Journal ArticleRHODODENDRON ASTROPHORUM (ERICACEAE, RHODODENDRON SECT. SCHISTANTHE), A NEW MICRO-ENDEMIC SPECIES FROM CENTRAL PALAWAN, PHILIPPINESTamayo, Maverick; Marcos-Langbao, Abrila; Bustamante, Rene_Alfred Anton; Ang, Yu Pin; Schubert, Dale; Mustaqim, Wendy; Fritsch, Peter; Robinson, Alastair<p>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.</p>Edinburgh Journal of Botany2023-02-1610533618Edinburgh Journal of Botany801 to 140960-4286https://doi.org/10.24823/ejb.2023.19791754697; 1754667National Science Foundation
