Preliminary Catalogue of Vascular Plants in the Pan-Himalaya. 2019. XII, 371 p. gr8vo. Hardcover.- In English.

Generally speaking, the eastern Pan-Himalaya is much richer than the western Pan-Himalaya in species diversity. There are only 617 species of flowering plants recorded from the Wakha corridor in NE Afghanistan, with 103 species of the Asteraceae. 87 species of the Poaceae, 67 species of the Fabaceae, and only two species of the Orchidaceae (Podlech, 2012). On the other side, the eastern Pan-Himalaya is a biodiversity hotspot, with new species being continuously described even in recent years. For example, more than 50 new species of Saussurea DC. have been described from the eastern Pan-Himalaya within the last ten years

This catalogue includes 282 families, 2535 genera and 19. 462 species of vascular plants in Pan-Himalaya.
