228 ON TWO RECENT COLLECTIONS OF FERNS FROM WESTERN CHINA. 



' (26*). A. (Polystichum) capillipes, n. sp. Stipes densely tufted, 

 thread-like, naked, 3-4 in. long; basal paleae lanceolate, brown, 

 membranous. Lamina lanceolate, 2-3 in. long, not more than 

 \ in. broad, deeply bipinnatifid, moderately firm in texture, green, 

 glabrous, with many minute linear dark brown palese on the main 

 rachis. Pinnae lanceolate, \ in. long, most of the pinnules lanceo- 

 late-aristate and 1-nerved, but the lowest on the upper side much 

 larger than the rest and deeply pinnatifid. Sori one to a pinnule. 



Indusium large, convex, persistent, membranous. — Mount Omei, 

 Faber 1086. Not nearly allied to anything already known. The 

 large bullate membranous indusium recalls A. craspedosornm. The 

 habit is most like that of a finely divided form of Aspleniam Jon- 

 taniim. 



A. arhtatum Sw. Patung district, Henry 3678. Mount Omei, 

 , 8500 ft., Faber 1082, 1083. 



i??3$ (42*). A. (Polystichum) caruifolium, n.sp. Caudex stout, 

 erect. Stipes densely tufted, slender, stramineous, 2-8 in. long, 

 with a few small lanceolate paleae. Lamina lanceolate, decompound, 

 9-12 in. long, H in. broad, moderately firm in texture, bright 

 green, glabrous ; rachis naked, slender, stramineous. Pinnse 

 lanceolate, multijugate, |-1 in. long, % in. broad, much cut away 

 on the lower side ; lower pinnules deltoid, bipinnate ; final segments 

 lanceolate-aristate, 1-nerved, 146th to 1- 12th in. long. Sori not 

 more than one to each final segment, various in position. Indusium 

 small, peltate, glabrous.— Mount Omei, 3000-3500 ft., Faber 1021. 

 A very distinct and beautiful species, most like Asplenium tenuij'oliitm 

 in habit. 



A. fakatwm Sw. Mount Omei, Faber 1060. Patung district, 

 Henry 3686, 8687. Yang-tze-kiang, Faber 1046 ; and a variety 

 like the Himalayan A . caryotideum Wall., with few very large pinnae, 

 on Mount Omei, at 5000-8000 ft., Faber 1058. 



Xephrodium decnrsivo- pinna -turn Baker. Patung district, Henry 

 3679. — X. hirtipes Hook. A form intermediate between the type 

 and the Japanese X. Dickhmi Baker, on Mount Ornei, Faber 1047. 

 — X. IHekimii Baker. Patung district, Henry 3677.— .V. graeilescen* 

 Hook. Mount Omei, Faber 1052.— X ClarM Baker. Mount Omei, 

 Faber 1003. An East Himalayan species, new to China. 



<tf (70*). N. (Lastbea) unifurcatum, n. sp. Stipe naked, dull 

 brown, 12-15 in. long/ Lamina oblong-lanceolate, l|-2 ft. long, 

 8-10 in. broad, bipinnatifid, membranous, green and glabrous on 

 both surfaces ; rachis dull brown, obscurely paleaceous. Pinnse 

 lanceolate, the lowest not reduced, 5-6 in. long, 1-1J in. broad, cut 

 down regularly to a narrow wing into parallel, oblong, obtuse seg- 

 ments £ in. broad. Veinlets of the pinnules 7-8-jugate, forked* 

 Sori medial. Indusium small, glabrous, persistent.— Mount Omei, 



3500 ft., Faber 1051. 



X. lacerum Baker. Patung district, Henry 3680.— X. odoraUw* 

 Baker. Wushan Gorge, Faber 1084. — X. intermedium Baker. 

 Mount Omei, 8500 ft., Faber 1054, 1062. — X. eopkoroidee Dcsv. 

 Mount Omei, Faber 1078. — X. eicutarium Baker. Mount Omei, 

 Faber 1074. Common m the Eastern Himalayas. New to China.
