iVom uny previously described, with singularly thin, membranaceous pin- 

 nules, tlie sterile ones much more deeply lobed than the iertile ones. 



59. L. ohlusa, J. Sm. ; caudex creeping, sti}Des tetragonal 

 twice or thrice longer than the frond, frond pinnate broadly 

 ovate or siibdelloid, pinnae 4 — 5 oblong-lanceolate subcori- 

 aceo-mcnibranaccous firm reticulated, pinnules oblong some- 

 what 4-angled rarely subrecurvo-falcate apex very obtuse, su- 

 perior base truncate, the lower margin formed by the costa, 

 superior margin slightly lobed, sori broad interrupted. — Syna- 

 phlebium obtusum, ./. Sm. in Hook. Journ. Bat, p. 415, 

 {name on It/). 



Hal). Malacca, Cuming, n. 394. — Allied to the preceding, but different 

 in the much smaller size, firmer texture, dissimilar shape of the pinnules, 

 which, however, form almost an exact parallelogram in most instances 

 with 4 somewhat acute angles, copious and broad sori, interrupted indeed 

 but placed close together in consequence of the proximity of the lobes. 



60. L. davalloidesy Bl. ; caudex creeping, stipes and rachis 

 long tetragonous glabrous, stipites tufted, frond subdeltoid- 

 ovate bipinnate, pinnae erecto-patent lanceolate acuminate, 

 pinnides dimidiato-oblique membranaceous. reticulated (reti- 

 culations few) the apex obtuse, superior base truncate, costa 

 at the inferior margin, superior margin rather deeply but ir- 

 regularly lobed, sori interrupted linear confined to the apices 

 of the lobes. (Tab. LXVIII. A.)—BL En. Fil. Jav. p. 218.

 fructification of this plant, I was induced to refer it to Davallia, at page 

 177 of this work: but now that I find it is the L. lobata of Wallich, and that 

 I have recently received fine specimens from Java, gathered by Mr. Thos. 

 Lobb, I am happy to be able to restore it to its proper genus, Lindsma, 

 sect. Schizoloma {Gaud.), or vSynaphlebium (/. Sm.) It is a well-marked 

 and very handsome species, of a light green colour.

 inferior one may be considered accessory, uniting many 

 veins. — Tropical Fern. Rhizoma simple, thick. Fronds
