26. PETALOPHYLLUM, Gottsche. 
Fronds simple or 2 -fid, rooting below from the midrib, lamellate above. 
Inflorescence dioecious. Fruit from the back of tbe midrib. Involucre con- 
fluent with the perianth, quadrate, campannlate; mouth broad, open, undu- 
late, toothed. Calyptra large, globose, as long as the perianth or shorter. 
Capsule large, globose, on a slender fruitstalk, bursting irregularly ; elaters 
filiform, with 2 or 3 spiral, fibres ; spores large, reticulate. Antheridia dorsal 
at the forks, crowded, globose. 
A small British and Australian genus. 
1. P. Preissii, Gottsche ; — FI. N. Z. ii. 164. Frond ^ in. long, ob- 
ovate or cuneate; ventral surface rugulose, striate; dorsal with radiating 
lamellae, which are connate, forming little pockets at the costa. — Syn.Hep.472. 
Northern Island: Hawke’s Bay, on clay soil, Colenso. (S.W. Australia.) 
27. ZOOPSIS, Hook. f. and Tayl. 
Frond very slender, tufted, creeping, rigid, silvery-green, almost capillary, 
sparingly branched, of large tumid hexagonal cells ; midrib stout ; margins 
waved. Fruit lateral. Involucre of a few lanceolate scales. Perianth large, 
pedicelled, obovate-oblong, deeply laciniate. 
A very curious little plant, which I discovered in Lord Auckland’s group, and has since 
been found in Tasmania and New Zealand. 
1. Z. argentea, HooJc.f. and Tayl. FI. N. Z. ii. 164. Fronds 3 — §■ in. 
long, in. broad, of two lateral and one antero-posterior series of cells sur- 
rounding a central cord of filiform cells ; each of the marginal cells stands 
out like the tooth of a saw, and is terminated by an incurved bristle, which is 
not represented in the figure in FI. Antarct. The fruit is immature. — Syn.

tree-ferns, and amongst mosses, J. D. E. 
28. PODQMITRITJM, Mitten. 
Fronds erect from a creeping rhizome, stalked, oblong, with a stout 
midrib, membranous, entire. Inflorescence dioecious. Involucre from the 
base of the frond on the ventral surface, shortly pedicelled, with a few 
scales at the base. Perianth tubular, much longer than the involucre. Ca- 
lyptra included, bearing a few barren pistils, subcampanulate ; mouth lacerate. 
Capsule on a long fruitstalk, ovoid, 4-valved ; elaters filiform. Antheridia 
crowded on short pedicelled spikes. 
The only species known ; it is almost impossible to distinguish its barren fronds from those 
of the British Steetzia Lyallii and Syrnphyogyna subsimplex , Mitten.
