incntose with jointed soft fornipiiious hairs, not at all scaly, sendint;; down 

 nunieruus hairy fibrous roots from the base. Stipes (> — (-( inches hijfli, 

 maho}!^any brown, sliininp : main rachis the same, flcxnose and slender. 

 Frond H inches to a foot lonp, membranaceous, but very firm, tliriee pin- 

 nated. Sori large in inoportion to the scfrniculs, often ecjual in breadth to 

 the segments on which they are placed. Tlic colour of the frond is brown- 

 ish green, slightly glossy, much paler below. Mr. Heward has given a very 

 appropriate name to the species in his herbarium, which we would gladly 

 adopt, but tliat Mr. Colenso's name is sent to us as published in the 

 ' Tasmanian Journal of Science ' in a number jnobably which has not yet 

 reached this country. 



20. D. ntei)thranulosa, Wall.; caudex hispid with very long 

 slender siibidale rigid nienibranaccous scales, frond small 

 very thin and membranaceous ovato-lanccolate and as well 

 as the slender sti])es and rachis pubescenti-hirsute bipinnate, 

 jiiuniu alternate lanceolate their rachis winged, pinnidc^s lan- 

 ceolate ])innatifid, the segments ovato-lanceolate siibfalcate 

 very acute entire or rarely toothed, involucres small ovato- 

 subrotund acute very thin and membranaceous fixed by the 

 broad base the rest free. (Tab. LIII. A.) Wall. Cat. nl2do. 



Hab. Nepal, Wallich. — A small and very delicate species, with the habit 

 of Ci/stoptn-is, but the sorus is at the apex of a vein, although the involu- 

 cres are more sharp-pointed than is usual with Davallia. Caudex with 

 long ferruginous narrow subulate scales. Stipes 2 — 3 inches high, and, as 

 well as the rachis, which is winged above, very slender, almost filiform. 

 Frond a span long. Primary pinnaj 2 inches long, lanceolate, of a red- 

 brown colour. 



21. D.falcinella, Pr. ; caudex creeping rather thick branch- 

 ed densely covered with spreading very long subulato-setace- 

 ous scales paler at the apices of the caudex, frond deltoideo- 

 cordate sub-membranaceous 4-pinnatifid (rachis everywhere 

 winged), ultimate pimniles oblong pinnaiifid, segments lan- 

 ceolate subfalcate acute entire, in the fertile specimens bi- 

 dentate the teeth unequal spreading, the sorus occupying the 

 sinus between two veins but not reaching to the margin, in- 

 volucre large in proportion to the size of the segments nearly 

 orbicular flat truncated at the apex, rachis not winged. —

Hab. Malay Islands, Sorzogon (Pres/). Leyte, Cuming ^n.'M)\. — A 

 small elegant species, with a singularly crinite caudex and a small frond 

 (4 — .') inches long), which exhibits a considerably different appearance in the 

 fertile and in the sterile state : in the former the ultimate lacinire dividing 

 into two unequal spreading slightly incurved teeth, between which, at a lit- 

 tle distance from the margin, the large flat involucre is inserted. Tliis in- 

 volucre is scarcely fixed by a sufficiently narrow base to justify the species 

 being placed in this division, yet the habit of the plant and the Hat (not 

 convex or semiterete) involucres, seeiu rather to point out its affinity to be 

 with the i)resent.
