Basal leaves ca. 3,long petiolate;blades subcoriaceous,reniform,1.5-2.8 cm×2.8-4.0 cm,at base cordate,3-parted,central lobe cuneate-obovate or rhombicobovate,on apex or above incised-dentate,lateral lobes larger,obliquely flabellate,unequally 2-lobulate to 2-cleft,on apex incised-dentate;surfaces adaxially and abaxially covered with very short appressed hairs 0.1-0.5 mm long,sometimes mixed with sparse short glandular hairs;petioles 4-8 cm long,sparsely puberulous. Cauline leaves similar to basal ones,but upper ones smaller. Corymbs terminal and axillary,2-4-flowered;basal bract similar to cauline leaves but small,or undivided,with narrowly elliptic blade,and upper bracts sessile,narrowspatulate or linear,1-2 cm long,glabrous;pedicels 1.0-6.5 cm long,densely white-pubescent and yellow-glandular-pubescent,above 2-bracteolate;bracteoles linear,4-12 mm×1-1.2 mm,glabrous. Flower:Sepals blue-purple,purple or purplish,on both sides with sparse hairs and on out side also mixed with a few glandular hairs;upper sepal broadly ovate,16-22 mm×17-20 mm,spur narrow-conical,9-11 mm long,at base 6.5-7.0 mm in diam.;lateral sepals orbicular-ovate,18×11-18 mm;and lower sepals broadly obovate,12-20 mm×15-16 mm. Petals 2,black,apex 2-lobulate and pilose. Staminodes 2,black;limbs suboblong or narrow-ovate,ca. 8 mm×3 mm,2-lobed,adaxially below the middle densely yellowish-barbate;claws ca. 7 mm long,abaxially obove puberulous. Stamens ca. 35;filaments ca. 8 mm long,1-blue-nerved,above narrow-linear,below linear-lanceolate,glabrous or above the middle on each side with 1 or 2 hairs;anthers oblong,1.0 mm×0.6 mm,glabrous. Carpels 4;ovaries green,linear,4.0-4.6×0.8 mm,densely pubescent;styles whitish,0.7-1.0 mm long,glabrous.

        新疆(Xinjiang):塔什庫(kù)爾干縣(Tashikurgan Xian),alt.4 400 m,多石礫草坡,花紫色,花梗被白色柔毛和黃色腺毛(on rocky grassy slope,fls. purple,pedicels covered with white hairs and yellow glandular hairs),2019-08-03,楊宗宗(Z.Z.Yang)7659(holotype,PE);同地,同一日(same locality and on same day),alt. 4 430 m,多石礫草坡,花藍(lán)紫色(on rocky grassy slope,fls. blue-purple),楊宗宗7661(PE);同地,同一日,alt.4 560 m,石礫山坡,花粉紫色(on rocky slope,fls.pink-purplish),楊宗宗7238(PE,條形碼號(hào):02331415)。

        本種的花序傘房狀,萼距比萼片短,花瓣和退化雄蕊均呈黑色,因此與也具上述特征的葉城翠雀花(Delphinium yechengense C.Y.Yang&B.Wang)在親緣關(guān)系上相近,與后者的區(qū)別在于本種的植株均較低,高9~15 cm,萼距較短,長(zhǎng)9~11 mm,雌蕊群由4 枚心皮構(gòu)成。在葉城翠雀花,植株高45~50 cm,萼距長(zhǎng)11~14 mm,雌蕊群由5 枚心皮構(gòu)成[1,3]。

Compound raceme terminal,ca. 9 cm long,terminal raceme 5-7 cm long,densely 14-flowered,lateral racemes 2-3,3-5 cm long,densely 4-6-flowered;lower bracts similar to upper cauline leaves,but smaller;rachis spreading-hirtelous; pedicels 0.6-1.6 cm long,densely spreading-hirtellous,near apex 2-bracteolate;bracteoles linear,8.0-9.5 mm×1.0-1.6 mm,hirtellous,at apex long apiculate.

Petals 2,black,glabrous.Staminodes 2,black;limbs trapezoidal,6.0-6.5 mm×2.0-3.5 mm,2-lobed,on margin above long ciliate,below lobes densely white-barbate;claws 6 mm long,at base minutely 1-appendiculate.Stamens ca.20,glabrous;filaments 5-6 mm long,below lanceolate-linear,1-nerved,above filiform;anthers darkblue,oblong,1 mm×0.35-0.50 mm. Carpels 3;ovaries oblong,3.0 mm×1.2 mm,puberulous;styles 1.6 mm long,glabrous.

        新疆(Xinjiang):鞏留縣,恰西(Gongliu Xian,Qiaxi),alt.2 680 m,山坡草地,花藍(lán)紫色(in grassy place on slope,fls.blue-purple),2.18-07-28,楊宗宗(Z. Z. Yang) 0817(holotype,PE,條 形 碼 號(hào):02331415;isoteype,PE.)。

        本種的葉3 深裂,上萼片比距稍長(zhǎng),退化雄蕊黑色,心皮3,因此與也具上述特征的阿克陶翠雀花(D.actoense W.T.Wang)在親緣關(guān)系上相近,與后者的區(qū)別在于本種的葉片兩面均被微硬毛,花序?yàn)閺?fù)總狀花序,小苞片條形,長(zhǎng)8.0~9.5 mm,頂端有長(zhǎng)尖頭。在阿克陶翠雀花,葉片上面無(wú)毛,花序?yàn)楹?jiǎn)單總狀花序,小苞片鉆形,長(zhǎng)4 mm,無(wú)尖頭[2]。
