Hab. Fernando Po, at an elevation of 3,000 ft., G. Mann. fte&restZ/.'gibberbsa, but

Hab. Fiji group ; gathered by Mr. Milne. A very distinct and finely-cut species. 

 Habit of D. trichomanoides, but sori quite different. 



Stenoloma, Fee. Invol. as in Loxoscaphe, but terminal on the seg- 

 ments. Sp. 70-79. Fronds very various in size, but the ultimate segments always 

 cuneate, growing gradually wider from the base to the apex. Scattered throughout 

 the tropics. Odontosoria, J. Smith. This goes with Microlepia into J. /Smith's 

 Desmobrj/a.

 not more than 1 in. 1. ; fr. 4-6 in. 1., J-^ in. br., linear-oblong ; main rachis not 

 branched ; largest pinnce deltoid, ^ in. 1., more than j in. br., cut down to a 

 slender subfiliforin rachis into simple or forked linear-cuneate thinly herbaceous 

 segments ; sori terminal, suborbicular, 1 to each segment. Hk. Sp. I. p. 189. t. 

 50. C., 2 Cent. t. 23.

 flexuose ; fr. 4-8 in. 1., 2-4 in. br., ovate-deltoid, quadripinnatifid; pinnce flaccid, 

 2-4 in. 1., lanceolate-deltoid, the lower pinnl. cut down to a filiform rachis, with 

 deeply-cut pinnatifid or flabellate segm., ultimate divisions linear-cuneate, thinly 

 herbaceous, 1^-2^ lin. 1., less than % lin. br. at the point ; sori small, terminal, 

 suborbicular. ilk. Sp. 1. p. 188. Hk. $ Gr. Ic. t. 238.

 segment. Lindsay a, Mett. Fil. N. Caled. p. 64.
