PTERIDOPHYTA
AD1 ANTIACEAE
I,argc, ercct, leathery fern up to 2 m or more in
height with pinnate, leathery fronds and sori densely
covering the lower surface of the upper, fertile
pinnae. Common on coastal rocks and in coastal
marshes, recorded only near the coast. Indigenous,
pantropical in distribution. McMullin 43; Setchell

Adiantum philippense L.
[maidenhair fern]
Delicate terrestrial fern with shiny black to dark
brown stipes, pinnate fronds with a lamina 15-20 cm
long, and sori extending all along the outer margins
of the fertile lobes. Uncommon in shady places,
reported from 50 to 200 m elevation. Indigenous,
widely distributed in the Old World tropics.

Bolbitis palustris (Bracken.) Hennipman
Medium-sized terrestrial fern with a short, creeping
rhizome, dimorphic pinnate fronds, margins cut
about 113 of the way to the midrib into rounded
lobes, and sori covering the entire lower surface of
the pinnae of fertile fronds. Occasional to locally
common in shady forest, reported from 30 to 600 m
elevation. Indigenous, reported from Australia to
Rapa. Reinecke 5c; Whistler 3534, 3616, 9078,

Pityrogramma brackenridgei (Carruthers) Maxon
Small terrestrial fern with a short rhizome covered
with linear brown scales, fronds tufted, lamina
pinnatifid, and sori covering the silvery
undersurface of the lobes. Occasional in sunny
places such as roadcuts, reported from near sea level
to 1550 m elevation. Endemic. A Kew specimen
was determined by Tyron in 1965 as P, chrysophylla
(Sw.) Link; if this is to be followed, the Samoan
plant would be indigenous rather than endemic.
