Volume 47 of the Flora of Pan-Himalaya covers five families (Aquifoliaceae, Helwingiaceae, Campanulaceae, Lobeliaceae, and Menyanthaceae), 18 genera, and 192 species, among which one genus (Himalacodon) and 80 species are endemic to the Pan-Himalaya. The nomenclatural novelties in the volume are four new species, one new subspecies, three new combinations, one new status, and 10 new synonyms. 48 lectotypes are newly designated. Eight expeditions were made to the Pan-Himalaya for field observations and collection of materials. The author and his team determined three new genera, Pseudocodon, Himalacodon and Pankycodon, and merged two genera, Campanumoea and Leptocodon, into Codonopsis. In addition to the five new taxa published in this volume, eight other new species (one in Ilex, seven in Codonopsis) are described.
De-Yuan Hong is a professor at the Institute of Botany, Chinese Academy of Science.
