    A conservation genetic study of Rafflesia speciosa (Rafflesiaceae): patterns of genetic diversity and differentiation within and between islands (2018)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (2212-1676) vol.63 (2018) p.93
    Details
    Publication Date: 2018-07-13
    Description: Rafflesia speciosa is a threatened endo-holoparasitic species. It has several populations in the Central Panay Mountain Range (CPMR) of Panay island and a single population on Negros Island. Because R. speciosa is the only Philippine species of the genus that is not endemic to an individual island, it is a suitable species for improving our understanding of the factors underlying the high island endemism of Philippine Rafflesia. For this purpose and to inform the conservation management of R. speciosa, patterns of genetic diversity and differentiation were studied using 15 microsatellite loci and samples from nine populations. None of these populations shows evidence of inbreeding and R. speciosa has similar levels of heterozygosity as generally observed in outcrossing or perennial plant species. The results of AMOVA and Bayesian cluster analyses indicate that the Negros population is genetically differentiated from the CPMR populations. In addition, it has lower genetic diversity than similar-sized R. speciosa populations. These findings suggest that sea straits potentially provide significant reproductive barriers to Rafflesia species, and are perhaps responsible for their high island endemism. The general lack of genetic differentiation among the CPMR populations as suggested by the AMOVA, PCoA, and STRUCTURE results indicates recent gene flow among them and this finding improves our understanding of the geographical scale and context at which gene flow between Rafflesia populations occurs. Conservation efforts should be targeted towards avoiding further habitat degradation in the Negros population. We also recommend protective status for the entire CPMR and reforestation efforts to mitigate the severe habitat fragmentation, destruction, and degradation in this area.

    Taxonomy, ecology, and conservation status of Philippine Rafflesia (Rafflesiaceae) (2009)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (0006-5196) vol.54 (2009) nr.1/3 p.77
    Details
    Publication Date: 2015-03-06
    Description: The number of Rafflesia species (Rafflesiaceae) reported for the Philippines has grown explosively from two before 2002 to ten or eleven presently. We present an overview of the current knowledge of Philippine Rafflesia by providing a comprehensive account of all the recognized species with their taxonomy, distribution and ecology, plus a key and photographs to aid in identification. Their conservation status and that of the rain forest habitats they require is discussed.

    Another New Species of Rafflesia (Rafflesiaceae) from Luzon, Philippines: R. Leonardi (2008)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (0006-5196) vol.53 (2008) nr.1 p.223
    Details
    Publication Date: 2015-03-06
    Description: A new species of Philippine Rafflesia is described. Rafflesia leonardi is the eighth species of Rafflesia described from the Philippines and the fourth species from Luzon Island. It most closely resembles R. lobata and R. manillana in perigone colour and wart ornamentations and in the wide aperture relative to diaphragm diameter. It is, however, different from both of these and other Philippine Rafflesia species in its flower size and disk that lacks or has rudimentary processes.

    Revision of Coelogyne section Fuliginosae (Orchidaceae) (2000)

    Details
    Publication Date: 2015-03-06
    Description: Section Fuliginosae Pfitzer & Kraenzl. of the genus Coelogyne Lindl. is revised. With the help of a pollen study, principal component and cluster analyses with morphological characters and a survey of some additional data, two species are recognized (C. fimbriata and C. triplicatula), including one dubious variety (C. fimbriata var. acuminata). Eleven names are reduced to synonymy. Three species formerly included in sect. Fuliginosae by several authors are excluded ( (C. micrantha, C. treutleri and C. schilleriana).

    Rafflesia banahaw (Rafflesiaceae), a new species from Luzon, Philippines (2007)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (0006-5196) vol.52 (2007) nr.2 p.345
    Details
    Publication Date: 2015-03-06
    Description: A new small-flowered species of Philippine Rafflesia from Mt Banahaw in Luzon is described. Rafflesia banahaw is the seventh endemic species of Rafflesia found in the Philippines. It resembles R. baletei, but is different in, amongst other characters, having more confluent wart ornamentations, more numerous and densely packed processes on the disk, and more numerous, slightly immersed anthers. In addition, R. banahaw has glabrous ramenta which are grouped in dense clusters on the inside of the diaphragm and are more or less solitary on the inside of the perigone tube, whereas the ramenta of R. baletei are pubescent and distributed more uniformly.
