while in Enterosora they are immersed in slit-like linear aperatures and 

 are mucli longer, but extrude eventually. In both this and Enterosora the 

 venation is connected, forming a series of two or three meshes on each 

 side of the midrib, while in P. trifurcatum the branches are uniformly en- 

 tirely free. The venation quite conforms to some of tbe states of 

 Phymatodes, the costal series being narrow and unoccupied by either free 

 branches or sori. Mr. Wm. Harris, F.L.S.. the Superintendent of the Hill 

 Gardens, the discoverer of it, whose name it bears, writes me that : " It 

 is almost as rare as Enterosora, and like that plant, it grows on the high 

 limbs of large forest trees, so that it is a difficult matter to detect it from 

 the ground, and when detected, it is an exceedingly difficult matter to get 

 within reach of it." Possibly this exalted elevation on large trees, almost 

 beyond reach of sight, may be the reason, more than their rareness, of the 

 late discovery of Enterosora in Jamaica.

 other parts glabrous an glossy; substance coriaceous and brittle: midrib and 

 veins on both sides covered in the parenchyma : surface wrinkled and striated 

 more especially the upper ; veins in groups, the lateral branches connected form-

 in part three, on each side, one to each mesh, on a shorter nr longer spur arising 

 from the niddle of the ;irch, generally medial but occasionally terminal : sunk in
