本文描述了产于菲律宾的越橘属两个新种,并从历史标本馆中收集了插图。产自菲律宾北方吕宋岛的Vaccinium burburan在形态上与V. tenuipes相似,但区别在于具有较短的叶柄、花梗和花冠,正面具短柔毛的叶片,基部心形,顶部具短柔毛的花冠,以及整个的短柔毛花丝。它是唯一的两个物种的越桔在菲律宾已知有一个心形的叶片基地。乌饭树被认为是极度濒危。来自菲律宾南部棉兰老岛的Vaccinium jubatum在形态上类似于V. sylvaticum,但区别在于具有具牙齿的叶片边缘,较短的花序和花梗,无毛的花萼和较短的花丝。V.jubatum的齿状叶片边缘独特地将其与其他菲律宾越橘属物种区分开来。目前关于乌藨子的保护状况的研究资料不足。这些发现进一步增加了菲律宾目前已知的越桔物种数量至40种。
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.
