Istanps: From Mangonui and Kaitaia southwards, not uncommon in forests. Sea- 
level to 3000 ft. 
Taken in a broad sense, this is a widely distributed plant, found in Australia and 
Tasmania, Polynesia, Japan, South Africa and Mauritius, and extratropical South 
America. It is easily recognized by the extremely slender capillary stipes, pendulous 
pale glaucous-green fronds, broad flat entire segments, and large orbicular sori. When 
growing in exposed places it is often much dwarfed, with closely imbricating pinnae, 
constituting Colenso’s H. imbricatum. _ |

2. H. sanguinolentum, Swartz Syn. Fil. (1806) 149.—Forming matted 
patches on the trunks or branches of trees or on rotten logs. Rhizome 
rather stout, creeping, much branched, usually bristly with reddish- 
brown hairs. Hronds erect or decurved, somewhat opaque, dull olive- 
green, reddish-brown when dry, 2-9in. high, broadly ovate or oblong, 
3-pinnatifid, glabrous or the stipes and rhachis with scattered red-brown 
hairs when young. Stipes rather stout, narrowly winged above; rhachis 
broadly winged throughout, stout, flexuose. Primary pinnae close or 
rather distant, spreading, rarely decurved; secondary short, deeply 
pinnatifid. Segments narrow-linear, obtuse, flat or the margins undulate. 
Sori mainly in the upper part of the frond, usually terminating short 
somewhat contracted lateral segments, quite free or very slightly sunk 
at the base. Indusium broader than the segment, broadly ovate or 
suborbicular, 2-valved to the base; valves obtuse, entire or slightly 
sinuate, often crested on the back.—H. polyanthos Swartz Syn. Fil. (1806)

NortH AND SourH Isnanps, Stewart Istanp, AUCKLAND IsLANDS: Abundant 
in forests throughout. Sea-level to 3000 ft. 
One of the most abundant species of the genus in New Zealand. It stains paper 
brown when drying, and gives off a peculiar odour, which it often retains for years. 
The species, or allied forms, are found in almost all tropical countries, but apparently 
nota Australia. 
3. H. villosum Col. in Tasm. Journ. Nat. Sci. ii (1844) 185.—Forming 
dense matted patches on the trunks of trees or amongst moss. Rhizome 
much branched, wiry, creeping. Fronds erect or decurved, opaque, dull 
brownish-green, 2-6 in. long, 1-2} in. broad, broadly ovate to ovate-lanceo- 
late, acuminate, 3-4-pinnatifid. Stipes 1-3in. ‘ong, usually narrowly winged 
above, villous with scattered spreading hairs; rhachis narrowly winged 
throughout, rather slender, flexuous, more or less villous, as are the partial! 
rhachides and costae. Primary pinnae closely placed, often overlapping, 
lanceolate-deltoid ; secondary rhombic-ovate, again once or twice pinna- 
tifid. Ultimate segments crowded, very narrow, linear, obtuse, flat. Sori 
numerous, terminating the segments, free. Indusium broadly ovate, obtuse 
or subacute, broader than the segments, 2-valved to the base; valves
