and concealed in the texture of the frond. Fertile fronds usually smaller and 

 more obtuse.— F. v. M. Fragm. v. 138; Bail. Litho. Ferns, Ql. 178; 

 Eiaphoglossum confonne, Sehott ; Bail. Ql. Ferns, 9.

Widely spread over the tropical and southern extratropioal regions of the New and the Old 

 World. 



2. A. scandens (climbing), J. Sm.; Hook. Spec. Filic. v. 249, Syn. Filic. 

 412 ; Benth. Fl. Austr. vii. 778. Ehizome woody, scaleless, creeping in 

 swamps or climbin? on trees. Fronds 1 to 3ft. long, simply pinnate. Pinnae of 

 the barren fronds broadly lanceolate, acuminate, rounded or cuneate at the base 

 and shortly petiolate, 3 to Sin. long, f to l^in. broad, entire or slightly dentate, 

 coriaceous, smooth and shining. Veins very numerous fine and closely parallel, 

 Pinnse of the fertile fronds long and very narrow-linear, sometimes almost 

 terete, sometimes fiat and 2 lines broad. — F. v. M. Fragm. vi. 124 ; Bail. Litho. 

 Ferns Ql. 179 ; Stenochlana scandens, J. Sm.; Bail, Ql. Ferns, 10.

3. A., sorbifolium (Sorbus-leaved), Linn.; Hook. Spec. Filic. v. 241, Syn. 

 Filic. 412, var. leptocarpum, Benth. Fl. Austr. vii. 779. Rhizome woody, often 

 climbing trees to the height of 30 or 40ft. Fronds pinnate, 1 to 2ft. long. 

 Pinnse of the barren fronds lanceolate, acuminate, equally or obliquely tapering 

 into a short petiole, 3 to Sin. long, 4 to 8 lines broad, often denticulate, not very 

 thick but smooth and shining. Veins numerous, parallel, f to 1 line apart. 

 Pinnae of the barren fronds more numerous, almost filiform, Jin. or more broad.

 Lomariopsis Brightia, F. v. M. in Bail. Ql. Ferns, 10. 



Hab.: Eockingham Bay and other tropical localities. Common also in the south. 



Spread over the tropical regions of the New and the Old World. Exceedingly variable as to 

 the breadth of the fertile pinnie, etc., and divided by F6e into seventeen species of a genus 

 Lomariopsis, amongst which his L. leptocarpa and some others are well represented amongst 

 Dallaohy's specimens collected at Eockingham B&j.— Benth. 



4. iL. repandum (repand), Blume; Hook. Spec. Filic. v. 260; Syn. Filic. 



419 ; Benth, Fl. Austr. vii. 779. Rhizome creeping. Fronds 1 to 2ft. long, 



pinnate, the rhachis scaly. Pinnse of the barren fronds membranous, lanceolate, 



the lower ones obliquely truncate at the base and attached by the midrib, 3 to 



5in. long, often under lin. broad, pinnatifid with broad lobes rarely reaching 



halfway to the midrib, the upper pinnae smaller more entire and confluent into 



a broad wing to the rhachis. Veins copiously reticulate, with a central vein 



opposite each lobe, one of the veins often produced into a seta in the 



sinus. Pinnae of -the fertile fronds much smaller and narrower, but usually 



more or less pinnately lobed or broadly crenate. — F. v. M. Fragm. v. 138 ; 



Bail. Litho. Ferns Ql. 181, 182. 



Hab.: Tropical scrubs. Common. 



Extends over the Malayan Archipelago to South China and the Pacific Islands. 



5. A. Taylori (after Dr. Norman Taylor), Bail'., in Rip. of QL. Accli, Soc, 

 April, 1884. Fronds scaly, somewhat tufted from a short, creeping, knotted 

 rhizome, stipitesof fertile fronds from under 2in. to 51n. long, slender, those of the 

 sterile fronds usually shorter ; fronds pinnate in the lower, pinnatifid in the upper 

 part, and usually terminating in a narrow, tail-like, proliferous apex ; pinnae 

 obtuse-oblong, very irregularly lobed, 1 to Sin. long, 3 to 9 lines broad. Veins 

 forming a row of long costular areoles, the rest free to the margin, where one 

 often is produced into a seta in the sinus. — Bail. Litho. Ferns Ql. 183-4. 



Hab.: On wet rocks, Johnstone Eiver. 



Very near A. repandum, Bl., but a much smaller plant with a closer habit. Beferred to by 

 Bentham in Fl. Austr. vii. 779.
