late hairs, segments 2 to 3 mm long, 0.6 to 1 mm wide, ciliate
with clustered stellate hairs with four to six branches from
stouter stalk-cells, the laminar surface also bearing some similar
but solitary hairs; cells mostly isodiametric, small, walls thin
and undifferentiated; sori as wide as the segments, and, except
for the hairs, shorter than wide, involucre cleft to the immersed
broadly cuneate or rounded base, lips long-ciliate with branched
and stellate hairs, receptacle included, columnar.
Specimen: NEW ZEALAND, Kirk 261, 803, Ranft, Cunningham,
Petrie, Bell, Smith. STRAITS OF MAGELLAN, Safford 368, bears
no hairs on the lamina.
9. Subgenus APTEROPTERIS nomen novum
Lamina vera omnino carente, filamentis brevibus cellularum
axibus frondis ubique excurrentibus pilis stellatis dense obtectis
substituta, segmentis frondis deinde crasse filiformibus haud
applanatis.
A single species, related to Sphaerocionium as shown by the
stellate pubescence, endemic in New Zealand.
127. HYMENOPHYLLUM MALINGII (Hooker) Mettenius.
Hymenophyllum Malingii (Hooker) METTENIUS, Hymen. (1864) 423,
pl. 1, fig. 32 (non rite); GIESENHAGEN, Flora (1890) 448, pi. 4,
fig. 25.
Trichomanes Malingii HOOKER, Garden Ferns (1862) pl. 64.
Caudex long, slender, filiform; stipites scattered on the caudex rarely
more than an inch long, slender; fronds two to four inches long, oblonglanceolate, tri-quadripinnate, or rather perhaps pinnatifid, destitute of any
wing or foliaceous portion, consisting of rachis alone; the ultimate branches
are often forked, and in the fertile fronds almost all the branches are
soriferous at the apex, and the whole frond is clothed with a dense stellated
pubescence of a ferruginous colour on one side and a pale grey on the
other; involucres terminal, subhemispherical, of a thick and firm texture,
obscurely two-lipped, and with the lips lobed; column scarcely exerted,
thick, fleshy, fusiform.
Hab. Mr. Maling, it' appears, is the fortunate discoverer of this remarkable hymenophyllaceous Fern on the ranges of Golden Bar, Middle
Island, New Zealand, and Mr. Brunner, Surveyor General, Middle Island,
on the "mountain-range between Blind Bay and Massacre Bay" (possibly
the same locality).-HOOKER, loc. cit.
Mettenius, loc. cit., says "H. Malingii... bietet das einzige
Beispiel unter den Hymenophyllaceen und Farnen iiberhaupt,
wo alle und jede Spur einer blattartigen Ausbildung fehlt."
Giesenhagen recognized the presence of parenchyma cells, each
growing out into a "papilla." It is the multitude of these papillae, standing closely side by side, and completely sheathing
