or pinnatisect with the pinnules somewhat dimidiately obovate lobed 

 and either (usually 3-) lobulate or coarsely crenate at the tips. Sori 

 large, with the base of the semi-orbicular membranous indusium 

 •06-- 07" diam,, impressed and hence clearly visible on the upper side, 

 the sporangia when ripe usually projecting beyond the margin, 

 usually 1-6 sori to a pinnule or segment and lower pinnules often 

 barren. 



Hazaribagh, repeatedly collected on the top of Parasnath 4000 ft. ! but nowhere 

 else in our province. Fr. Sept.-Nov. 



2. H. pulchra, Diels. Syn. Leucostegia pulchra. Bedel. ; DavaHia 

 pulchra, Don ; Davallia chsetophylla, Wall. 



A very beautiful fern with wide creeping rhizome clothed with broad 

 rounded often peltately attached scales. Fronds glabrous very 

 delicately 3-4-pinnate or (from the rhachides being narrowly winged) 

 -pinnatilid, ovate or sub-deltoid in outline, 5-15" long by 3-5-8" broad 

 and with a slender naked stipes 4-8" long. Ultimate pinnules ovate 

 or elliptic pinnatifidly cut into lanceolate segments with few short 

 linear mostly very acute lobes. Sori mostly broader than long sub- 

 marginal, -02" diam. 



On rocks and trees. Rare. Parasnath, J.D.H. ! Fr. Sept.-Oct. 



7. MICROLEPIA, Presl. 



Rhizome creeping, hairy.. Fronds scattered or 2-ranked along the 

 rhizome, not articulate, l-mors pinnate, veins simple or pinnately 

 forked with branches or venules free. Sori terminal on the dilated 

 end of the venule which forms an evident receptacle often visible 

 from the upper surface, marginal or intra-marginal. Indusium mem- 

 branous, semi-cup-shaped, attached by base and sides. Sporangia 

 very numerous. 



Fronds simply pinnate, nearly glabrous . . . . .1. marginalis. 

 Fronds 2-3-pinnate, hairy both sides 2. speluticce. 



1. M. marginalis, Hance. Syn. Davallia marginalis, Bsiker. 



Fronds simply pinnate and lobed, lanceolate or linear-lanceolate to 

 broadly ovate-lanceolate {Bedd.), firm, 18-24" long by 6-12" broad 

 (9-15", Bedd.), and with a grey scaberulous nearly glabrous stipes 8" 

 or more long. Rhachis and costse beneath closely pubescent. Lowest 

 pinnae reduced to 2-3 rounded toothed pinnules. IMedian pinnae 

 longest, attaining (in our specimens) 6-7" by -7 --9" linear-lanceolate 

 acuminate, shortly stalked, obliquely cuneate and much stronger on 

 the acroscopic side of the base, lobed half-way down except on the 

 serrate acuminate apex, lobes broadly oblong rounded rarely acute, 

 crenate or dentate, each lobe with a pinnate or sub-dichotomously 

 branched vein, the venules sometimes again divided in the larger lobes, 

 fertile venules expanded at the tip into a receptacle visible and appear- 

 ing brown from above. Sori solitary opposite the sinuses of the 

 acuminate apex and intra-marginal, 2-5 sub-marginal on the lower 

 lobes, -06" diam., margin of indusium slightly crenate and sparsely
