Abstract

A molecular phylogenetic study was conducted to determine the position of the Philippine endemic Miliusa vidalii in the tribe Miliuseae of family Annonaceae utilizing the combined cpDNA sequence data (trnL-F-matK-ndhF-psbA-trnH-ycf1). Bayesian inference and Maximum parsimony analyses revealed a robustly supported monophyletic Miliusa clade (PP=1.00; BS=93%). Miliusa vidalii nested within clade D (PP=1.00; BS=85%) shares similar features by having terminal inflorescences and a notably long pedicel. M. vidalii is resolved as sister to M. lanceolata, which shares morphological features such as length of pedicels, number of secondary veins, shape of leaf apex, and apiculate monocarp. This present study revealed that M. vidalii possesses a conspicuous glandular structure in the inner petals, a feature that is common only to species found in clade A. Therefore, increased taxon sampling is necessary to construct a stronger phylogenetic relationship within the genus.

从叶绿体DNA和形态上推断杨柳科杨柳科杨柳属植物的系统发育位置

利用组合cpDNA序列数据(trnL-F-matK-ndhF-psbA-trnH-ycf1)，对菲律宾特有的Miliusa vidalii在番荔枝科Miliuseae族中的位置进行了分子系统发育研究。贝叶斯推断和最大简约分析显示了一个强有力支持的单系Miliusa分支(PP=1.00;b = 93%)。在D支系内嵌套的密家蝇(PP=1.00;BS=85%)具有相似的特征，花序顶生，花梗特别长。在花梗的长度、次生脉的数量、叶尖的形状和具细尖的单果皮等形态学特征上，两者具有相同的特征。本研究表明，米达利在花瓣内具有明显的腺状结构，这一特征仅在a支系中发现的物种中存在。因此，需要增加分类群的采样以构建更强的属内系统发育关系。

The PJSB is a CHED recognized journal under CHED CMO 50 series of 2017. It is also included in the Clavariate Analysis (formerly a subsidiary of Thomson Reuters) Master Journal List under Zoological Record, BIOSIS Previews and Biological Abstracts.The PJSB is the official publication of the Association of Systematic Biologists of the Philippines (SEC Registration: Association of Philippine Taxonomists, Inc.). The organization financially supports the journal and all its endeavors. The journal aims to build up quality information on animal, plant and microbial diversity in the Philippines. Articles dealing with original research or reviews in Zoological, Botanical or Microbial Systematics, Ecology and Conservation Biology are welcome. Authors are advised to consult a recent issue of PJSB for the current format and style. All manuscripts are reviewed by at least two qualified referees.
