| The first putative hybrid tree species of the genus Bruguiera (Rhizophoraceae), B. × rhynchopetala, is reported from mangrove forests of China and Australia. It was described from China previously as a variety of B. sexangula. The hybrid is acknowledged as B. gymnorhiza × B. sexangula with parent species restricted to different parts of the Indo-West Pacific. The hybrid is recognised at north-eastern and south-eastern parts of the overlap area between parent distributions, but it appears absent in western parts. Further local assessments are needed across the range. Hybrid status is supported by: 1) intermediate and shared morphological characters; 2) distribution limited to areas of co-occurrence of B. gymnorhiza and B. sexangula; and 3) molecular... |

| A recent survey of mangroves in New Caledonia located 7 taxa of the genus Rhizophora – with 6 coexisting in one estuary. This is arguably the greatest concentration of co-occurring Rhizophora taxa anywhere. Two are well-known mangrove species of the Indo West Pacific, R. stylosa and R. apiculata, and another, R. samoensis resembles the widespread Atlantic East Pacific species, R. mangle. The other four are hybrid intermediates, R. × lamarckii (= R. stylosa × R. apiculata), R. × selala (= R. stylosa × R. samoensis), and two previously undescribed combinations, R. × tomlinsonii (R. apiculata × R. samoensis) and R. samoensis var. neocaledonica (= R. samoensis × R. × selala). The new entities are unknown elsewhere. While R. × tomlinsonii is considered endemic... |

| In Australia, New Guinea and the southwestern Pacific seven taxa are recognised in Sonneratia, of which three species are redescribed in view of their Indo-Malesian counterparts ( S. alba, S. caseolaris, S. ovata), one species is redescribed from its most likely Indo-Malesian equivalent (S. lanceolata, being distinct from S. caseolaris), one widespread hybrid is fully described (S. x gulngai being the putative synonym of S. alba x S. caseolaris), and two other hybrids (S. alba x S. gulngai, S. alba x S. lanceolata) of very limited occurrence are described as sub-units of their closest ‘parental’ forms. A key, descriptions and full synonymy are given as well as 2 distribution maps, 6 other figures and one table. |
