iioatb, ihe adult ones naked, younger ones and raeliis densely 

 clothed with lenuginous scales and down. — Br. Prodr.p. 161. 

 Hook, et Grev. Ic. Fil. t. 58. Calymella, Presl. 



Hab. Tasmania. Abundant on Mount Wellin<i^ton, and on the western 

 mountains, Broun, R. Gunn, Es(j. — A small species, readily distinguished 

 by its elosely jdaeed orbicular or semiglobose segments, the younger 

 shoots densely clothed with rusty-coloured tomentum mixed with scales. 



4. G. po/i/podioides, Sm. ; fronds dichotomous, branches 

 pinnate, pinna) jnnnatifid, segments ovate glaucous beneath, 

 caj)sules 3 — 4 immersed forming a flat-topped sorus. — Sm. 

 Act. Taur. v. p. 4 J 9, and ix. / 10. Schk. Fil. t. 149.—^. 

 fronds more glaucous beneath. G. glauca, Sw. (not Mer- 

 tensia glauca, Sw.) G. gigantea, Kaulf. 



Hab. S. Africa, probably chiefly on tlie mountains near the Cape Colo- 

 ny : at an elevation of from 1300 to 4500 feet, {Drege, Eklon and Zeyher). 

 — The younger fronds, and especially the partial and main rachis, are fre- 

 quently clothed with rusty down. Tlie sorus is a beautiful object, sunk 

 in a circular depression, which the three or four capsules exactly fil], de- 

 pressed at the top, and marked from the centre with radiated lines, formed 

 by the close proximity of the capsules and their bursting in the middle, 

 from the centre to the circumference. 



5. G. micropJiylla, Br. ; fronds dichotomous divaricated, 

 branches pinnate, pinna) pinnatifid glabrous, segments ovate 

 or subrotund nearly ])laue, their margins slightly recurved, 

 capsules 3 — 4 exserted lax, branches and rachis clothed with 

 ferruginous chafly hairs. — Br. Prodr.p. 161. G. Speluncae, 

 Guillem. Ic. Plant. Aiistr. Par. t. 12. G. circinata ? Sw. 



Hab. Port Jackson, Brown. Tasmania, Brown, R. Gunn, Esq. — If I do 

 not mistake this plant, the segments of the leaves are ovate as well as sub- 

 rotund, and it is distinguished from the following by the simply and slight- 

 ly recurved margins of the segments, so that the sori are more exposed to 

 view. 



6. G.dicarpa, Br.; fronds dichotomous divaricated, branches 

 pinnate, pinna) pinnatifid, segments orbicular very fornicate 

 with a broad recurved margin, capsules 2 within the hollow 

 of the segment, branches nearly glabrous, rachis hairy. (Tab. 

 I. C.) — Br. Prodr. p. 261. G. microphylla, Sieb. Fl. Mi.vf. 

 n. 230. 



Hab. Tasmania, Brown, R. Gunn, Esq. — This species is easily recog- 

 nized by the orbicular and almost saccate fomi of the segments. 



7. G. setnivestita, Labill. ; fi-onds dichotomous divaricated, 

 branches pectinate, piruue pinnatifid, segments orbicular ovate 

 slightly concave, branches densely ferruginco-pubescent, ra- 

 chis with few stellated hairs, capsules (3 — 4 exserted, Labill.) 

 (Tab. II. A.)— Labill. Serf. Nov. Caled. p. 8, /. 11. 



Hab. New Caledonia, Labillardiire. Malacca, Cuminy. — In many re- 

 spects agreeing with some states of G. microp/u/lla : and the slight differ-
