20. Coniogramme jinggangshanensis Ching & K. H. Shing, Acta Bot. Yunnan. 3: 238. 1981.

井冈山凤了蕨 jing gang shan feng liao jue

Stipe brownish purple, ca. 70 cm × 5 mm; lamina dull green when dry, ovate-oblong, somewhat longer than stipe, ca. 30 cm wide, 2-pinnate, herbaceous, both surfaces glabrous; rachis brownish purple abaxially, brown adaxially. Lateral pinnae ca. 8 pairs, basal pair largest, ovate-deltoid, ca. 35 × 15 cm, stalks ca. 3 cm, pinnate; lateral pinnules 3 pairs, well separated, lanceolate, ca. 15 × 2 cm, base broadly cuneate, apex long acuminate; terminal pinnule much longer than lateral ones, as medial pinnae in shape and size. Pinnae of second pair trifoliolate. Medial pinnae simple, linear-lanceolate, ca. 25 × 3 cm, stalks ca. 1 cm, base broadly cuneate, apex long acuminate; distal pinnae gradually shortened. Terminal pinna larger than adjacent ones. Pinna and pinnule margins serrate, teeth shallow, incised. Veins 1- or 2-forked, occasionally connected forming 1 or 2 areoles; hydathodes extending to tooth base. Sori extending close to lamina margin.

● Evergreen forests by streams or in ravines; 500-1300 m. Fujian, Guizhou, Hunan, Jiangxi, Zhejiang.

Coniogramme jinggangshanensis looks much like C. intermedia and C. japonica. It differs from the former by its larger stature (to 1.5 m tall), the stout teeth of the pinna margin, and the hydathodes reaching only to the tooth bases; it differs from the latter by the pinnae somewhat linear-lanceolate and the veins not forming 2 or 3 rows of areoles along each side of the midrib.

"Coniogramme tsingkangshanensis" (Ching, Fl. Fujian. 1: 90. 1985) belongs here but is a nomen nudum and was not therefore validly published (Melbourne Code, Art. 38.1(a)).
