Hab. China, Osbeck, Becchey. Isle of Bonin {Herb. Avt. Petiop.) 

 Philippine Isles ? Cavanillcs. Java, Blume P — I was disposed to consider 

 this a variety of D. tenuifolia, Sw., receiving it, as I have done, from China 

 (but from China alone) in company with thai species: still, a further exami- 

 nation of specimens leads me to the conclusion that it is truly distinct ; 

 and though a rude, yet the figure in Osbeck is a faithful representation of 

 the species. It is generally much smaller than Z>. tenuifolia, and the 

 stipes considerably shorter in proportion, the texture is far thicker, more 

 coriaceous, and one could suppose it to be almost fleshy when recent ; 

 the pinnules are much broader, not truly cuneate, but obovato-cuneate; 

 that is, the angles arc rounded off and the apex is quite entire. The 

 colour, when diy, is even of a darker brown, at least above, for the under- 

 side is almost always ferruginous : and the veins are sunk and obsolete, 

 of course, more copious in proportion to the breadth. I am uncertain 

 as to Blume's D. ferrugima, and am rather disposed, judging from his 

 figure, to refer to a somewhat broader state of D. teiiuifolia, our var. /3. 

 Of D. Chusana I am doubtful also. 



84. D. clavata, Sw. ; eaudex creeping lanate with dark 

 brown articulated hairs, stipes erect elongated pale straw- 

 colour, frond erect ovato-lanceolate rather short lax submem- 

 branaceous tripinnatc, the segments or pinnules distant ulti- 

 mate ones very narrow linear-cuneate simple or forked 

 glabrous, the apex sharply inciso-dentate, rachis com]iressed 

 slightly winged, involucre terminal subrotund transverse often 

 erose. — .SVr. Syn. Fil. p. 133. Jl'illd. Sp. PI. v. p. 47S.
