Filices. | FLORA OF TASMANIA. 145 
$ a. Fronds simply pinnate; pinne toothed, scarcely lobed. Involucre with one free margin. 
l. Asplenium flabellifolium (Cav. Prel. 1801. p. 258); parvulum, flaccidum, frondibus decum- 
bentibus, lineari-elongatis pinnatis, pinnis rhombeis breviter stipitatis antice crenato-dentatis, rachi levi 
filiformi apice elongato radicante.—Sw. Fil. p. 81. t. 31. f. 2; Br. Prodr. 150; Fl. N. Zeal. ii. 33. 
(Gunn, 22.) 
Has. Abundant in most parts of the Island, especially in rocky or stony soil.—(v. v.) 
Disreıs. South-eastern and Western Australia, New Zealand. (Cultivated in England.) 
Fronds tufted, straggling, prostrate or pendulous, slender, weak, flaccid, 3-8 inches long, pinnate, quite gla- 
brous. Pinne very variable in size and shape, 4-2 inch long, shortly stipitate, rhomboid or orbicular, broadly 
cuneate or rarely reniform at the base; outer margin coarsely crenate or lobed. Sori radiating from the base of the 
pinna. Rachis filiform, elongated, its apex without pinnz, often rooting.— This is a very distinct species from any 
of the following. 
2. Asplenium Trichomanes (Linn. Sp. Pl. 1540); frondibus parvulis pinnatis subcoriaceis ceespi- 
tosis erecto-patentibus lineari-elongatis, pinnis rotundatis oblongisve obtusis crenatis basi cuneato-truncatis, 
rachi stipitegue nigris.— Eng. Bot. t. 576. (Gunn, 37, 1592.) 
Has. Clefts of rocks by the Acheron and Franklin Rivers, Gunn.—(v. v.) 
Disrgis. New South Wales, Victoria, South Africa, Pacific Islands, South America, and throughout 
the temperate regions of the northern hemisphere. (Common in Britain.) 
A less straggling plant than 4. flabellifolium, readily distinguished by its black stipes and rachis, and more 
coriaceous fronds that do not root at the apex. 
3. Asplenium obtusatum (Forst. Prodr. n. 430); frondibus coriaceis ceespitosis erectis v. pendulis 
pinnatis, pinnis breviter stipitatis oblongis oblongo-lanceolatisve obtusis acutis acuminatisve serratis crena- 
tisve basi obligue cuneatis rotundatis truncatisve, rachi crassa marginata glaberrima v. sparse subsguamoso- 
pilosa, stipite basi sguamato, sguamis nitidis. 
Var. a; fronde erecta, pinnis valde coriaceis obtusis acuminatisve, venis ut plurimum simplicibus.— 
A. obtusatum, Forst. Prodr.; Lab. Fl. Nov. Holl. ii. p. 93. t. 249. f.2; Br. Prodr. 150; Schkuhr, Fil. 
i. p. 6.1. 68; Fl. Antarct. p. 108 ; Fl. N. Zeal. ìi. 33; Hook. Fil. Exot. t. 46. (Gunn, 1527.) 
Var. 8. obliquum; pinnis coriaceis elongatis lanceolatis acuminatis, soris linearibus, venis subremotis 
simplicibus furcatisve.—47. Antarct. p. 108; Fl. N. Zeal. ii. 33. A. obliquum, Forst. Prodr. n. 429; 
Schkuhr, Fil. t. 115 Lab. l.c. t. 249. f. 1. A. oblongifolium, Col. in Tasm. Phil. Journ. 
Has. Very abundant, especially on maritime rocks.—(v. v.) 
Disrris. South-eastern Australia, New Zealand, Lord Auckland’s and Campbell’s Islands, South 
Africa. (Cultivated in England.) 
The form I have called var. a is an extremely abundant Fern in the southern hemisphere, especially on mari- 
time rocks, and represents in these regions its very near ally, the common 4. marinum of England, from which it 
differs chiefly in the upper pinnze being confluent into a broader terminal pinna, and in the generally simple veins, 
characters which I fear may prove inconstant.— ronds very thick and leathery, tufted, 3 inches to 3 feet long, erect 
or pendulous, pinnate; pinne 1-4 inches long, stalked, linear- or oblong-lanceolate or oblong, blunt or sharp; dase 
truncate, cuneate, or rounded ; margin coarsely crenate or serrate. Veins often quite simple. Rachis very stout, 
compressed, margined, glabrous or with a few scattered soft hairs. Stipes covered at the base with long, broad; 
erect, shining, subulate scales.—Small plants have only one or two pairs of pinne, which are often short and blunt. 
Sometimes the lower pinne are lobed or pinnate at the base.
