C91587ECFF91FFE3FF28FF14FBB1F8E8.taxon	distribution	Distribution: — China. Only known from a small population at the type locality on Kongtong Mountain (22 ° 11 ′ N, 111 ° 44 ′ E) ca. 16 km west of Yangchun City in southwestern Guangdong Province (Figure 4). Habitat and flowering time: — Paraboea tetrabracteata grows in crevices of sun-facing cliffs of a limestone hill, at an elevation between 38 and 80 m. The forest where P. tetrabracteata occurs is subtropical evergreen broad-leaved forest. Flowering time is in June.	en	Wen, Fang, Hong, Xin, Chen, Ling-Yun, Zhou, Shou-Biao, Wei, Yi-Gang (2013): A new species of Paraboea (Gesneriaceae) from a karst limestone hill in southwestern Guangdong, China.

C91587ECFF91FFE3FF28FF14FBB1F8E8.taxon	etymology	Etymology: ― The epithet refers to its four bracts. Vernacular name: ― SiBao Zhumaojutai (Chinese). Notes: ― Paraboea tetrabracteata is morphologically similar to P. dictyoneura (Hance 1883: 169) B. L. Burtt (in Burtt 1984) and P. rufescens (Franchet 1884: 449) B. L. Burtt (in Burtt 1984) in several characters (Figure 3), but can be easily distinguished by the characters provided in Table 1.	en	Wen, Fang, Hong, Xin, Chen, Ling-Yun, Zhou, Shou-Biao, Wei, Yi-Gang (2013): A new species of Paraboea (Gesneriaceae) from a karst limestone hill in southwestern Guangdong, China.
