Última Pollen morphology of Philippine species of Phyllanthus (Phyllanthaceae, Euphorbiaceae s.l.) Naturalis Chen, Y.-J.; Chen, S.-H.; Huang, T.-C.; Wu, M.-J.. The pollen morphology of 21 Philippine Phyllanthus species belonging to five subgenera and eleven sections was studied using scanning electron microscopy. Eleven pollen types were recognized, of which seven were previously reported and four are newly described, i.e., the Phyllanthus erythrotrichus type, the P. glochidioides type, the P. securinegoides type and the Pilate type. The pollen morphology of the Philippine Phyllanthus species included in this study provides insight into the taxonomy as well as the phylogeny of these species.

Ano: 2009 URL: http://www.repository.naturalis.nl/record/524498 Phylogenetic biogeography of Euphrasia section Malesianae (Orobanchaceae) in Taiwan and Malesia Naturalis Wu, M.-J.; Huang, T.-C.; Huang, S.-F.. Species of Euphrasia are distributed in both hemispheres with a series of connecting localities on the mountain peaks of Taiwan and the Malesian region including Luzon, Borneo, Sulawesi, Seram and New Guinea. Two hypotheses are proposed to explain this distribution pattern. The Northern Hemisphere might have been the centre of origin or the Southern Hemisphere. This study aims to reconstruct the core phylogeny of Euphrasia in the connecting areas and tries to identify the migratory direction of Euphrasia in Taiwan and Malesia. The phylogeny of Euphrasia, including sections Euphrasia, Malesianae and Pauciflorae, is reconstructed with the chloroplast molecular markers rps2 gene, trnL intron and trnL-trnF intergenic spacer. The results suggest that the...
