Abstract

Primulina aureipurpurea, endemic to the limestone area in Dahua County, Guangxi Zhuang Autonomous Region, China, is described and illustrated here. This species is distinguished from P. albicalyx by leaves sessile or with indistinct short petioles (vs. distinctly petiolate, 21–42 mm long in P. albicalyx, the following comparisons are in the same order) and blades oblanceolate, narrowly obovate to obovate (vs. ovate to broadly ovate); bracts smaller, lanceolate (3–4× ca. 1 mm) (vs. ovate to narrowly ovate, 18–25 × 9–14 mm); filaments glabrous and ca. 1.5 mm long (vs. sparely glandular pubescent and 2–2.5 mm long) and pistil sparsely eglandular-puberulent (vs. densely glandular-pubescent). According to the IUCN Red List criteria, the currently known population of this species is provisionally assessed as “Vulnerable, VU D2.”
