CHAEACTEES OF TRIBES AED GENERA. 139 



64. — Cheiropleuria. Pr. (1849). 

 Acrostichum, sp. Hook. Sp. Fil. 



VernafioH sarmentose. Frottds distant or contiguous, I5 or 

 more feet in length, long stipate, flabollately bi-tripartite, 

 firm, coriaceous. Main veins, two to three, radiating from 

 the base, venules compoundly anastomosing. Fertile fronds 

 wholly, or the central lobes only, sporangiferous. 



Type. Aeroslichum. hicuspe, Hook. 



Illust. Hook. Sp. Fil. 5, t. 301. 



Obs. — This genus consists of two species, which in 

 venation agree with Gymnopteris, but differ so much in 

 aspect and texture that I deem it best to follow Presl in 

 viewing them as a distinct genus. 



Sp. C. bicuspis {Hook.) ; C. vespertilio {Hook.), Lond. 

 Journ. Bot., p. 193, t. 7 and 8 ; C. tricuspe {Hook.). 



Sikkim, Java, and other Malayan islands. 



Obs. — It is probable that the above three species are 

 different forms of one only. 



Sect. 3. — Aethkobote^. 

 Vernation sarmentose. Fronds pinnate or bipinnate, 

 segments articulated with the rachis. Veins free or an- 

 gularly anastomosing. 



* Veins free. 



55.- — LoMARiOFSis, Fee (1811). 



Polyhotrya sp., auct. ; Acro.dichmn sp., Hook. Sji. Fil. 



Vernation uniserial ; sarmentnm scandent. Fronds pin- 

 nate, 1 to 3 feet high ; pinnre linear, elliptical, broad 

 lanceolate, acuminate, 2 to 10 inches long, articulate 

 with the rachis. Veins uniform, simple, or forked, direct.
