Abstract:Aspidistra papillata G. Z. Li and A. huanjiangensis G. Z. Li & Y. G. Wei, two new species of Liliaceae from Guangxi, are described and illustrated. A. papillata is closely related to A. tonkinensis (Gagnep.) F. T. Wang & K. Y. Lang in having solitary flowers, campanulate perianth with the three outer lobes covering the three inner ones on both sides at base, peltate stigma with the margin 3_lobed and the top radially 3_sulcate, but different by the larger plant, thicker petiole 2.5-3.5 cm in diameter, elliptic or oblong_elliptic leaves, broadly campanulate perianth purplish outside, purple and 7_sulcate inside, grayish_white stigma densely papillate. A. huanjiangensis is similar to A. cavicola D. Fang & K. C. Yen in the plant smaller, and leaves smaller less than 14 cm long and 4.5 cm wide, but different by having leaves entire, stigma truncate on top, deeply trifurcate_lobed with the lobes bifurcate.
