Nepenthes Gracillima - Natural Hybrids

Natural Hybrids

In Nepenthes of Sumatra and Peninsular Malaysia, Charles Clarke lists the natural hybrid N. gracillima × N. macfarlanei. At the time of the book's publication, N. alba was considered a heterotypic synonym of N. gracillima. Since then, however, N. alba has been elevated to a species. As both N. alba and N. gracillima occur on Mount Tahan, from which Clarke recorded the hybrid, it is unknown which taxon was involved in the cross.
