Abstract

Gaultheria rostrata, a new species of wintergreen endemic to Mindanao Island, Philippines, is here described and illustrated. It resembles Gaultheria bartolomei, endemic to Luzon Island, but differs by having a terrestrial habit, shorter petioles, longer pedicels, white or pale-pink corollas, coiled corolla lobes, longer anther tubules, and a longer style. The flowers of Gaultheria rostrata are unique among Asian species of Gaultheria on account of their coiled corolla lobes exposing the anthers and style at anthesis. This discovery raises the number of Gaultheria species in the Philippines to 16.
