subundulateil, tlie sef^ments shorter, more spreading, narrower, not at all 

 palmate. The color is not so green ; the involucres are nmcb smaller, ne- 

 ver terminal on tlie longer segments, and not at all sunk. 



54. II. dila/afnm, S\v. ; tall erect, fronds ample ovate 

 acinninalL- or oblong tripinnalifid, primary divisions ovato- 

 lancenlate and as well as the secondary segments broad and 

 sub] )al mate below, the segments broad-linear elongated sub- 

 caudate and drooping entire, involucres terminal on the seg- 

 ments orbicular lower half cuneatc sunk in the frond and 

 broader than the segments, the valves slightly convex semi- 

 orbicular very ol)tuse entire, recejitacles clavate included, 

 stipes ancipiti-alate decurrent almost to the base and as well 

 as the rachis green. — Sw. Syn. Fil. p. 149 and 373. Schkh.

Hal>. New Zealand, Forster and othfir travellers. Rocks and trunks of 

 trees, woods of Java, Blume. — A very handsome species, well represented 

 in the ' Icones Filicnm,' except that in most specimens the bases of the seg-

 ways of the same pale hue as the frond, which is often a foot or even a foot 

 and a half high. 



55. H. p}-olrit.<}H7n, Hook. ; fronds pendent oblong-acumi- 

 nate bi-trij^innatifid flaccid compact, primary divisions ovate 

 aruminate, segments linear obtuse entire, involucres terminal 

 small obovate obtuse the lower half cuneate and siuik, the 

 valves entire, receptacles in age thrice as long as the involu-

Ilab. Re.ilcjo, Central America, Sincltir. Jamaica; woods above Mount 

 Stcwirt, Purdie. — Stipes 2 — 3 inches long; fronds about 5 inches, mem- 

 bianaceous. Involucres equal in breadth to the segments, half sunk, the 

 upper half 2-valved and about one-third or one-fourth the length of the old 

 receptacle. Well distinguished by the small size of the involucre, and in 

 jigc by the exserted receptacle. 



56. H. recnirvum, Gaud. ; fronds bipinnatifid flaccid pen- 

 dent oblong acuminate, primary divisions elongate recurved 

 or erecto-])atcnt dichotomously pinnatifid lower ones distant, 

 the segments simple elongated linear entire, involucres su- 

 ])raaxillary solitary terminal sessile or subsessile (the base 

 inmiersed and cuneate) oval or subrotund 2-valved nearly to 

 the base compressed slightly serrated rarely entire. (Tab.
