F6CAD151C84054CF8014305006360C57.taxon	distribution	Distribution and habitat. Tilia saxatilis has only been collected from five localities restricted to central Guangxi of China. It grows sporadically in forests on limestone slopes, rare on peaks, at an elevation of 700 – 950 m. The type localities are typical limestone karst landform and belong to the southern subtropical monsoon climate areas, the average annual temperature being 18 – 21 ° C; the annual sunshine duration is 1220 – 1590 hours and the annual accumulated temperature is about 6300 ° C; the annual average relative humidity is 74 – 80 %; the average annual rainfall is 1250 – 1680 mm and the evaporation is 1210 – 1650 mm.	en	Lu, Zhao-Cen, Chang, Shi-Li, Mo, Ming-Lin, Wu, You-Dong, Xu, Wei-Bin (2025): Tilia saxatilis (Malvaceae), a new species from limestone areas of Guangxi, China.
