山茶族是山茶科植物中最大的成员，它包括一些重要的经济植物和广泛种植的植物，如饮料茶和一些木本观赏植物。利用5个基因组区域(叶绿体：ATPI-H、matK、psbA5‘R-ALS-11F、rbcL；核：叶)和代表该族5个属中的4个属的30个种(无精属、山茶属、多孢属和金针菌属)，对该族的系统发育进行了研究，并对该族的属进行了划分。结果表明，多孢子菌为单系种，茶亚科其他3个属的姊妹种为单系种，山茶属为单系种，金花茶属为多系种。一些茶亚科植物在核树和叶绿体树之间的系统发育位置不一致，这表明山茶属与金莲花属、多孢属和副肾属之间存在广泛的杂交。这些结果表明，杂交，而不是形态同源性，混淆了目前茶亚科的分类。此外，还讨论了拉普拉斯属的系统发育位置和可能的亲缘关系。
Tribe Theeae, which includes some economically important and widely grown plants, such as beverage tea and a number of woody ornamentals, is the largest member of the Theaceae family. Using five genomic regions (chloroplast: atpI-H, matK, psbA5'R-ALS-11F, rbcL; nuclear: LEAFY) and 30 species representing four of the five genera in this tribe (Apterosperma, Camellia, Polyspora, and Pyrenaria s.l.), we investigated the phylogeny of Theeae and assessed the delimitation of genera in the tribe. Our results showed that Polyspora was monophyletic and the sister of the three other genera of Theeae investigated, Camellia was paraphyletic and Pyrenaria was polyphyletic. The inconsistent phylogenetic placement of some species of Theeae between the nuclear and chloroplast trees suggested widespread hybridization between Camellia and Pyrenaria, Polyspora and Parapyrenaria. These results indicate that hybridization, rather than morphological homoplasy, has confused the current classification of Theeae. In addition, the phylogenetic placement and possible allies of Laplacea are also discussed.
