摘要

图为Syzygiumtriflorum t.t.h hoang, Kim Thanh， S.Tagane和D.H.Cuong, sp. nov，产自越南昆朱朗自然保护区。该新种与近缘种Syzygiumskiophilum的不同之处是，其小枝呈4角，红灰色，叶长圆形，先端渐狭，次脉较少，26-30对，花序完全腋生，苞片披针形卵形，花无梗，倒锥状托杯（花蕾略呈梨形），雄蕊较多，18-28。在2024年7月的雨季观察到花朵和果实。本新种生长在以Dacrydiumelatum和Dacrycarpusimbricatus为主的阔叶和针叶混交林下。

Syzygiumtriflorum (Myrtaceae), a new species from Vietnam.

Syzygiumtriflorum T.T.Hoang, Kim Thanh, S.Tagane & D.H.Cuong, sp. nov., from Kon Chu Rang Nature Reserve, Vietnam, is described and illustrated. The new species is distinguished from related species, Syzygiumskiophilum, by its having 4-angled and reddish-grey twigs, oblong leaves with an attenuate apex, less secondary veins of 26-30 pairs, exclusively axillary inflorescences, lanceolate-ovate bracts, sessile flowers, obconical hypanthium (slightly pyriform in flower buds) and more stamens of 18-28. The flowers and fruits were observed in the rainy season, July 2024. This new species grows under a mixed broad-leaved and coniferous forest dominated by Dacrydiumelatum and Dacrycarpusimbricatus.
