Lysimachia taliensis Bonati

The corolla lobes in this species are typically obovate, making it distinctive. When the lobes are oblong and only 2 mm wide, this species is difficult to distinguish from Lysimachia delavayi Franchet.

Herbs perennial, glabrous, 35--80 cm tall. Stems erect, simple or branched in upper part; branches subverticillate. Leaves in whorls of 3 or 4, opposite on branches, subsessile, lanceolate to linear, 4--11 X 0.5--1(--2.3) cm, abaxially glaucous, with many scattered dark purple to black glandular dots or stripes, or sometimes obscure and slightly raised, adaxially dark green, base cuneate-attenuate, subauriculate-dilated. Racemes terminal, 4--7 cm, elongating to 25 cm in fruit; bracts linear, 3--6(--9) mm. Pedicel 5--7 mm, elongating to 1 cm in fruit. Calyx lobes linear-lanceolate, 4--5(--7) mm, dark purple wide glandular striate outside, hyaline margined, apex acute, costate. Corolla white or pink; tube 2--2.5 mm; lobes obovate to oblong-elliptic, 4--6(--8.5) X 2--4 mm, apex rounded; sinus between lobes obtuse. Stamens ca. as long as to slightly shorter than corolla lobes; filaments adnate to base of corolla lobes, free parts ca. 3 mm; anthers elliptic, dorsifixed, ca. 1 mm. Ovary glabrous; style 5--6 mm. Capsule subglobose, 4--5 mm in diam. Fl. Apr.
