Ampelocissus asekii J. Wen, R. Kiapranis & M. Lovave, a new species of Vitaceae from Papua New Guinea

Abstract. A new species Ampelocissus asekii J.Wen, R.Kiapranis & M.Lovave of Vitaceae is described from Morobe Province of Papua New Guinea. It is a close relative of Ampelocissus muelleriana Planch., another endemic of New Guinea and differs from the latter by its densely woolly tomentose lower leaflet surface and much thicker leaflets. The new species is from the mid montane forests, whereas Ampelocissus muelleriana occurs in the lowland rain forests.
