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：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）在親緣關系上相近，與后者的區別在于本種的植株均較低，高9～15 cm，萼距較短，長9～11 mm，雌蕊群由4 枚心皮構成。在葉城翠雀花，植株高45～50 cm，萼距長11～14 mm，雌蕊群由5 枚心皮構成［1，3］。

Delphinium gongliuense W.T.Wang & Z.Z.Yang，sp.nov.Fig.2.

（Sect.Elatopsis Huth subsect.Elata W.T.Wang）

Ob folia 3-partita，sepalum superum calcari leviter longius，staminodia nigra，carpella 3 species nova haec est affinis D.actoensi W.T.Wang，a quo foliorum laminis utrinque hirtellis，racemis compositis，bracteolis linearibus 8.0-9.5 mm longis apice longe apiculatis recedit.In D.actoensi，foliorum laminae supra glabrae，racemi simplices，et bracteolae subulatae，4 mm longae，enerves，apice haud apiculatae sunt.

Perennial herbs 43-53 cm tall. Stems simple，with petioles spreading-hirtellous，4-5-leaved. Basal leaf 1，long petiolate；blades papery，petagonal，ca.7.0 cm×10.5 cm，at base shallowly cordate，3-parted slightly exceeding the middle of blade，on both surfaces appressed-hirtellous，central primary lobe trapezoidal-rhombic，ca. 3.5 cm broad，3-lobed，with secondary lobes 3-lobulate or 2-denticulate，lateral primary lobes larger，obliquely flabellate，unequally 2-lobed，upper secondary lobes 3-lobulate and lower secondary lobes 2-lobulate；petioles ca.25 cm long. Cauline leaves similar to basal one，but smaller，and upper ones shortly petiolate. 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. Flower：Sepals blue-pruple，abaxially appressed-hirtellous，adaxially with a few hairs；upper sepal ovate，14-16 mm×7 mm；lateral sepals obliquely broad-obovate，ca. 14 mm×9 mm；lower sepals obliquely broad-oblanceolate，ca. 17 mm×7 mm. 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：02331415；isoteype，PE.）。

本種的葉3 深裂，上萼片比距稍長，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）在親緣關系上相近，與后者的區別在于本種的葉片兩面均被微硬毛，花序為復總狀花序，小苞片條形，長8.0～9.5 mm，頂端有長尖頭。在阿克陶翠雀花，葉片上面無毛，花序為簡單總狀花序，小苞片鉆形，長4 mm，無尖頭［2］。
