﻿300 34. DAVALLIA. § 2. GOLI'OSORIA. 



Davallodps graiiwiatosorum, Copel, I. c, lab. VI : Indusiiim narrowly semi- 

 cylindrical, naked; lower pinnae hardly reduced. 



Davallodcs liirsulum, Copel.: Indusium semicupuliform; lower pinnae mo- 

 deralely reduced. 



Davallodes gymnocarpimi , Copel., 1. c, lab. V: Indusium broader Ihan long, 

 altached by the base (as in Humala): lower pinnae gradually much reduced, 



Philippines, Celebes, Borneo. 



(4) D. H^ortlialsii, Mett., Linn., XXXVI, 142. 



Rhizome probably creeping. Fronds + 45 c.M. long, ovale, acuminale, 

 4-pinnatipartite ; main rachis slramineous, canaliculate at the upper side. Pin- 

 nae petiolate, trapezoidal or oblong-lanceolate, the apex curved and caudalo-acu- 

 minate. Pinnulae shorl-slalked, trapezio-ovate or oblong, the apex short, nar- 

 rowed, obtuse. Ullimate divisions Irapezio-oblong, obtuse, pinnatipartite at 

 the base. Lobes spathulale-cuneale, with the upper edge crenate. Texture 

 thinly chartaceous, firm ; veins thickened at the apex, covered with a calcare- 

 ous scale on Ihe upper surface of the frond. Sori unknown. 



Sumatra, Singapore.

 Fil., I, tab. XLIX, B. 



Rhizome stout, the scales dense, pale-brown or whitish, linear. Stipes 

 erect, wiry, 10—20 c.M. long. Fronds 20—50 c.M. long, 10—20 c.M. broad, 

 deltoid, 5 — 4-pinnatifid. Pinnulae of the lower pinnae lanceolate-deltoid, 5 — 

 7'/2 c.M. long, 2% c.M. or more broad. Lower segments toothed in the barren 

 fronds, cut down nearly to the rachis in the fertile ones. Texture coriaceous. 

 Sori large ; indusium half-cupshaped, ± as long as broad, very shortly attached 

 on the sides nearly as in Humata, the apex whether or not reaching the 

 margin.

(6; ». Liobbiaua, Moore, Hk. Bk., Syn. Fil., 94. 



Fronds 30—43 c.M. or more long, 15-25 c.M. broad, lanceolate-deltoid, 

 2 — 3-pinnatiHd; main rachis slightly winged above. Lower pinnae 10 — 15 

 c.M. long, + 5 c.M. broad,, lanceolate-deltoid, acuminate, cut down to the 

 rachis in the lower part into linear- or deltoid-oblong, blunt segments, only 

 the lowest of which are deeply tool bed. Sori copious, placed obliquely in 2 

 long rows in the pinnulae near the edge; indusium broader than deep. 



Borneo.
