llab. Tukonosima, Japan, C. IJ'rir/ht, J/erb. of the U.S. North Pacific Explor. 

 Exped. under Commodores Ringgold and Rodgers, 1853-1856. — This is a very fine 

 species, and very distinct from any Aspleninm known, but evidently belonging to 

 the S(dicifoUum-^\o\\\>, and perhaps most nearly allied to the species J. salicifo- 

 Hum itself. It is extremely ditterent from that, however, in the much-lobed 

 margins of the pinnae, in the large obovate anricle at the superior base, in the 

 long, falcate, and very acuminated apex, where the lobes are reduced to large serra- 

 tures. As it was sent to me by Dr. Asa Gray (among many other rare Japanese 

 plants) without any name, I bad proposed to dedicate it to D. C. Eaton, Esq., of 

 Newhavcn, Connecticut, the very able American Pteridologist, w ho is preparing a 

 notice of all the Ferns of this scientific Exploring Exi)cdition ; but that gentleman 

 considers that its discoverer has a stronger claim to the compliment. 



65. A. (E\ia.s\-)\emum) zainioides, Hook. ; stipes and rachis 

 deciduously scaly compressed and sulcated, frond a foot and 

 more long oblong-acuminate firm coriaceo-membranaceous 

 opaque (probably very succulent when fresh) impari-pinnate, 

 ])innce 14-lG or 1/ horizontally patent dimidiato-ovatc some- 

 times subfalcate obtuse or obtusely acuminate 27^ to 3 inches 

 long quite entire the base obliquely cuneate and tapering 

 into a very short petiole superior extended sometimes form- 

 ing an obtuse angle or imperfect auricle, terminal pinna the 

 largest elliptical- ovate with a more or less distinct lobe on 

 one side, veins sunk subflabellate especially near the base 

 erecto-patent twice or more forked distant, costa indistinct, 

 sori elongated almost parallel with the obscure costa often 

 interrupted sometimes an inch long and extending to the 

 margin, costa stout compressed. (Tab. CLXX.) 



Ilab. Isle of Penang, Dr. fiance.— "^o Fern that I am acquainted with 

 merits a name implying a resemblance to the leaves of a Zamia more than the 

 present. I believe the A. zamiaf'olium of Wilhienow is merged into A. dimidia- 

 tum, Sw'., and that of Presl he has himself changed to Tarachia Hmnkeana. In 

 case others should think ditferently of ihcse changes, I trust the name A. 

 zamioides will not be deemed objectionable. It is a very distinct species, and not 

 liable to be confounded with any other, but has some characters in common witii 

 the /'fl/ffl/Mwi-group, having affinity with Aspl. macrophyllum : but here the 

 pinnae are quite entire, and the venation is very ditterent. 



G6. A. (Euasplenium) sanffuinolenti/yn, Kze.; "petiole 6 

 inches long livid-brown, frond subcoriaceous ojiaque-green 

 eventually glabrous 7 inches to a foot long oblong a little 

 attenuated at the base acuminated impari-pinnate, pinnae 

 6-12 pairs obliquely patent petiolate 2^-3^ inches long, 

 from an inferior cuneate base superior broader obliquely or 

 exciso-truncate auriculate or subauriculate ovato-lanceolate
