An updated list of the species of Gaultheria (Ericaceae) from Myanmar is presented, with additions and corrections to a previously published list. Gaultheria natmataungensis, a new species from Natma Taung National Park, Chin State, Myanmar, is described and illustrated. It is the only species of Gaultheria endemic to the country. Additionally, G. griffithiana var. insignis is raised to the rank of species (G. insignis), and G. insignis and G. suborbicularis are newly recorded for Myanmar. Photographs of living plants of G. insignis are included, along with an updated description and illustration that incorporate new morphological data, including the first documentation of floral characters. Lectotypes are provided for G. fragrantissima, G. insignis, and G. nummularioides. A key to the species is provided. The number of Gaultheria species recorded from Myanmar is 24.

Two new species of Vaccinium from the Philippines are described and illustrated from historical herbarium collections. Vaccinium burburan from Luzon Island, Northern Philippines is morphologically similar to V. tenuipes, but is distinguished by having shorter petioles, pedicels and corolla, adaxially pubescent leaf blades with cordate base, apically pubescent corollas, and pubescent filaments throughout. It is only one of two species of Vaccinium in the Philippines known to have a cordate leaf blade base. Vaccinium burburan is considered critically endangered. Vaccinium jubatum from Mindanao Island, Southern Philippines, is morphologically similar to V. sylvaticum, but is distinguished by having a dentate leaf blade margin, shorter inflorescences and pedicels, a glabrous calyx, and shorter filaments. The dentate leaf blade margin of V. jubatum uniquely distinguishes it from other Philippine Vaccinium species. The conservation status of V. jubatum is considered data deficient. These discoveries further increase the current number of known Vaccinium species in the Philippines to 40.
