Begonia chingipengii from Gabaldon, Nueva Ecija, Luzon Island is described as a new species endemic to the Philippines. This is the latest addition to the newly delimited Begonia section Baryandra. It resembles Begonia trichochila but is distinguished by the variegated leaves with light green veins and midrib contrasting with the dark green adaxial surface and maroon abaxial surface, and its oblique leaf is elongated with an acuminate apex. The robust variegated leaves, large flowers and extensive inflorescence make it very attractive. © 2014 Magnolia Press. Source

Two new species of Ixora are described from the provinces of Palawan and Samar, Philippines: I. alejandroi and I. reynaldoi. The two new species are compared mostly with other species of the genus from the Philippines and neighbouring Asian countries. Ixora alejandroi is characterized by its elongated cyme with congested secondary axes, reddish-brown corolla, stigmatic lobes shortly cleft in the middle, round at tip; while I. reynaldoi is easily recognised by its pseudanthium-type, 9–15 flowered inflorescences, long bracteoles (3.5–8 mm long), and keeled, foliaceous calyx lobes (8–10 mm long). The conservation status of each species is proposed, using IUCN Criteria. © 2015 Magnolia Press. Source


The moss flora of Camiguin Island, based on a 2007 expedition conducted by the author, totaled 129 species in 66 genera and 29 families. This represents 17.36% of the 743 moss species and 26.83% of the 246 genera of mosses reported for the Philippines (Linis & Tan 2008). Of these, one taxon, Aerobryopsis cochlearifolia Dix., is reported for the first time in the archipelago. Floristically, Camiguin moss flora is identified more with Mindoro and Luzon within the Philippine archipelago. Likewise, the presence of moss taxa such as Glossadelphus hermaphroditus Fleisch, and Orthomnion javense (Fleisch.) T. Kop. highlights the role of Mindanao in enriching the moss flora of Camiguin Island. Finally, the importance of remaining forests on the island as a proposed protected area is discussed. © 2010 Royal Botanic Gardens and Domain Trust. Source

Aglaomorpha cornucopia (Copel.) M.C. Roos is an endemic and rare epiphytic fern from the Philippines. Ex situ germplasm storage and growth are important complementary tools for conserving this rare fern. This study was conducted to document the reproductive biology of this species. Mature sporophylls of A. cornucopia were collected in May, 2012 from Mt. Apo, the Philippines. Each sporangium bore 64 yellow, monolete spores. The average spore size was 49.3±3.7 μm. Fresh spores germinated 100% within one week of sowing (mean germination time (MGT) <1 week). Air-dried mature spores remained completely viable even after one year of storage at 3°C, although mean germination time was somewhat delayed (MGT=1.4 weeks). Spore germination was of the Vittaria-type, whereas gametophyte development was of the Drynaria-type. Adult gametophytes were cordiform-annual and gametangia were of the leptosporangiate type. Unicellular papillate hairs appeared on marginal, dorsal, and ventral surfaces of the gametophytes. Gametophytes first produced antheridia and archegonia after seven weeks of culture. Gametophytes began to sexually produce sporophytes after 13 weeks of culture. The rate of sporophyte production reached 64% after 26 weeks culture. Results of this study suggest that cold temperature spore storage and in vitro culture offer reliable techniques for conserving this rare fern. Source
