Lysimachia cavicola (Primulaceae), a new species from Guangxi, China
Lysimachia cavicola (Subgen. Idiophyton, Primulaceae), a new species from Guangxi, China, is here described and illustrated based on morphological data. Although it shares similarities with L. microcarpa, L. fooningensis, and L. capillipes, there are distinguishing characteristics that set it apart. These include erect stems either solitary or in clusters of 1 to 2, herbaceous, terete, and densely glandular hairy. The leaves are either ovate or elliptical lanceolate, with inconspicuously reticulate veins. The petiole measures 2–4 mm in length covered with minute glandular hairy. The corolla is deeply parted, measuring 6–8 mm in length, with narrowly elliptic or narrowly oblong lobes that are 1–2 mm wide. The capsule is globose, measuring 2–3 × 2–3 mm, and possesses a chalky, brittle texture, which splits into 5-valved segments. The calyx of the plant appears yellowish-white during fruiting. This newly discovered species is endemic to limestone areas in Fengshan County, Guangxi, China.
