 Philipp. (name only). Field, ei Gardn. Sert. Plant, t. 51. 



Hab. Luzon, Cuming, n. 217. — A very distinct species, though allied to 

 the preceding. It is much smaller, very slender and graceful in every part. 

 Pinna; approximate, only slightly dimidiate, the lower margin not forming 

 a straight line, hut a curve, with the convex side outwards : the veins are 

 free and distinct, and the principal one does not run parallel with and close 

 to the lower margin, as in the preceding, hut inclines upwards from its com- 

 mencement. Two outer veinlets next the apex often bear one sorus. The 

 figure in Messrs. Fielding and Gardner's ' Sertum Plantarum ' is very ac- 

 curate, and I should not have again given it here, but my plate was pre- 

 pared before their's was published. 



60. D.Par/ceri, Hook.; small flaccid, caudex short creep- 

 ing sending out long smooth fibrous radicles, fronds narrow- 

 lanceolate from a rather broad base, pinnae close membra- 

 naceous thin half oval broad and subfalcate (lower margin 

 incurved), u]iper margin unequally lobato-crenate with 3 — 5 

 lobes, principal vein not parallel with the lower margin but 

 slightly diverging and bearing 3 — 4 simple or forked veins, 

 involucres small subreniform at the base of the lobules some- 

 times confluent (2 veinlets bearing 1 sorus), stipes and rachis 

 filiform dark coloured. (Tab. LI II. C.) 



Hab. British Guiana, C. S. Parhcr. — Quite different from the two pre- 

 ceding. Fronds very flaccid and thin, shorter and broader than the last, 

 especially at the base, with very differently formed pinnae, and dark-colored 

 stipes and rachis. 



61. D. licjiiiptera, Bory; "caudex creeping slender scaly, 

 fronds linear pinnate, pinna; alternate dimidiate pinnatifid 

 above, segments bifid." Bory in Belanger Voy. Bot. p. 75, 

 t. 7,f. 2. Saccoloma ? hemipterum, Pr. Davallia digitata, 

 Kaulf. Herb, (according to Pre.slJ. 



Hab. On the trunks of trees, forests of Java, Belanger. — To judge from 

 the figure and description, this has the habit of D. Bori/ana, with the same 

 scandent caudex and similarly shaped pinuEe; but the whole plant is small- 

 er and the upper side of the pinnae is cut almost to the base into narrow 

 linear, entire or bifid segments: the fructification is unknown, so that the 

 very genus must be doubtful. 



62. D. adiantifolia, Hook. ; " frond pinnate membranace- 

 ous glabrous, pinnae (numerous small) subsessile trapezoid 

 obtuse crenate on the superior margin, sori submarginal so- 

 litary, stipes and rachis glabrous." Aspidium adiantoides, 

 Bl. En. Fil. Jav. p. 145. Saccoloma adiantoides, Pr. 



Hab. Trees, Moluccas, Bhime. — With this I am unacquainted. Presl 

 refers it to Saccoloma ; but the above is all the description that is given of it. 

 Dubious species probably of this group. 



63. D. ? cuneifolia, Hook. — Saccoloma cuneifolium, Presl, 

 Tent. Pterid. p. 126, name only.
