Rafflesia banahaw (Rafflesiaceae), a new species from Luzon, Philippines
Provedor de dados: 16
Autores: Barcelona, J.F.; Pelser, P.B.; Cajano, M.O.
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.

A conservation genetic study of Rafflesia speciosa (Rafflesiaceae): patterns of genetic diversity and differentiation within and between islands
Provedor de dados: 16
Autores: Pelser, P.B.; Nickrent, D.L.; Barcelona, J.F.
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...

Taxonomy, ecology, and conservation status of Philippine Rafflesia (Rafflesiaceae)
Provedor de dados: 16
Autores: Barcelona, J.F.; Pelser, P.B.; Balete, D.S.; Co, L.L.
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.

Revision of Coelogyne section Fuliginosae (Orchidaceae)
Provedor de dados: 16
Autores: Pelser, P.B.; Gravendeel, B.; Vogel, E.F. de.
Section Fuliginosae Pfitzer &amp; 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).

Another New Species of Rafflesia (Rafflesiaceae) from Luzon, Philippines: R. Leonardi
Provedor de dados: 16
Autores: Barcelona, J.F.; Pelser, P.B.; Cabutaje, E.M.; Bartolome, N.A.
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.
