D. (Eudavallia) Lobbiana — Eu-dav-al'-li-a ; Lob-bi-a'-na (Lobb's), Moore. 



This stove species, of medium growth, is a native of Borneo. Its fronds 

 are spear-shaped, twice or three times pinnatifid (cut nearly to the midrib), 

 1ft. to IJft. long. Gin. to 9in. broad, and provided with a racliis (stalk of the 

 leafy portion) that is slightly winged above. Their lower leaflets, 4in. to 6in. 

 long and 2in. broad, are cut down to the rachis into blunt segments, only 

 the lowest of which are deeply toothed. The abundant sori (spore masses) 

 are placed obliquely in two long rows on the pinnules (leafits) near the edge, 

 and covered by involucres that are broader than deep. — Moore, Index 

 Filicum, p. 206. 



D, lonchitidea — lonch-it-id'-e-a (Lonchitis-like). A garden synonym for 

 D. platyphylla. 



D. (Eudavallia) Lorrainii — Eu-dav-al'-li-a ; Lor-rain'-i-i (Lorrain's), Hance. 



A stove species, native of the Malayan Peninsula, producing from a rhizome 

 (prostrate stem) as thick as a quill, and covered with nearly black scales, 

 triangular fronds, 6in. to 12in. long, borne on naked, brownish stalks Sin. to 

 4in. long. These fronds are four times pinnatifid (cleft nearly to the midrib) ; 

 their final lobes are ligulate (strap-shaped), of a somewhat leathery texture, 

 and have each a sorus (spore mass) disposed at their base on the inner side.

D. (Microlepia) majuscula — Mi-crol-ep'-i-a ; ma-jus'-cul-a (rather large), 

 Lowe. 



A strong-growing, stove species, native of Ceylon, with fronds of a 

 somewhat leathery texture and pale green colour, 2ft. to 3ft. long, borne on 

 erect, naked stalks 6in. to 12in. long, and produced from stout, creeping 

 rhizomes (prostrate stems), that are densely covered with silky whitish hairs. 

 The lower leaflets, 9ui. to 12in. long and 3m. to 4in. broad, are spear-shaped, 

 and di^dded into pinnules (leafits) of similar form cut down nearly or quite 

 to the rachis (stalk) into blunt, shghtly- notched, oblong lobes. The small 

 and abundant sori (spore masses) are disposed from two to twelve to a 

 segment, and are situated at the base of each loh^.—Hooker, Species Filicum,
