Type.

Based on Eugenia densinevia Merr.

Notes.

Syzygium densinervium resembles S. fastigiatum (Blume) Merr. & L. M. Perry in having paniculate inflorescence, funnel-shaped hypanthium and persistent bracts and bracteoles. It differs by its rugulose hypanthial cup. I have examined an unidentified specimen, Henry 1998 at K [K 001003761] and found that it belongs to S. densinervium . I have also examined the isotype type of S. densinervium var. insulare from Taiwan and then placed it under S. densinervium . This species is distributed in the Philippines and Taiwan.

Specimens examined.

Taiwan, Botel Tobago, 7 Feb. 1980, Chang 14691 ( KYO); ibid., 6 Sept. 1980, Chang 14694 ( KYO).
