Aquilegia rockii Munz

Stems 40--80 cm tall, basally sparsely pubescent, apically densely glandular pubescent and often branched. Basal leaves few, 2-ternate; petiole 8--22 cm; leaf blade abaxially basally pubescent, adaxially subglabrous; lateral leaflets obliquely ovate, unequally 2-lobed to middle; central leaflet cuneate-obovate, 1.5--4.5 × 1.2--4.5 cm, 3-lobed. Stem leaves 2 or 3 or more. Inflorescences cymose, 1--3-flowered; bracts 3-parted. Flowers pendulous or in a ± 90° angle, 3.5--4 cm in diam. Pedicel to 12 cm, densely glandular pubescent. Sepals purple or blue, narrowly ovate, 2--3 × 0.7--0.9 cm. Petals purple or blue, suberect, oblong, 1--1.5 cm, apex rounded-truncate; spur 1.6--2 cm, pubescent, straight or apically slightly incurved. Stamens shorter than petals; anthers black, oblong, ca. 1 mm. Staminodes lanceolate, 6--7 mm. Pistils 5, erect, densely glandular hairy. Follicles 1.5--2.1 cm; persistent styles 5--7 mm. Seeds ca. 2 mm. Fl. Jun--Aug, fr. Jul--Sep.

SW Sichuan, SE Xizang, NE Yunnan.

* Mixed forests, alongside roads; 2500--3500 m.

Flowering from June to August; fruiting from July to September.

Aquilegia rockii is close relative of Aquilegia moorcroftiana, but differs from the latter in its 2-3 cm long (vs. 1.4-2.1 cm long) sepals, stamens shorter than petals (vs. stamens slightly longer than or nearly as long as petals), black (vs. yellow) anthers.

Aquilegia rockii is occurring in SW Sichuan, SE Xizang, NE Yunnan of China.

Aquilegia rockii is a species of flowering plant in the buttercup family with a native range comprising the WGSRPD floristic regions of South-Central China and Tibet, where it grows in forests. Plants grow 40-80cm tall, and produce flowers with purple or blue petals with spurs, which are either long or short. Longer spurs comprise a greater number of cells than shorter spurs; whether spurs are longer or shorter is determined through regulation of cell division rather than by plant growth substances.

The chloroplast genome of Aquilegia rockii has been fully sequenced: it has a total length of 162,123 base pairs, and contains 117 unique genes. Phylogenies based on chloroplast genome sequences place Aquilegia rockii in a clade with A. viridiflora and A. ecalcarata.

Aquilegia rockii là một loài thực vật có hoa trong họ Mao lương. Loài này được Munz mô tả khoa học đầu tiên năm 1946.
