Hal). Columbia, Iloritz, n. 256 (A7.). Venezuela, Fendler,n. 244 (Polyp, lasio- 

 pus, KL, Eat. in Herb, nostr.) — It is to be regretted tliat neitber of tbe authors 

 who have given a specific character of tliis obscure plant makes any allusion to 

 its affinities. I have no authentic specimens, unless those of Fendler, named by 

 Eaton, may be considered such ; and here thej-e are two forms, one pubescent and 

 •with an opaque frond, the other with a pellucid frond and clearly a free black 

 venation. The affinity is close with some of the small abnormal forms of P. 

 loriceum and its allies.

262. P. (Goniophlebium) transhicens, Kze. ; caudex stout 

 (thick as one's httle finger) creeping fusco-paleaceous, stipes 

 testaceous brown 4 inches long, fronds firm-membranaceous 

 translucent pale-green 8-10 inches long 6-9 inches broad gla- 

 brous deltoid acuminate deeply nearly to the rachis pinnatifid, 

 segments 7-17 lanceolate horizontal decurrent at the base, 

 lower ones sometimes free, terminal one elongated, all of 

 them coarsely and unequally serrato-dentatc obtusely acumi- 

 nate, veins black (when the frond is held up to the light) 

 anastomosing and forming a costal series of large soriferous 

 areoles, veinlets free, sori rather small distant. — Kze. in

Hab. Juan Fernandez, Bartero, Cuming, n. 1333, Douglas. — ^A very peculiar 

 species, well defined by Kunze. It appears to be peculiar to the island of Juan 

 Fernandez, and all my specimens, from three different collectors, are very nni- 

 form. The segments are large, some of them nearly 5 inches long, and eroso- 

 dentate. 



263. P. (Goniophlebium) trilobuin, Cav. ; caudex long 

 creeping stout l^ranched squarrose with copious ferruginous 

 scales, stipes testaceous 4-6 inches long, fronds 4-10 inches 

 long as much wide sul^coriaceous l)road-ovate in circumscrip- 

 tion deeply nearly to the rachis pinnatifid (or rather remotely 

 pinnate with the rachis winged), segments or pinnae obliquely 

 patent 3-9, terminal one (often tripartite) very much elon- 

 gated and sometimes also the lowest painoften 6 inches long 

 from :f-ij of an inch wide linear-lanceolate or ensiform more 

 or less acuminated, lowest pair sometimes bipartite, veins
