J ra. br. ; texture herbaceous, both surfaces bright-green, nearly naked ; rachis 

 slender, straw-colonred, nearly naked ; veins about 6 on each side in the lower 

 lobes, with sori on each reaching two-thirds of the way to the edge, the lowest 

 ^ in. 1. ; invol. broad, brown, tumid. — A. Schkuhrii, Hh. Sp. 3. p. 251. — )3, Oldhami; 

 Jr. smaller, lanceolate, 4-6 in. 1., 2-3 in. br. ; rachis straw-coloured, polished, naked ; 

 pinnce 1-]^ in. 1., blunt ; hhes blunt, only 3 veins on a side in each. — y,coreanum ; 

 Jr. the same size as in ;8, but only the lower half pinnate, the rachis and stem 

 rather chafiy and villose. 



Hab. Japan, China, Formoaa, Himalayas. — The Samoan and Fijian D. congruwn, 

 Bracli. t. 18, comes very near to this. In a specimen from Mr. Powell, the subs^nce is 

 very thin, the rachis naked, the lobes J in. deep, J in. br., veinlets 5-6 on each side, most 

 of them again forked ; and a similar plant grows in the Sandwich Islands. 



227. A. (Dipl.) Thwaitesii, A. Br. ; rhizome wide-creeping ; st. 6 in. 1., slender, 

 green, densely clothed with strong white woolly hairs ; fr. 1 ft. 1., 4 in. br., with 

 8-10 distant pinnce beneath the pinnatifid apex, the largest 2 in. 1., f in. br., cut 

 down two-thirds of the way to the rachis in oblong crenulated lobes J in. deep, 

 2 lin. across ; rachis flaccid, villose like the stem ; texture herbaceous ; colour pale- 

 green, and both surfaces also villose ; vdns 4 on each side in a lobe, simple ; sori 

 reaching halfway to the edge, the lowest about a line long. — Hh. Sp. 3. p. 250.

Hab. Ceylon. — Intermediate between the preceding and following. 



228. A. (Dipl.) lasiopteris, Mett. ; rhizome wide-creeping ; St. 6-9 in. 1., firm, 

 erect, dark-coloured, villose ;^. 15-18 in. 1., 6-8 in. br., with 8-10 ^"rencB on each 

 side below the pinnatifid apex, the largest 3-4 in. 1., 1-ly in. br., the lower lobes 

 cut down nearly or quite to the rachis, f-J in. deep, 4 in. br., the point obtuse, the 

 edge distinctly crenate ; texture herbaceous, the dark-coloured rachis and dark- 

 green ^omZ villose on both sides ; veinlets 5-6 on each side, simple ; lower sori

Hab. Canton, Java, and the Neilgherries, well figured by Beddome, t. 160. — This is 

 the D. decussatum of English gardens ; but our original specimen from Wallieh is jl. japo- 

 nicum. It comes near the two preceding, and the three are weE marked by the character 

 of the rhizome. 



229. A. (Dipl.) speciosum, Mett. ; St. tufted, 1 ft. or more 1., firm, erect, straw- 

 coloured or brownbh, nearly naked ; Jr. 1-2 ft. 1., 8-12 in. br., with 10-20 pairs 

 of pinruB below the pinnatifid apex, the lower ones often stalked, 4-6 in. 1., 1-lJ 

 in. br., the apex much acuminated, the edge lohed, the lobes reaching down two- 

 thirds of the way to the rachis or more, close, J in. br., slightly toothed, the base 

 truncate or slightly cuueate ; texture herbaceous but firm ; rachis erect, naked ; 

 v^ns pinnate in the lobes ; sori slender, reaching nearly to the edge.— Diplazium, 

 Blwme. A. acuminatum. Wall., Mett. (non S. & A.). 



Hab. Malayan Peninsula and PhUippinea, Java, Hong-Kong. — This is nearest A . sor&o~ 

 goneme, but the lobes are broader and not so deep, more herbaceous in texture, and dis- 

 tinctly toothed. A plant from Fiji comes very near this, but the pinnae are fewer, thinner, 

 the lower ones distinctly stalked, and the lobes broader ; and one from Bichmond River, 

 Australia, sent by Dr. Mueller, only differs by the lobes being rather broader and shallower. 

 A specimen of Blume's plant from Miquel quite agrees with Wallich's examples of 

 acuminatum. 



230. A. (Dip).) Welmtschii, Hk. MSS. ; st. 1 ft. or more 1., firm, erect, straw- 

 coloured, naked ; ^. 18 in. 1., 9 in. br., the lower pinnce 6-7 in. 1,, 1-1§ in. br., 

 the point acuminate, the edge slightly lobed above, cut down in the lower part 

 half or two- thirds of the way to the rachis ; the lobes not quite contiguous, f in. br., 

 nearly entire, the base sessile, truncate ; texture herbaceous ; veins distantly pin-
