claw. Wings 13-15 mm; blades narrowly oblong, obtuse, 5.5-6.5 × 1.1-2 mm; auricle c. 1 mm; claw 7.5-8.5 mm. Keel 12-14 mm; blades 4-5 × 3 mm. Ovary sessile. Legumes enclosed in the calyx, linear, c. 5-6 × 2-3 mm, with a beak c. 1 mm, bilocular, loosely covered with spreading, straight white hairs c. 1 mm, smaller black hairs amount greater than the apex.</p><p>Distribution.</p><p>Endemic to Mongolia.
