Abstract
A new micro-endemic species of Rhododendron is described and illustrated from botanical expeditions to the Victoria-Anepahan Mountain Range on the island of Palawan. It closely resembles Rhododendron wilkiei but differs in having leaves with laminae that are narrowly elliptic-oblanceolate, have adaxially indistinct venation, and are arranged in 4–8 active and mostly terminal pseudowhorls along the length of the stem; bracts without scales on the margin; yellow flowers with a red corolla tube interior that is densely hairy towards the base; and hairy anther filament bases. Morphological and geographical data place the species in Rhododendron sect. Schistanthe. The new species, together with a first record of Rhododendron vidalii on Palawan as part of this research, represent the tenth and eleventh members of this genus recorded from the island. A revised key to the Palawan species of Rhododendron is provided.
期刊介绍：
Edinburgh Journal of Botany is an international journal of plant systematics covering related aspects of biodiversity, conservation science and phytogeography for plants and fungi. The journal is a particularly valued forum for research on South East and South West Asian, Sino-Himalayan and Brazilian biodiversity. The journal also publishes important work on European, Central American and African biodiversity and encourages submissions from throughout the world. Commissioned book reviews are also included. All papers are peer reviewed and an international editorial board provides a body of expertise to reflect the wide range of work published and the geographical spread of the journal’s authors and readers. Published on behalf of the Royal Botanic Garden Edinburgh
