 Tsus Siina, Gulf of Corca, Jl'it/ord, n. I'M. — A species which cannot easily he 

 mistaken for any other if the short and singularly divergent or patenti-recurved 

 ultimate segments he considered, with the sori covering the whole segment, 

 and the involucre so open as quite to look like a cup, and giving the idea of a 

 dareoid species of DavaUia, with wliich genus other Darect have no slight 

 affinity. 



208. A. (Euasplenium) dimorphum, Kze. ; caudex " creep- 

 ing thick," stipites 6-12 inches and more long, fronds ample 

 2 feet and more long chartaceo-menibranaceous dcltoideo- 

 ovate a foot and more broad tripinnate, sterile and fertile 

 ditVerent on the same or on different plants, pinnte j)ctiolate 

 ))riuiary sterile ones horizontal broad-oblong or ovato-lan- 

 ccolate 5-G inches long again pinnate, secondary pinnse pe- 

 tiolate rhom])oidly ovate unequally cuneate at the base ser- 

 rated and sublaciniated, inferior ones lobed in their lower 

 half, lowest superior one pinnate below, pinnules cuneate 

 serrated at the apex, fertile pinnae numerous terminal often 

 abruptly so, sometimes the broad sterile pinntc have the ser- 

 ratures ajid lobes gradually becoming laciniated and fertile, 

 in the perfectly fructified state all are deeply pinnatifid 

 with narrow linear obtuse or acute segments patent or some- 

 times recurved not exceeding { an inch in length, veins 

 central forking with the segments, sori linear solitary upon 

 the segments or sometimes double one on each side the 

 vein firm of nearly the same colour as the frond. — Kze. in

Hab. Norfolk Island, and nowhere else, as far as yet known. — This fine Fern, 

 like the well-known Osmunda regalis, has the sterile pinnae and the fertile ones 

 quite different in form and composition, sometimes on the same plant (and then 

 forming the upper portion) ; sometimes the two kinds are distinct. 



209. A. (Euasplenium) A'ovce-Caledonice, Hook.; stipes in 

 my solitary specimen a foot long, frond (dimorphous?), fer- 

 tile a span long and as much broad subrotundo-deltoid co- 

 riaceous pale whitish very laxly and irregularly tripinnate, 

 primary and secondary pinna; long-petioled dichotomously 

 divided ultimate pinnules all fertile linear-elongate rostrate 

 (generally contracted above the sorus), veining very indis-
