cm. high, ghibroii.s; fronds 20 to .30 em. liigh, about ."> cm. broad, rachis 

 winged througliout; segments broadly or narrowly ovate, acute, contracted 

 at base, margin shallowly lobed by the soriferous projections, coriaceous, 

 glabrous; veins inconspicuous.

(2) L. pumila Blume. Flora Java; T. 2, Tab. 94. Rhizome as in the 

 preceding; stipe about 10 cm. high, glabrous; frond 20 to 30 cm. high, 

 about 7 cm. broad, rachis winged throughout; segments lanceolate, obtuse, 

 hardly contracted at the base, lobed by the soriferous projections, firm 

 but pellucid; veins conspicuous. Blume's figure of this species (and of 

 the preceding as well) is unaccompanied by any description; the most 

 conspicuous difference between them seems to me to be in the form and 

 apex of the segments, and I have used his names for my plants on the 

 assumption that that difference is diagnostic. The difference in texture 

 would be less easily figured.

(,5G) PHOTINOPTERIS J. Sm. 



Rhizome creeping; frond pinnate, the lower pinnae sterile, each subtended 

 by a stipule-like outgrowth, the upper fertile, very narrow, all articulate 

 to the rachis; veins anastomosing, with free included veinlets in all 

 directions; sori occupying the entire under side of the fertile pinnae. 

 Epiphytic. The sterile plants are readily recognizable by the auricles 

 subtending the pinnae. 



(1) P. speciosa (Bl.) J. Sm. Rhizome bluish, clothed with dirty- 

 brown fibrillose scales; stipe hardly 1 cm. high, glabrous arid brown, like 

 the rachis; sterile pinnae 10 to 15 cm. long, half as broad, ovate, abruptly 

 acuminate, subcuneate at the base, entire, coriaceous, glabrous; main veins 

 and cross-veinlets forming large areolae evident, veinlets forming smaller 

 areolae inconspicuous; fertile pinnae 10 to 15 cm. long, 3 mm. broad, 

 deciduous. A form with a single fertile pinnae was named P. simplex J. Sm.

(57) DRYOSTACHYUM J. Sm. 



Rhizome stout, creeping, scaly; fronds pinnatifid, the segments articulate 

 to the rachis; venation evident, with major, divided into minor areolae, 

 with free included veinlets; sori only on the contracted upper part of 

 the frond, coalescing so that each major areola includes a single cushion 

 of sporangia. Epiphytic, with large, conspicuous fronds, more or less 

 clustered into nests. Intimately related to Drj'naria. 



(1) D. splendens J. Sm. Fronds sessile, the lower part brown, rigid, 

 collecting humus into which the roots run, as the cup-leaves of Drynaria 

 do, shallowly lobed, about 20 cm. broad and more than as high; above 

 this a narrower part, about 40 cm. high and less than 10 cm. broad,
