Ilah. Jamaica, Sloane. Venezuela, Wagener, Fendler, n. 498. — A very liand- 

 some, and, as far as my observation goes, a rare species, which Mettciiius unites, 

 I scarcely think correctly, with Aspl. Rwmerianum. 



260. A. (Eudiplazium) Ropmerianum, Kze. ; stipes erect 

 often very stout 1-2 feet long, frond ample menil)ranaceous as 

 long as or longer than the stipes impari-pinnate all pctiolate 

 distant numerous 15-17 5 inches to a span and more lung 

 broad-oblong lanceolate finely acuminate ratlier obscurely 

 crenato-serrate towards the apex the rest sul)sinuate the ob- 

 tusely or subequally cuneate terminal pinna long-petiolate 

 very large often with two large auricles at the base, veins very 

 distinct horizontally spreading often recurvo-falcate twice 

 forked representing fine black lines, sori linear-elongate aris- 

 ing from the superior veinlet and generally extending from 

 near the rachis to the margin, those of the terminal pinna 

 not unfrequently diplazioid. — Kze. in Linncea, ix. p. 62. Met-

Ilab. Peru, Pceppig, in Herb. Noitlr. Tarapota, Eastern Peru, Spruce, n.4G74. 

 Antioquia, Jervoise. Jamaica, Bancroft. Cuba, Linden, n. 1891). — This has a 

 great resemblance to some states of what I consider Diplazium juylandifolium, 

 Sw., of my ' Filices Exoticac,' t. 100 ; so much so, that the careful Mettenius has 

 considered it a var. of A. Rcemei-ianum. Of this latter species he justly observes 

 of the veins, that the terminal pinna bears diplazioid sori, all the lateral pinnae 

 bear asplenioid ones, whereas in our Aspl. (Diplazium) juylandifolium all the 

 sori are diplazioid, and further, they have less acuminated and more entire and 

 sessile pinna;. 



261. A. (Eudiplazium) Ottonis, Kl. ; "frond pinnate ob- 

 long acuminate, pinnae lanceolate acuminate membranaceous 

 distant very patent petiolate sessile towards the apex then 

 confluent slightly serrated lower ones inciso-serrate obtuse at 

 the base incisures o])liquely acute, upwards obsoletely dentato- 

 serrate, stipites deciduously paleaceous and as well as the 

 rachis tawny compressed glabrous beneath." Diplazium, A7. 

 in Limicea, xx. p. 360. Metten. Asplen. p. 180. Asplen, 

 rhoii'olium, Metten. A.yi/en. p. 1 78. — Var. /3 ? ; margins of the 

 pinnae pinnatifid, lobes sliort broad subfalcate.
