Genus 14. DEPARIA Hook, et Grev. 



1. D. prolifera, Hook. A plant lent to us by Sir F. Mueller, from 

 Illawarra, New South Wales, will probably prove to be 

 specifically distinct from the Hawaian type. It has narrow 

 segments, and smaller less exserted sori. I believe that only a 

 single specimen has been seen. 



3. D. Godefroyi, Luerss., in Fil. Graef. 222, T. 19 (under Denn- 

 s/aedh'a). Fiji Isles, Graeffe, 54. Habit and cutting of Nephro- 

 dium cicutarium ; veins forming copious areolae with branched 

 free included veinlets. 



Genus 14*. LECANOPTERIS Blume. 



I now think this will have to stand as a distinct genus in the 

 neighbourhood of Dtcksom'a, from which it differs by having the in- 

 dusium formed from a single valve, and curious tuberous rootstock, 

 with species as follows, viz. : 



1. L. carnosa, Blume, Fil. Jav. tab. 94 A. Perak and Philippine and 



Malay Isles. 



2. L. pumila, Blume, Fil. Jav. tab. 94 B. Malay Isles. 



3. L. Macleayii, Baker, n. sp. Rootstock not seen. Stipe short, 



naked. Frond lanceolate, glabrous, moderately firm, above a 

 foot long, 4-5 in. broad, cut down to a narrowly-winged 

 rachis with many linear obtuse crenate pinnae, | in. broad. 

 Sori distant, many to a pinnae ; indusium very small, orbicular, 

 convex. Java, Macleay. 



4. L. Curtisii, Baker, in Hook. Icones, tab. 1607. Sumatra, 



Curtis. 



5. L. deparioides, Baker, in Journ. Bot. 1881, 366. Davalliadepa- 



rioides, Cesati, Fil. Becc. Born. 13, tab. 4, fig. 8. Rootstock 

 tuberous, as in the other species, produced into short phyllo- 

 podes articulated at the top. Stipe naked, substramineous, 6-8 in. 

 long. Frond lanceolate, membranous, glabrous, simply pinnate, 

 i \-2 ft. long, 3-4 in. broad ; rachis winged only at the top ; 

 pinnae sessile, linear, obtuse, in. broad, narrowed towards 

 the base ; barren entire ; fertile crenate, with a sorus at the tip 

 of each lobe. Venation of Phymatodes. Indusium as in the other 

 species, consisting of a cup, formed from the edge of the frond, 

 holding a small globose sorus. Borneo, Sarawak, Beccari.
