The purpose of the Mo'orea Biocode Project is to "create the first comprehensive inventory of all non-microbial life in a complex tropical ecosystem" (http://
mooreabiocode.org). The inventory will include molecular, morphological, and
ecological data, and serve as a valuable reference library for species identification
and further ecological and systematic studies. Studies of ferns and lycophytes
(i.e., "pteridophytes"), in particular, will benefit from this inventory because it
will enable rapid identification of gametophytes based on DNA sequences, thus
enabling detailed field studies of this ecologically important yet poorly known
life stage. Initial field work has focused on collecting and identifying sporophytes
based on morphology; DNA data and further collections of sporophytes and
gametophytes will be added as the project progresses.
Murdock and Smith (2003) compiled a list of 80 Mo'orean pteridophytes
based on previous literature reports (8 species) and examination of herbarium
specimens (72 species); further records were added by Ranker et al. (2005; 8
species), Nitta (2008; 3 species), and Rouhan et al. (2008; 1 species). However,
previous lists of Mo'orean pteridophytes lacked sufficient sampling of the tallest

peak on the island, Mt. Tohiea (1207 m). Additional field surveys were
conducted during September 12-13, 2006, September 6-27, 2008, and August
11-28, 2010 as part of the Mo'orea Biocode Project that included explorations of
Mt. Tohiea and yielded 32 new species records from this site; an additional 10
new species records were found on other parts of the island, bringing the total
number of Mo'orean pteridophytes to 132 species (including at least 122 native
species; the above species counts do not add up exactly due to taxonomic
changes]. Furthermore, examination of herbarium specimens at PAP revealed
many earlier collections made on Mt. Tohiea and Mt. Mou'aputa by J. Florence
and others which had not been included in the lists compiled by Murdock and
Smith (2003] or Ranker et al. (2005), and are listed here (26 species; including
several species listed on the PAP website [Florence et al., 2007] for which
specimens were unavailable at the time we visited the herbarium]. Collection
data, previously known distributions based on published records and
specimens available at UC, and taxonomic notes (when appropriate] are given
for each new record. Species identifications are based on morphology and may
be subject to revision as molecular data become available, especially for
uncertain taxa. Family treatment follows Smith et al. (2006], except for the
acceptance of Athyriaceae as distinct from Woodsiaceae. All data of specimens
collected as part of the Mo'orea Biocode Project, including images, are freely
available online at http://biocode.berkeley.edu.

AMERICAN FERN JOURNAL: VOLUME 101 NUMBER 1 (2011)
The sole Mo'orean collection of this species differs from Plesioneuron
tahitense Holttum, endemic to Tahiti, in lacking sporangial setae and the basal
pinna lobes only slightly, if at all, reduced. The only other Plesioneuron
occurring in the Society Islands (Tahiti, Mo'orea) is P. attenuatum (Brack.)
Holttum, also known from the Bismarck Archipelago and Samoa (Holttum,
1977). This differs by its larger fronds, broader and longer pinnae (to 25X4 cm;
to 8 X 2 cm in Nitta 281] with more oblique and falcate segments, basal
segments of at least the distalmost pinnae strongly reduced, persistent stipe
base scales, and relatively large, tan indusia.

Closely related Pneumatopteris glandulifera (Brack.) Holttum, known from
Rarotonga, Samoa, the Solomon Islands, and New Hebrides (Holttum, 1977),
may occasionally be confused with P. mesocarpa, but differs in absence of
indusia.
