Résumé :
|
A molecular technique (RAPD-PCR) is used to determine the relationship of an unknown Vaccinium from Vietnam to Vaccinia from throughout the south-east Pacific region. Based on the RAPD and morphological data, a new taxon, Vaccinium hiepii vander Kloet, sp. nov., is described. Cluster analyses (UPGMA, Neighbour-joining) clearly group V. hiepii with V. chunii, placing the new taxon within V. § Galeopetalum. Furthermore, Vaccinium § Bracteata sensu Sleumer (1941) is strongly supported by high bootstrap values within the dendrograms. Placement of V. petelotii within V. § Conchophyllum sensu Stevens (1969) is also possible.
