Lysimachia kwangtungensis (Hand.-Mazz.) C. M. Hu

In its habit and foliage, this species shows some affinity to Lysimachia hemsleyi Franchet and L. fistulosa Handel-Mazzetti. It is readily distinguished from these species by its red or dark purple glandular punctate corolla lobes.

Leaves opposite; petiole 4--10 mm, narrowly margined, ± clasping; leaf blade ovate-lanceolate to lanceolate, 1.5--7 X 1--2.2 cm, sparsely setulose on both surfaces, rarely glabrescent, translucent glandular punctate throughout and densely so at margin, base narrowly cuneate, apex acuminate; lateral veins 3 pairs, slender, oblique. Pedicel ca. 5 mm. Flowers 4--10, congested at stem apex; bracts ovate, ciliate. Calyx parted nearly to base; lobes lanceolate, 5--6 X 0.6--1 mm, pubescent outside. Corolla yellow; tube ca. 1 mm; lobes glandular red to dark purple, oblong-elliptic, 8--9 X 5--5.5 mm, apex obtuse. Filaments connate into a ca. 2 mm high tube, free parts 2--3 mm; anthers oblong, ca. 1.2 mm. Ovary pilose on upper half; style 5--6 mm. Capsule brown, subglobose, 3.5--4 mm in diam. Fl. May-Jun.
