Pulping properties and fibre characteristics of wood from eight-year-old ramets of 6 diploid and 5 tetraploid clones of Acacia mangium grown in Vietnam are reported. Individual clones were represented by two or three ramets. While kraft pulp yield at kappa 20 was very similar for diploid and tetraploids clones, tetraploid clones produced pulp with significantly longer (883 urn) and wider (20.0 μrn) fibres, compared to the diploid clones (683 urn and 15.6 μrn). The tetraploid cell wall thickness was greater, resulting in a coarser pulp. Pulmac fibre strengths of the tetraploid were greater than those of the diploid, although their fibre bonding area was lower. The kraft pulp of the best of the tetraploid clones had higher bulk, porosity and tear strength at constant tensile than pulp from a mix of diploid clones and was similar in these traits to softwood pulp.

Annamocalamus H. N. Nguyen, N.-H. Xia & V. T. Tran (Poaceae- Bambusoideae), a new genus from Vietnam, is described and illustrated. It is based on the species Annamocalamus kontumensis H. N. Nguyen, N.-H. Xia & V. T. Tran. The new genus shares some morphological characters with Melocanna Trin. and Stapletonia Dash & al. but can be recognized by its shorter rhizome and the occurrence of pseudospikelets. © CONSERVATOIRE ET JARDIN BOTANIQUES DE GENÈVE 2013.

Maclurochloa K. M. Wong (Gramineae: Bambusoideae) is a genus of clambering bamboos with dry caryopses. It was thought to be monotypic in Peninsular Malaysia, but here we report one more species from Vietnam which is new to science: Maclurochloa tonkinensis H. N. Nguyen et V. T. Tran sp. nov. Maclurochloa tonkinensis is most similar to M. montana (Ridl.) K. M. Wong from which differs mainly by having internodes 50-58 × 3.0-3.5 cm and culm leaves with auriculate sheaths and erect blade. © 2013 The Authors.
