Aspidistra revoluta (Asparagaceae) is described and illustrated as a new species from limestone areas in southern Chongqing Municipality, China. The new species can be distinguished from the other Aspidistra species by its unique umbrella-like pistil with large revolute stigma lobes that bent downwards and touch the base of the perigone. A detailed morphological comparison among A. revoluta, A. nanchuanensis and A. carnosa is provided. The pollen grains of A. revoluta are subspherical and inaperturate, with verrucous exine. The chromosome number is 2n = 38, and the karyotype is formulated as 2n = 22m + 6sm + 10st. The average length of chromosome complement is 4.50 μm, and the karyotype asymmetry indexes A1 and A2 are respectively 0.37±0.03 and 0.49±0.01. © 2016 Magnolia Press.

Gastrochilus brevifimbriatus S. R. Yi is described and illustrated as a new species of Gastrochilus D. Don (Orchidaceae, Aeridinae) from Jinfo Mountain, Chongqing Province, China. This new species is related to G. acinacifolius Z. H. Tsi, with both species characterized by the falcate, lanceolate leaves, the inflorescences opposite to the leaves, the yellow sepals and petals with purple spots, the similar petals and sepals, and the white lip. Gastrochilus brevifimbriatus differs by its longer stems (10-30 cm) and by the subflabellate epichile that is broader than the hypochile and has short fimbriae on the margins. © Missouri Botanical Garden 2010.
