Abstract

Primulinaaureipurpurea, 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."

Primulinaaureipurpurea(苦苣苔科),广西一新种。
报春花(Primulinaaureipurpurea)是中国广西壮族自治区大化县石灰岩地区特有的一种植物。本种与白萼蓼的区别在于叶片无梗或有不明显的短叶柄(与明显叶柄相比,白萼蓼长21-42毫米,以下比较在同一顺序)和叶片倒披针形,窄倒卵形到倒卵形(与卵形到宽卵形相比);苞片较小,披针形(3-4×约1毫米)(相对卵形到窄卵形,18-25 × 9-14毫米);花丝无毛和约1.5毫米长(相对于疏生腺短柔毛和2-2.5毫米长)和雌蕊疏生腺微柔毛(相对于密生腺短柔毛)。根据世界自然保护联盟的红色名录标准,目前已知的这种物种的数量暂时被评估为“易危,VU D2”。
