150 FLORA OF TASMANIA. [ Filices. 
Oss. Amongst Gunn's specimens of this plant and Hypolepis tenuifolia, I find specimens of Hyp. tenuifolia, 
Hook. (a New Zealand species), which I regret having overlooked previously. It may be known by its small size 
and simply bipinnate fronds, and is perhaps only a small state of H. tenuifolia. Mr. Gunn's specimens are from 
the cataracts of the South Esk River and Western Mountains, elev. 2000 feet (n. 1544 and 1544 ?). 
2. Polypodium Grammitidis (Br. Prodr. 147); fronde glaberrima lineari v. lineari-oblonga pro- 
funde decursivo-pinnatifida, pinnis linearibus integris lobato-dentatis v. rarius pinnatifidis, lobis interdum 
elongatis caudatisve, soris globosis oblongisve.— Z7. Antarct. p. 111; Fl. N. Zeal. ii. 41. Grammitis 
heterophylla, Lad. Fl. Nov. Holl. ii. p. 90. t. 239. Xiphopteris heterophylla, Spr. Syst. Veg. iv. 44. 
. (Gunn, ll, 1543.) 
Has. Abundant on subalpine rocks, forming matted patches.—(v. v.) 
Distris. New Zealand, Java. 
Roots fibrous. - Fronds an inch to a span long, tufted, linear-oblong, ovate or lanceolate, coriaceous, opague, 
scaly at the very base of the stipes, perfectly glabrous elsewhere, deeply pinnatifid. Pinnules somewhat distant, 
linear, blunt, decurrent, guite entire, or lobed, or subpinnatifid, often irregularly, with one or two lobes lengthened 
or running out into a tail. Sori round or oblong. Rachis and short stipes winged nearly to the base.—Dwarf 
states have small, linear, lobed fronds. 
Gen. XVIII. PHYMATODES, Presi. 
Sori in sp. Tasmanize uniseriales, plus minusve fossa frondis immersi, globosi v. oblongi, nudi. Pene 
furcatee, omnes anastomosantes, areolis subhexagonis; venulis paucis, areolis liberis.— Rhizoma repens, 
squamosum.  Frondes coriacee, simplices v. Pinnatifide. Stipes basi articulatus. 
A very abundant tropical genus of Ferns, generally growing on trunks of trees, distinguished by the naked 
(large) sori partly sunk in a pit of the frond, and the anastomosing veins. The fronds are coriaceous, simple or 
pinnatifid, perfectly glabrous, rising from a stout, creeping rhizome. (Name from pupa, a swelling ; in allusion to 
the thickened base of the articulated frond.) 
1. Phymatodes Billardieri (Presl, Pterid. 196); frondibus coriaceis glaberrimis integris piunati- 
fidisque, pinnis remotis approximatisve anguste linearibus v. late oblongis margine incrassatis, soris sub- 
saccatis solitariis, rhizomate glaucescente crasso subsguamoso.— 77. Antarct. i. 111; Fl. N. Zeal. ii. 42. 
Polypodium, Br. Prodr. 147. P. scandens, Lab. Fl. Nov. Holl. i. p. 91. t. 240 (non Forst.). (Gunn, 6.) 
Has. Abundant on rocks and trunks of trees.—(v. v.) 
Distris. Australia, New Zealand, Pacific Islands, Malay Islands. (Cultivated in England.) 
A very common and variable plant.—Rhizome stout, creeping, generally quite glaucous, partially scaly, some- 
times thickly covered with membranous pales. Fronds numerous, 3 inches to 1% foot long, coriaceous, perfectly 
smooth, shining, with a thickened margin; some entire, lanceolate, acute, others broader and pinnatifid; pinnules 
close or distant, narrow-linear or broadly oblong; margins thickened, blunt or acute. Sori numerous, large, glo- 
bose or oblong, partially sunk in the frond. Costa very stout and prominent. Stipes stout, scarcely winged above, 
obscurely jointed on to the rhizome. 
Gen. XIX. GRAMMITIS, Sw. 
Sori medio venule affixi, oblongi v. lineares, uniseriales (in sp. Tasmania), coste obliqui, nudi. Vene 
simplices v. furcatee, immerse, libere.—Rhizoma repens, squamosum, breve v. elongatum. Frondes cespi- 
Lose, coriaceg ; venis immersis, inconspicuis. 
Rhizome creeping, often short, scaly. Fronds densely crowded, 4 inch to a foot long, quite glabrous, rarely
