Description:
Ridsdalea philippinensis (Rubiaceae), a new species from the karst forest in El Nido (Palawan, Philippines), is described and illustrated. It is unique among Malesian Ridsdalea species in having a corolla tube that is
distinctly inflated at the apex, a character state also displayed by R. sootepensis and R. thailandica from Laos and
Thailand. Amongst others, R. philippinensis, however, differs from both of these species in having smaller flowers
and anthers that do not emerge from the corolla tube. An updated key for Philippine Ridsdalea is also presented.
