References  
Comments The FoC description states that perianth lobes are "1 - 1.2 cm wide"; this must be the width at the base of the lobes.  The FoC states "style articulate"; the drawings (and photograph in Li Guangzhao) show the stigma to be sessile, which while not excluding articulation makes it unlikely.

One of the most spectacular Aspidistra in flower.
