1. G. circinata (coiled or curled round), Swartx, Syn. Fillc. 166, 394 ; 

 Benth. Fl. Austr. vii. 697. Parasol Fern. Fronds sometimes short, but often. 

 repeatedly dichotdmous and scrambling to the height of many feet, the mam 

 rhachis glabrous or shortly scaly-hirsute. Pinnules numerous along the ultimate 

 branches, 1 to 2in. long, pinnately divided into numerous ovate or almost 

 orbicular segments, 1 to IJ lines diameter, adnata by the broad base, often 

 whitish underneath, flat or the margins more or less recurved or revolute. Sori 

 of 2 to 4 spore-cases, superficial or half immersed in a slight cavity near the 

 upper basal angle of the segments.— Hook, and Bak. Syn. Filic. 11 ; F. v. M. 

 Fragm. v. 115; G. spehmcm, R. Br. Prod. 160; Guillem. Ic. PI. Austral, t. 12 ;

Also in New Zealand, New Caledonia and the Malayan Archipelago and Peninsula. 



2. G. dicarpa (2-fruited), R. Br. Prod. 161; Benth. Fl. Austr. vii. 698. 

 Fronds of the smaller specimens of G. circinata, with the rhaohis glabrous or 

 scaly-hispid, but the segments, mostly under 1 line diameter, are almost globular 

 and bullate, the revolute margins almost closed over to to the rhachis. Sori 

 large in proportion, of 2 or rarely 3 spore-cases, in a broad cavity close to the 

 rhachis, occupying more than half the breadth of the segment. — Hook. Filio. 

 Exot. t. 40 ; Kunze, Farrenkr. t. 70, f. 2 ; Hook. f. Fl. Tasm. ii. 131 ; F. v. M. 

 Fragm. v. 115 ; Bail. Litho. Ferns Ql. 15. 



Hab.: Eookingham Bay, Dallachy ; Moreton Island and other southern localities. 

 The species is also in New Zealand, New Caledonia and the Malayan Archipelago. 



3. Cr. flabellata (fan-like), R. Br. Prod. 161 ; Benth. Fl. Austr. vii. 698. 

 Fronds repeatedly dichotomous, attaining 2 to 4ft. in height. Pinnules numerous 

 along the last branches and continued along the rhaohis below the last fork, 

 linear-lanceolate, entire or the margins obscurely undulate, rarely above lin. 

 long, dilated and sometimes confluent at the base, 1 to IJ lines broad, glabrous 

 or with a few scaly hairs underneath, the numerous veinlets proceeding from the 

 midrib forked, one fork bearing below the summit a superficial sorus of 2 to 5, 

 usually 3 or 4, spore-cases. — Hook. Spec. Filio. i. 6 ; Filio. Exot. t. 71 ; Hook, 

 and Bak. Syn. Filic. 12 ; Hook. fil. Fl. Tasm. ii. 181 ; F. v. M. Fragm. v. 114 ; 

 Bail. Litho. Ferns Ql. 16. 



Hab.: York Peninsula, N. Taylor ; Kookingham Bay, W. Hill, Dallachy ; Brisbane River, 

 Moreton Bay, F. v. Mueller. 



The species is also in New Zealand and New Caledonia. 



4. G. flagellaris (thong-hke), Spreng. ; Baker in Fl. of Mauritius and the 

 Seychelles. Fronds 8 or 4 times dichotomously forked, leafy from the first- 

 forking continuously to the top of the ultimate branohlets, the texture rigidly 

 subooriaoeous, the upper surface dark-green and naked, the lower glaucous and 

 with a little ferruginous down on the midrib of the segments. PinnsB lanceolate, 

 1 to 2in. broad, cut down to the rhachis into close adnate entire linear ultimate 

 segments. Veins fine, distinct, once forked near the base. Sori on the back of 

 the veins, nearer the edge than the midrib, consisting of not more than 4 or 

 5 capsules. — Bail. Litho. Ferns Ql. 18. 



Hab.: Messrs. Schneider and Tryon brought me, from the top" of the Macpherson Range, 

 sterile portions of a Gleichenia, which I think belonged to the above species. It is a fern of 

 wide range, having been gathered in New Guinea, Java, the Malay Islands, Fiji, Mauritius, 

 Bourbon, and Madagascar, and is considered to include G. lievigata, Willd. ; G. bifurcata, 

 Bltime. ; G. bracteatti, Blums. ; and <?. imtricata, Bojer.
