DF5687BBB060FF9917BC127A2E36DDD1.taxon	diagnosis	Diagnosis: — Lysimachia daqiaoensis is similar to L. rupestris F. H. Chen & C. M. Hu (1979: 40) in having rosette leaves and being glabrous all the plants, but the former has no stolons, racemose inflorescences and solitary flowers, longer filaments (ca. 5 mm), and shorter (ca. 0.8 mm) and dorsifixed anthers opening by lateral slits, while the latter has obvious stolons, solitary flowers only, shorter filaments (ca. 1 mm), and longer (4 – 5 mm) and basifixed anthers opening by apical pores. Herbaceous perennial, glabrous. Rhizome subterete, less than 1 cm, 5 – 8 mm in diameter, branched at the apex of the rhizome, densely white or brown crystals, no stolons. Leaves thickly papery to thinly leathery, spirally arranged, congested at the apex of the rhizome, forming a rosette, elliptic-oblanceolate, long oblanceolate, 2.5 – 12 × 1.2 – 3.5 cm, tapering towards the base, margin entire and revolute narrowly, apex acute to obtuse; petiole 0.6 – 2.5 cm long, narrowly winged, white or brown crystals on both sides; veins 2 or 4 pairs, inconspicuous on two sides; veinlets invisible adaxially when drying. Racemose inflorescences, ca. 8 - flowered, axillary. Peduncles 1.6 – 2.5 cm long, densely white or brown crystals. Bract Linear, 3 – 5 mm, borne from the base of pedicel. And some flowers solitary. Calyx lobes triangular, ca. 4 × 1.2 mm, separate to near the base, apex acuminate, densely white or brown crystals, veins inconspicuous. Corolla yellow, separate near to base, lobes imbricate, lanceolate to elliptic, 7 – 9 mm × ca. 3 mm, apex obtuse to emarginate, glabrous, red stripe at base. Stamens 5, filaments ca. 5 mm long, connate basally into a tube; anthers ca. 0.8 mm long, ca. 0.6 mm in diameter, dorsifixed, opening by lateral slits. Ovary globose, glabrous, ca. 1 mm in diameter; style ca. 6 mm long, glabrous. Capsule subglobose, ca. 3 mm in diameter. Calyx and style persistent in fruit. Fruit stalk curve toward wet rock when ripening. Phenology: — The flowering of Lysimachia daqiaoensis is from April to May; and the fruiting from July to September.	en	Huang, Rui-Zhou, Liao, Miao, Han, Wei, Yang, Yuan-Zhi, Zhou, Ming-Yi, Feng, Han-Hua, Tang, Guang-Da (2020): Lysimachia daqiaoensis (Primulaceae), a new cave species from Guangdong, China.
