NEW FEENS FROM WESTERN CHINA. 177 



117.* N. (Lasteea) Fordii, n. sp. — Rhizome short-creeping, 

 densely clothed with large bright brown membranous lanceolate 

 paleae, like those of N. odoratum. Stipe 4-6 in. long, slender, 

 flexuose, stramineous, scaleless, glabrous. Frond fragile, mem- 

 branous, pale green, slightly pubescent, deltoid, 4-pinnate, 6-8 in. 

 long and broad; pinnae deltoid, the lowest much the largest and 

 much produced on the lower side ; ultimate segments oblong, 

 crenato-pinnatifid, cut away on the lower side at the base. Veins 

 free, distinct, erecto-patent, one running into each final lobe. Sori 

 medial, dorsal on the final veinlets. Indusium pale, reniform, 

 membranous, persistent. — North Eiver, Kwantung Province, Ford 

 104 ! Habit and cutting of N. odoratum Baker, but membranous 

 and finely pubescent, with much smaller glabrous indusia. 



169.* N. (Eunephrodium) rampans, n. sp. — Ehizome hypo- 

 gseous, wide-creeping. Stipe naked, stramineous, -^ ft. long, 

 deeply grooved down the face. Frond oblong- deltoid, simply ^ 

 pmnate, rigidly subcoriaceous, glabrous, about a foot long, 8-10 in. 

 broad. Pinnae about 17, distant, sessile, lanceolate, 5-6 in. long, 

 ^-| in. broad, crenate, the lowest not reduced. Main veins ^-^ in. 

 apart ; veinlets 6-7 -jugate. Sori copious, small, subcostal. In- 

 dusium minute, fugacious. — Hupeh, Henry 7844 ! Allied to N. 

 ^ sopheroides and zmitiim. 



Polypodium gymnogrammoides Baker. Henry 6440. 



P. malacodon Hook. Henry 6170. New to China. 



297.* P. (Phymatodes) involutum, n. sp. — Rhizome short- 

 creeping; basal paleae lanceolate, nearly black. Fronds rigid, 

 linear, contiguous, sessile, simple, reaching a foot in length, ^-^ in. 

 broad at the middle, tapering to base and apex, bright green, rigid, 

 with revolute edges. Costa broad and distinct ; veins quite hidden. ■^ 

 Sori oblong, confined to the upper half or third of the frond, filhng 

 up the whole space between the midrib and involute margin. — 

 Hupeh, Henry 6859 ! Allied to P. Leivisii Baker in Journ. Bot. 

 1875, 201, gathered by Dr. Shearer in the Province of Kiu-kiang. 



348.* P. (Phymatodes) subhastatum, n. sp. — Rhizome slender, 

 creeping to a length of a foot or more ; paleae small, lanceolate, 

 membranous, bright brown. Stipes very short. Fronds simple, 

 ovate or deltoid, hastate or truncate at the base, acute, 1-2 in. long, ^ 

 moderately firm in texture, green and glabrous on both surfaces, 

 decurrent in a narrow wing halfway down the stipe. Veins anasto- 

 mosing copiously in irregular hexagonal areolae with free included 

 veinlets. Sori globose, superficial, placed in a single row midway 

 between the midrib and margin in the upper part of the frond. — 

 Hupeh, Henry 5450 ! Midway between P. rostratum and Spectrum. 



11.* Gymnogramme (Leptogramme) gigantea, n. sp. — Stipe 

 1^ ft. long; basal paleae large, lanceolate, crisped. Frond ample, 

 deltoid, tripinnatifid, moderately firm, green and glabrous on r 

 both surfaces. Central pinnae oblong-lanceolate, reaching a length 

 of 1-^2 ft. and a breadth of 6-8 in. ; pinnules sessile, lanceolate, 

 f-1 in. broad, cut halfway down to the midrib or more into oblong 

 obtuse segments ^ in. broad. Veins copiously pinnate in the 

 tertiary segments ; veinlets erecto-patent, often forked. Sori
