Pteridophytes of Additional Mo'orea, New French Polynesia: Records Berkeley,Berkeley,California94720-24 Jean-Yves Meyer jarch,GovernmentofFrenchPolynesia Abstract. — The ferns and lycophytes of Mo'orea, French Polynesia were surveyed as part of t Mo'oreaBiocodeProjectdm-ingSeptember12-13,2006,September6-27,2008,andAugust11-2 2010,resultingincollectionof42speciesthathadnotbeenpreviouslyreportedtooccuronMo'on Specimencitations,previouslyknowndistributions,andtaxonomicnotes(whenappropriate)a given for each new record. New records include 16 species collected for the first time during t Mo'oreaBiocodeProject,and26speciescollectedpriortotheprojectbutnotincludedinpublishi oject.Ferns,Lycophytes,Pteridophytes 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 *Correspondingauthor'snewaddress:DepartmentofOrganismicandEvolutionaryBiology, Harvard University Herbaria, 22 Divinity Ave., Cambridge, MA 02138-2020, U.S.A.; email: jnitta@oeb.harvard.edu NITTA ET AL.: PTERIDOPHYTES OF MO 'ORE A 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. Athyriacae Deparia confluens (Kunze] M.

Endemic to Mo'orea pending further study. 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.
