1^2 XEPHRODICIVr, § EtINEPITRODIUM. 



Ilah. Sikkini-Tlimalaya, clev. I2,0n0 feet, Ilooke?- Jil. and Thomston. Assam, 

 Simons. Ilakniladi, Japan, C. Wrif/hf. — A most distinct species, with the sterile 

 pinnae exactly as in 0. Germanica, but extremely ditterent in the form and size of 

 the fertile ones, not in the least terete or tornlose, but remarkably flattened ; and 

 with the rcflexedor rather refracted margin glossy and membranaceous. Some of 

 the fertile pinnaj are 4 inches long, and, when the scariose margin is, in age, spread 

 open, with its lacerated edge, ,\ an inch wide. Neither in the old nor young (dried) 

 state ,of the plant have I found the trace of a proper involucre. Still I cannot 

 hesitate about placing the plant in its present genus. — The three species have a 

 strong natural affinity with each, but with no other Ferns. 



At p. 70, after Nephrodmm strpellafum, the following species should have 

 been jjlaced :- — 



16*. N. (Eunephrodium) refractum, Hook.; caudex erect, 

 stipites \h foot and more long angular glossy perfectly gla- 

 brous (as is the whole plant), fronds 15 inches long subco- 

 riaceo-membranaceous subpellucid glossy above hastato-ovate 

 acuminate pinnated (pinnatifid at the apex), pinnae 4-5 

 inches long \ an inch broad horizontally patent the lower 

 ones the longest and singularly deflexed especially the lowest 

 pair, all of them oblong-lanceolate acuminate the margin 

 lobato-pinnatifid their base unequal, the lower pinucC espe- 

 cially cut off as it were at the inferior base, bearing an 

 auricle above appressed to the rachis, veinlets about five pairs 

 all of them united each bearing a purplish sorus in the 

 middle over the whole frond, involucre small cordate dark- 

 purple. (Tab. CCLII.) — Polypodium refractum, Fisch. et

Hab. " Brazil." — I was wholly unacquainted with this most distinct Fern till after 

 the printing of the preceding pages of Aspidiece, and my attention is now di- 

 rected to it in the stove of the Royal Gardens, bearing unmistakable fructifica- 

 tion of Eunephrodium, though no author appears to have described the presence of 

 an involucre. The form as well as the texture of the frond, with the singularly 

 refracted and elongated lower pinnpe, are very peculiar. The fructifications are 

 placed with great regularity in the middle of each veinlet over the entire frond, 

 forming a series of inverted V's, corresponding with every lobule of the margin 

 of the frond. The species ap])ears to be unknown to authors except as a garden 

 plant, introduced, it would appear, by Dr. Fischer, from Brazil. Distinct as it is 

 from any known Eunephrodium, it has its analogue in our Nephrod. (Lnstrea) 

 macrotis, p. 86 of this volume, Tab. CCXLII. B, from Peru ; but, besides the dif- 

 ferent venation, N. macrotis is a much larger plant, with much longer auricles, 

 and the rachis, and costa?, and involucres, are very hairy; the inferior pinna; are 

 similarly refracted. Mrs. Walker informs me that this species bears bulbils in her 

 Fernerv at Enfield.
