秦氏金星蕨 qin shi jin xing jue

Plants 35-60(-75) cm tall. Rhizomes short and erect. Fronds clustered; stipes 15-30 cm, bases occasionally with lanceolate scales and sparsely grayish white multicellular spreading acicular hairs, dark brown proximally, distally brownish stramineous, sparsely shortly hairy or subglabrous; laminae oblong-lanceolate, 20-30 × 10-13 cm, not tapering to bases, pinnate-pinnatifid, acuminate and pinnatifid at apices; pinnae 12-15 pairs, sessile, spreading, proximal ones not shortened, reflexed, pinnae from middle of lamina downward lanceolate, 5-8 × 1.4-1.7 cm, bases slightly broadened, rounded-truncate, symmetrical, pinnatifid and reaching both narrow wings of costae, apices acuminate; segments 8-15 pairs, proximal ones oblong, 4-8 × 3-4 mm, slightly tapering to and rounded-truncate at apices, sometimes angular and entire on sides. Veins evident, lateral veins simple, 3-5 pairs per segment, proximal pair arising from high above base of costules. Laminae thickly herbaceous, when dry grass-green or dark green, abaxially with sparse reddish purple spherical glands, along costae and veins with more grayish white spreading acicular hairs, adaxially along grooves with dense acicular hairs and appressed short setae, also mixed with multicellular spreading acicular hairs. Sori orbicular, dorsifixed at middle of veinlets between costules and margins, 2-5 pairs per segment; indusia large, orbicular-reniform, brown, thickly membranous and separated from each other and with grayish white acicular hairs.

● Wet places in dense valley forests, forests at foot of mountains; 300-500 m. N Fujian, Guangdong, S Jiangxi.

Parathelypteris chingii is similar to P. japonica but differs by plants shorter and smaller, stipes with spreading acicular hairs at bases, pinnae with spreading fine and long acicular hairs abaxially, and indusia separated from each other.

1 Plants 35-60 cm tall; pinnae sessile, abaxially along costae and veins with grayish white acicular hairs, and adaxially along costal grooves with appressed short setae and multicellular acicular hairs, rachises with denser acicular hairs.   12a var. chingii
+ Plants to 75 cm tall; proximal pinnae stalked, along costae and veins with dense short hairs except long acicular hairs abaxially, rachises with dense setae adaxially, with sparse grayish white fine and long acicular hairs abaxially.   12b var. major
