本文描述了产于菲律宾布卡斯岛和迪纳加特岛的桑寄生科植物Cyne一新种，命名为Cyne。巴塞隆纳在菲律宾植物学家朱莉F的荣誉。巴塞罗那利用完整的核核糖体DNA顺反子进行系统发育分析，证实它是C. banahaensis是该属6个种中唯一具有完整花部形态描述的种。该种与罕见的C.产于巴布亚新几内亚的一种穿叶植物，上部叶为合生穿叶，但与其它属植物的不同之处在于具有掌状叶脉，花序无盖，浅绿色花冠，雄蕊有花丝。没有Cyne quadriangula的模式标本存在，因此这个分类群只从原始的原生植物中被知道。它在布卡斯格兰德岛被重新发现，并被描述为该物种的新模式标本。修订了该属的描述和7个种的检索表。
A new species of Cyne (Loranthaceae) from Bucas Grande and Dinagat Islands, Philippines is described and named C. barcelonae in honor of the Filipina botanist Julie F. Barcelona. Phylogenetic analysis using the complete nuclear ribosomal DNA cistron confirms it is sister to C. banahaensis, the only species among the six in the genus with complete descriptions of floral morphology. The species is similar to the rare C. perfoliata of Papua New Guinea by having connate-perfoliate upper leaves but differs from others in the genus by possessing palmate leaf venation, inflorescences lacking an operculum, light green corollas, and stamens with filaments. No type material for Cyne quadriangula exists, thus this taxon is only known from the original protologue. It was rediscovered on Bucas Grande Island and that collection was described and used as the neotype for the species. A revised description of the genus and key to the seven species is provided.
