2. H. oligocarpum, sp. nov. 



Ehizome long, wiry, harsh, creeping, blackish, bare, with a 

 few rootlets. Stipe 2fin.-3in. long, filiform, wiry, naked, 

 dark-brown. Frond erect, fin.-lin. apart, glabrous, sub- 

 ovate-acuminate, 2-|-in.-3in. long, 2 in. -4 in. wide, rather 

 irregular in outline, bipinnate, membranous, decurved, bright 

 emerald-green; pinnae free; midrib, rhachis, and subrhachises 

 prominent, slender, blackish throughout, winged, denticulate- 

 serrate, the wings of subrhachises broader, secondary pinnae 

 rather distant ; lobes linear, sharply serrate, teeth distant, 

 tips obtuse - truncate, sometimes denticulate. Involucres 

 large, few, solitary, supra-axillary in upper secondary pinnae, 

 and extending to tip of frond, free, pedicelled, erect and 

 drooping ; pedicel often winged on one side, with a short 

 lobe or tooth on the other ; valves large, broadly obovate, 

 entire, smooth, shining, cut half - way down, immature 

 closed and much curved together, mature open, gaping. 

 Eeceptacle stout, largely exserted ; capsules few, red.

 H. Hill. 



Obs. A species allied to -H". multifidinn, but differing in 

 several characters, particularly its irregular and open pinnae 

 and pinnules, its few solitary pedicelled sori, and largely 

 decurved involucre ; the cells, too, of its frond are different, 

 as shown in the plate of the type specimen oi H. multifidum, 

 Sw. (Hk. and Grev., Ic. FiL, t. 167), and Baker describes its 

 sori: "1 to 12 to a pinna, terminal on the lateral segments 

 of the upper pinnae on both sides " (Sy. FiL, p. 69). 



Genus 18. Asplenium, Linn. 

 1. A. symrnetricum, sp. nov. 



Plant small, tufted, upright, drooping ; rootstock com- 

 pact, 8-10 fronds. Stipe 1 in. long, greenish, subsucculent, 

 thickish, clothed at base with long deltoid acuminate scales. 

 Frond subovate-lanceolate, 3 in. long, 1 in.-liin. wide, bipin- 

 nate, membranaceous, glabrous, dark-green; rhachises scaly, 

 and pinnae sparsely so, with smaller scattered scales ; pinnae 

 alternate, oblong, obtuse, regular, 9-10-jugate, close but not 

 overlapping, each having 3-4 pairs of pinnules ; pinnules all 

 stalked and distant, free throughout, cut to base into 4-5-6 

 lobes; the lowermost pinnule on upper side of subrhachis, and 

 always the largest, 6-lobed ; lobes long, linear and linear- 

 lanceolate, flat, narrowly margined, very acute, rarely bifid, 

 tips pointed, single-veined ; veins central, not extending to 

 margins, their tips prominent on upper surface, white. Sori 

 general throughout ; one cluster on vein in each lobe red. 

 Involucre rather large, white, oblong-lanceolate, ends acute ;
