62. D. (Micro.) pinnata, Cav. ; rhizome creeping, fibrillose ; st. strong, erect, 

 6-12 in. 1. ; fr. 9-15 in. 1., 4-8 in. br., with distant linear slightly toothed pinnce

 lobes. D. Luzonica, Hk. Sp. \.p. 174. t. 60. /. 2. 3. and 5. 



Hab. Malayan Peninsula, Java, and Polynesian Islands. This and the two preceding 

 are very distinct species, easily distinguishable from the rest by their simply pinnate 

 habit and long narrow pinnae. 



53. D. (Micro.) Wilfordii, Baker ; rhizome creeping ; st. 4-6 in. 1., slender, 

 naked, flexuose ; fr. 6-9 in. 1., 2-3 in. br. ; lanceolate, tripinnatitid ; lower pinnce 

 deltoid, stalked, about 1 in. 1., in. br., cut down to the rachis below with broadly 

 ovate-rhomboidal sharply toothed pinnules ; texture herbaceous ; rachis and both 

 surfaces naked ; sori 2 to 6 to a pinnule, apical in the teeth. D. rhomboidea, 

 Hk. 2nd Cent. t. 48. not Wallich. Microlepia Wilfordii, Moore. 



Hab. Japan ; gathered both by Messrs. Wilford and Oldham. This and the next, it 

 will be seen, are very diminutive compared with all the species that follow.

 slender, erect, 3-4 in. 1., pubescent ; fr. 6-9 in. 1., 2 in. br., lanceolate, tripin-

65. D. (Micro.) ciliata, Hk. ; rhizome creeping, covered with soft brown 

 hairs ; st. 3-4 in. 1., firm, erect, pubescent ; fr. 12-18 in. 1., 6-9 in. br., ovate- 

 lanceolate, tripinnatifid ; pinnce spreading, lanceolate, the central ones the 

 largest, 3-5 in. 1., 1^ in. br., cut down to a broadly-winged rachis, with oblong 

 pinnl. cut about halfway down with falcate, mucronate teeth ; texture thinly 

 herbaceous, flaccid ; rachises and under surface softly hairy ; sori 2 to 12 to a 

 pinnule, very small, placed near the centre of the teeth near the base. Hk. Sp.

 1 in. br., linear, cut down about halfway to the rachis, or less, into bluntish 

 oblong lobes, the base above parallel with the stem, that of the lower side 

 obliquely truncate ; texture subcoriaceous ; rachises densely villose and under 

 surface also hairy ; sori 2 to 8 to a lobe, submarginal Polypodium, Thunb.
