POLYPODIUM, § GONIOI'TERIS. 5 



Ilab. Caracas, Jfilld. ; Brazil, about Rio, very abundant ; island of St. Sebastian, 

 S. lat. 24°, Mr. Fox. — A most distinct and well-marked species. 



230. P. (Goniopteris) Sandwicense, Hook. ; " subarbores- 

 cent, caudex 1^ foot long erect," stipes 1^-2 feet long 

 "paleaceous at the base" fulvo-villous above and on the 

 rachis, fronds 2-3 feet long a foot and more wide coriaceo- 

 rnenibranaceous glabrous or pilosulous on the veins beneath 

 broad ovato-lanceolate moderately acuminated pinnated, pin- 

 nee numerous subdistaiit sessile or short-petioled 5-8 inches 

 long l-l 2 inch wide from a broad often sharply auricled base 

 elongato-oblong acuminated more or less falcate very coarsely 

 lobato-serrate the serratures acute or obtuse, terminal pinna 

 rather longer petioled, veinlets erecto-patent subdistant often 

 alternate 7-9 pairs all united (except in the teeth of the 

 margin), sori small subrotund or oblong generally on the 

 middle of the veinlet but forming 2 very irregular series. — 

 Stegnogramme, Brack. Fil. U. S. Expl. Exped.p. 26. t. 4./. 2. 



Hab. Sandwich Islands, near the crater of Kilauea, Brackenridye, Dr. Hille- 

 brand, n. 48. — The copious sori on my specimens are rarely elongated, cer- 

 tainly not at all a[)proaching to the quite linear fructifications of Stegnogramme 

 aspidioides, Bl., with which Brackenridge compares it, in which moreover the 

 upper pinniE of the fronds are gradually confluent into a deeply pinnatifid ape.x 

 (see our figure of that plant, Ic. Plant, t. 950, or Cent, of Ferns, t. 50). Its near- 

 est affinity is P. pennigerum, Forst. 



231. P. (Goniopteris) unitum. Hook. ; caudex ?, stipes " 1- 

 14 foot long stramineous glabrous," fronds 2^-3 feet long 

 8-12 inches wide broad-oblongo-lanceolate membranaceous 

 dark-green often gemmiferous pinnate, terminal pinna large 

 lanceolate lateral ones horizonal 4-6 inches long rather dis- 

 tant often exactly opposite from a broad truncated sul)auri- 

 cled sessile base oblong gradually and finely acuminated, 

 the margin lobato-pinnatifid, lobes rounded entire or sub- 

 denticulate, veinlets about 5-6 distant pairs of which the 3 

 or 4 lowest are connivent and bear the small sori close to 

 the base where they are subconfluent and then oblong, they 

 form 2-3 costular series distant from the margin. — Gym-

 p. 252. G. sylvatica, Pappe and Raivson, En. Fil. Cap.p.Si). 



Hab. Natal, Guemius. — A distinct and very remarkable species. 



232. P. (Goniopteris) reptans, Sw. ; caudex short small 

 erect often very paleaceous, stipites tufted stramineous slen- 

 der and as well as the rachis glabrous, fronds firm-meuibra-
