180 DAVALLIA. 



Halj. Moluccas, Roxburgh. Amhoyna, A. Smith, in Herb. Banks, (and 

 in Herb. Hook, from P. B. Webb, Esq.) Offack, Terre des Papons, D'Ur- 

 ville, (in Herb. Hook.) — Stipes a foot and raove long, erect, flexuose, rather 

 slender, n<?id, glossy brown, almost black below. Frond a foot or more 

 high ; readily distinguished among this group of Ferns by the subcoria- 

 ceous texture, long attenuated lower ])inna2, and the lanceolate, acuminate 

 pinnules, together with the position of the sori in the sinus of the seg- 

 ments. I am induced to consider Boi-y's Dicksonia strainitiea to belong to 

 this, rather than Labillardiere's plant; not only from the description, but 

 from my possessing a specimen from D'Urville, of our present Davallia, 

 gathered at Offack. 



67. D. incequalis, Kze. ; caudex creeping, frond ample 

 tripinnate glabrous coriaceo-membranaceous rather glossy 

 full green when dry, ultimate pinnae distant obliquely sub- 

 rhonibeo-lanceolate or ovato-lanceolate the base attenuato- 

 cuneate subpetiolate acute or acuminate inciso-lobate and 

 serrate, the upper ones coadunate into a narrow pinnatifid 

 apex the lobes very acute, veins prominent, ultimate rachis 

 slightly winged, sori generally at the base of an axillary 

 tooth, involucre half-cup-shaped subcuneate (i. e. the base 

 attenuated) broader in age. — Kze. Syn. PI. Crypt. Poepp., 

 p. 87. PI. Poepp. in Herb. Hook. — a. major; idtimate 

 pinnae 1 — 2 or 3 inches long. (Tab. LVII. B.) Davallia 

 alata, Hewarcl, May. of Nat. Hist. 1838, p. 465. — ^. inter- 

 media; ultimate pinnae f to g- an inch long. — y. minor; 

 ultimate pinnae ^ an inch rarely exceeding an inch long, of a 

 rather more rigid texture. (Tab. LVIII. A.) Microlepia alata,

Hab. a. Peru; Maynas, Poeppig ; V MXgo-A, Mathe^vs, n. 1097. Brazil; 

 Corcovado, and damp woods in the Organ mountains, Gardner, n. 202 ; 

 Ilhios, (Moricand). Trinidad, Lockhart, Aldridge. — /3. Jamaica, Hew- 

 ard. Wiles. Ceylon, Mrs. Gen. Walker. Isle of Mindoro, Cuming, n. 

 360 (frond more membranaceous). — y. Luzon, Cuming, n. 119. Herb. 

 Carmichael (without locality). — So different is what I here call var. y. from 

 the type of the species, in the size of its pinnules, that when I had the 

 figure prepared of it, I did not suspect its belonging to the same species. A 

 pretty extensive suite of specimens, however, both from the old and the new 

 world, lead me to the conclusion that they are merely forms of one and the 

 same species ; and Mr. J. Smith has expressed a similar opinion. The 

 species is clearly defined by Kunze, who alludes to its supposed alfiuity to 

 D. distans, Kaulf., a Fern indeed unknown tu him, as it is to me. Our 

 plant bears no inconsiderable resemblance to our Dicksonia Plumieri, but 

 the pinnules are at all times much smaller, more divided, and the invo- 

 lucres are truly those of Davallia. 



fully studied, even did not a copy of Dr. Wallich's own MSS. in my pos- 

 session abundantly prove the fact, and which fully justifies me in sacredly 

 preserving his names, whenever I do not find a clear right of priority 

 in favour of any other person.
