CHARACTERS OF TRIBES AED GENERA, 189 
54.—CHEIROPLEURIA. Pr. (1849). 
Acrostichum, sp. Hook. Sp. Fil, 
Vernation sarmentose. Fronds distant or contiguous, 13 or 
more feet in length, long stipate, flabellately 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. Acrostichum bicuspe, Hook. 
Illust. Hook. Sp. Fil. 5, t. 304. 
Oss.—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. 198, t. 7 and 8; C. tricuspe (Hook.). : 
Sikkim, Java, and other Malayan islands. 
Ons.—It is probable that the above three species are 
different forms of one only. 
Sect. 9.— ARTHROBOTEE. 
Vernation sarmentose. Fronds pinnate or bipinnate, 
segments articulated with the rachis. Veins free or an- 
gularly anastomosing. 
* Veins free. 
55.—Lomariorsis, Fée (1844). 
Polybotrya sp., auct.; Acrostichwm sp., Hook. Sp. Fil. 
. Vernation uniserial; sarmentum scandent. Fronds pin- 
nate, 1 to 3 feet high; pinne linear, elliptical, broad 
lanceolate, acuminate, 2 to 10 inches long, articulate ` 
with the rachis. Veins uniform, simple, or forked, direct, `
