 ones branching and becoming lost before they quite reach the edge, including 

 irregular rather large areolae with a few free veinlets ; sori in a very irregular 

 row between each main vein, often confluent. Hk. Sp. 5. p. 73. Colysis, Presl.

Hab. Panama, Seemann, 995. Differs from Phymatodes by its regular pinnated veins, 

 and from GoniophkUum by being without free veins, and by its dorsal sori.

 tortuose, nearly naked ; barren fr. sessile, 3-4 in. 1., 1 in. br., elliptical, narrowed 

 at both ends, with blunt lobes, which reach nearly halfway down ; fertile fr. 

 4-6 in. 1., 2-4 lin. br., short-stalked, entire ; texture papyraceous ; both sides

 black, subulate, deciduous ; st. distant, 3-4 in. 1., firm, erect, naked ; fr. 6-9 in. 

 each way, cordate-hastate, the apex acuminate, the lateral lobes rounded or 

 acute, the basal lobes deep, sometimes imbricated, the edge not toothed ; texture

 bright-ferruginous ; st. 2-4 in. ]., firm, erect, glossy ; fr. 4-6 in. L, simple, lan-
