]22 ONYCHIUM. 



iDches to a foot and more long and as well as the rachises 

 pale brown or stramineous, frond a foot and more long ovato- 

 acuminate meuibranacco-coriaceous glossy 3 — 4 times pin- 

 natisected (primary and secondary divisions pinnated) seg- 

 ments uniform or nearly so in the sterile and fertile ones, all 

 narrow linear a little tapering below ultimate ones moderately 

 long all gradually acuminated (not mucronate even in the 

 fei'tile ones), sori oblong short occupying nearly the whole of 

 the back of the segments, involucres white or cream-colour 

 membranaceous meeting at the back, Spreng. Syst. Veyet.

 specimens of this plant, there is a preat resemblance to those of the preced- 

 ing {O. auratum), but the fronds, though varying much in size, are generally 

 broader in proportion to their length, with commonly more spreading jun- 

 nae and the ultimate segments more entire. In fructification the difftren- 

 ces are very apparent: the sori being formed on the unchanged segments, 

 they are consequently very small in comparison, short, oblong, and of a 

 pale white or cream-colour, never golden coloured. The Cheilanthes con- 

 tigua of Dr. Wallich has the fronds a little broader and the segments nar- 

 rower, and they form no permanent or tangible variety. 



Kaulfuss' representation of a fertile portion of the frond of his Onychiiim 

 Capense (O. Japonicum, Kze., our next species) is a faithful representation 

 of our plant.

Hab. Japan, in Kosido, Satsuma, Nagasaki and elsewhere, in mountain 

 districts, Thunberg. — " Frond a foot and a half and more long, weak, flex- 

 uose, decompound, above triplicato-pinnate, the apex subcaudate. Branches 

 very remote, slender, triplicato-piunale, pinnules dentato-laciniate, the seg- 

 ments oblong acute bearing the fructilicatiou. Sori inserted at the margin 

 of the laciniffi under the apex in the sinus of the indusium. Indusia sub- 

 marginal, membranaceous, white, connivent (limbis connivcntia), at length 

 opening with a longitudinal suture." — With this species I am unacquaint- 

 ed, except from the description, and from the figure of Kaulfuss, which 

 shows an apex of a branch, which, as already observed under O. lucidum, 

 seems in no way diflerent from that plant. SchleLhlendal,iii his 'Adumbr.
