Aspidistra longanensis

Accepted name Aspidistra longanensis Y. Wan. Acta Phytotax. Sin., 23(2): 151, fig. 1. (1985).

Distribution China (WC Guangxi)

Description Rhizome: creeping terete, diameter 3 - 6 mm.
Leaves: solitary, to ca. 40 cm; cataphylls undescribed; petiole 9 - 17.5 cm; lamina oblong-elliptic to elliptic-lanceolate, 14 - 21 cm long x 6 - 8.5 cm wide.

Peduncle: 1.5 - 5 cm long with ca. 4 bracts, erect; flowers solitary.

Perianth [Perigone]: subcampanulate, greenish-cream with blue-purple speckles; tube 0.8 - 1 cm long x 1.3 - 1.6 cm diameter; lobes (normally) 8, erect, triangular-lanceolate, 9 - 10 mm long x 6 - 7 mm wide, adaxially with 2 papillose keels distally, basally expanded inward forming subulate appendages connate into a ring and partially closing the tube entrance.

Stamens: 8, inserted at base of perianth tube, subsessile; anthers ovate, ca. 4 mm.

Pistil: [two forms illustrated?] 8 - 10 mm long; stigma peltate, orbicular, 1 - 1.2 cm in diameter, almost filling the perianth tube, adaxially intricately 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.

Fruit: undescribed.

Phenology: flowers June

2n = 38

Comments The structure of the stigma shown in K-Y Lang's drawing cannot be reconciled with Li Guangzhao's drawing. In K-Y Lang the stigma appears an almost petaloid structure on a slender 6 mm long style. In Li Guangzhao the stigma is apparently sessile and abaxially bowl-shaped with radial ridges emergent at the edge.
