Saxifraga dianxibeiensis J. T. Pan

This taxon may merely be a dwarf variant of Saxifraga diversifolia, much as was believed by Engler and Irmscher (loc. cit.).

Herbs perennial, densely cespitose, 12.5-18.5 cm tall. Stem proximally brown villous at leaf axils, distally dark brown glandular hairy. Basal leaves with petiole 1-2.6 cm, brown villous at margin; leaf blade cordate to ovate-cordate, 1.1-2 × 1-1.6 cm, brown pilose, base cordate, apex obtuse or acute. Proximal cauline leaves with petiole 2-16 mm, margin brown pilose; leaf blade cordate to ovate or narrowly so, 1.4-1.8 cm × 6.5-7 mm, base cordate to rounded, apex subobtuse or acute; distal cauline leaves sessile, lanceolate to oblong, 1.2-1.4 cm × 3-4.5 mm, both surfaces glabrous, base rounded to cuneate, margin brown pilose, apex subobtuse or acute. Flower solitary or cyme 2- or 3-flowered; pedicels 1.5-3 cm, dark brown glandular hairy. Sepals spreading to reflexed, ovate to broadly so, 3.3-4.8 × 2-3.2 mm, abaxially glabrous or sparsely glandular hairy, veins 5-9, not, partly, or fully confluent at apex, margin dark brown glandular ciliate, apex obtuse. Petals yellow, elliptic or broadly so to broadly ovate, 6-6.4 × 4.2-5 mm, 8- or 9-callose or obscurely so, 4-12-veined, base contracted into a claw 0.5-1 mm, apex obtuse. Stamens 3-5 mm.
