ON TWO RECENT COLLECTIONS OF FERNS FROM WESTERN CHINA. 229 



(1*). Polypodium (Phegopteris) gymnogrammoides, n. sp. 

 Rootstock creeping below the surface. Stipes spaced out, slender, 

 stramineous, naked, fragile, 4-5 in. long. Lamina oblong-deltoid, 

 5-6 in. long, about 3 in. broad, membranous, green and glabrous 

 on both surfaces, cut down to a narrow wing to the main rachis 

 into lanceolate crenate pitmie $ in. broad, the lowest pair deflexed, 

 as in P. Phegopteris. Veins in pinnate groups, with about 2 very 

 ascending veinlets on a side. Sori oblong, in a single series on 

 each side of the midrib of the pinnae.— Mount Omei, 3500 ft., 

 Faber 1036. Nearly allied to the Japanese P. Krameri Franch. et 

 Savat., figured lately in Hooker's 'Ieones,' tab. 1668. 



^0(13*). P. (Phegopteris) omeiense, n. sp. Eootstock creeping 

 widely below the surface. Stipe naked, a foot long. Lamina 

 oblong-lanceolate, bipinhatifid, a foot or more long, 4-5 in, broad 

 at the middle, reduced at the base, moderately firm in texture, 

 green and rather hairy on both surfaces ; rachis pubescent, not at 

 all paleaceous. Pinme sessile, lanceolate, 3-4 in. long, f in. broad, 

 cut down to a narrow wing into entire linear-oblong segments ^ in. 

 broad. Veinlets simple, distinct, 8-9-jugate. Sori small, medial. — 

 Mount Omei, Faber 1059. Differs from the Himalayan P. appen- 

 diculatum Wall, by its creeping rootstock and medial sori. 

 p^ (19*). P. (Phegopteris) braineoides, n. sp. Lamina very lar_ 

 oblong, bipinnate, 1| ft. broad, moderately firm in texture, green 

 and glabrous on both surfaces ; rachis quadrangular, not paleaceous. 

 Central pinnae lanceolate, nearly a foot long, lj-li in. broad, cut 

 down nearly or quite to the rachis into linear-oblong entire segments 

 i in. broad. Veins simple, about 20 on a side. Sori costal, con- 

 fluent.— Mount Omei, 2500 ft., Faber 1022. Very near the Tropical 

 American P. decassatum L. 



:(26*). P. (Phegopteris) stenopterum, n. sp. Stipes stra- 

 mineous, 6-8 in. Ion*, with only a few lanceolate brown pale®

towards the base. Lamina oblong-lanceolate, membranous, bi- 

 pinnatifid, l|-2 ft. long, 7-8 in. broad, green and glabrous on both 

 surfaces; rachis stramineous, not paleaceous. Pinnae lanceolate, 

 sessile, the lower 5-6 in. long, l£-l$ in. broad, cut down to a 

 narrow wing into oblong entire or inciso-crenate segments £ in. 

 broad. Veins pinnate opposite the lobes of the pinnules, with not 

 more than two simple veinlets on a side. Sori uniserial in the 

 pinnules, subglobose, placed nearer the midrib than the margin.— 

 Patung district, Henry 3682. Allied to the common Himalayan P. 

 distans Don. 



\ (43*). p. (Phegopteris) alcicorne, n. sp. Caudex erect, 

 btipes densely tufted, stramineous, 4-7 in. long, clothed throughout 

 with small ovate unequal-sized brown paleae. Lamina oblong- 

 lanceolate, 3-4-pinnatifid, 8-9 in. long, about 2 in. broad, firm in 

 texture, green and glabrous ; rachis scaly like the stipe. Pinme 

 lanceolate, at most 1$ in. long, 1 in. broad, much reduced on the 

 lower side; final segments non-contiguous, lanceolate, aristate, 

 1 -nerved, £-£ in. Ion*. Sori minute, placed singly near the tip of 

 the segments.— Mount Omei, 3000 ft., Faber 1008, 1009. A very 

 distinct and beautiful species, most like Aspidinmfaniculacettrn Hook, 

 in texture and cutting.
