Distribution China (C Guangxi)

Description Rhizome: creeping subterete, diameter 5 - 7 mm.
Leaves: solitary to ca. 25 cm; cataphylls undescribed; petiole 6 - 7 cm, rather slender; lamina ovate to elliptic, 13 - 17 cm long x 5 - 6 cm wide.

Scape: 3 - 5 mm long with 5 - 6 bracts; flowers solitary.

Perianth [Perigone]: campanulate, pale yellow adaxially, speckled purple-red abaxially; tube rather thick-walled, ca. 1 cm long x 1.8 cm diameter; lobes 6 (-8), suberect, ovate-lanceolate, (1.7 -) 2 - 2.5 cm long x ca. 5 mm wide, with a short basal emarginate lobe projecting into the mouth of the perianth tube.

Stamens: 6, inserted at base of perianth tube, subsessile; anthers oblong, ca. 2 mm.

Pistil: bowl-shaped [?]; ca. 7 mm long; style ca. 5 mm long, thickened, 12-ribbed; stigma peltate, large, 1 - 1.2 cm in diameter, adaxially sculptured, comprising 4 lobes each lobe with 2 long marginal and one short central radial projections giving a 12-lobed margin, convex at centre with 4 vertical projections, appressed to the top of the perianth tube so as to almost close off the entrance, [the abaxial surface of the stigma is unclear, see notes]; ovary undescribed.

slightly 12-lobed at margin.

Fruit: undescribed.

Phenology: flowers March - April.

Comments It is not clear to me whether this sp. is normally 3-merous or 4-merous. The description in FoC is unusual in referring to the style as well as the stigma. It is possible that the FoC is treating the abaxial surface of the "stigma" as the style and the adaxial surface as the stigma.
