03A487AD947AFFFDF49DFF68FEC6965E.taxon	distribution	Distribution and ecology: — Pinellia calcicola is a rare herbaceous species currently known only from a few localities in the Lijiang River [NJū] region in the vicinity of the city of Guilin, where it shows an obvious association with karst landforms. Field observations indicate this species is a karst obligate, growing exclusively in semi-shaded, persistently moist limestone crevices on undisturbed hill summits dominated by sclerophyllous and broad-leaved shrubs at elevations of 150 – 230 m.
