泛热带姜科是姜目中最大的科，有 53 属、1200 多种。该科的分类于 1889 年首次提出，此后经过其他人的改进，根据形态特征（例如子房中的子房数和胎盘数量、雄蕊的发育、可育花药的修饰以及根茎-芽-叶方向）识别出四个族（Globbeae、Hedychieae、Alpinieae 和 Zingibereae）。基于核内转录间隔区（ITS）和质体 matK 区域 DNA 序列的新系统发育分析表明，至少其中一些形态特征是同源的，其中三个部落是并系群，非洲管唇属和婆罗洲属 Tamijia 是基础进化枝。前者的 Alpinieae 和 Hedychieae 大部分是单系类群，后者包括 Globbeae 和 Zingibereae。这些系统发育研究的结果用于提出姜科的新分类，该分类识别四个亚科和四个族： Siphonochiloideae (Siphonochileae)、Tamijiioideae (Tamijieae)、Alpinioideae (Alpinieae、Riedelieae) 和 Zingiberoideae (Zingibereae、Globbeae)。讨论了与该分类一致的形态特征以及各种单型属的分类地位。
The pantropical Zingiberaceae is the largest family in the order Zingiberales with 53 genera and over 1200 species. Classifications of the family first proposed in 1889 and refined by others since that time recognize four tribes (Globbeae, Hedychieae, Alpinieae, and Zingibereae) based on morphological features, such as number of locules and placentation in the ovary, development of staminodia, modifications of the fertile anther, and rhizome-shoot-leaf orientation. New phylogenetic analyses based on DNA sequences of the nuclear internal transcribed spacer (ITS) and plastid matK regions suggest that at least some of these morphological traits are homoplasious and three of the tribes are paraphyletic, The African genus Siphonochilus and Bornean genus Tamijia are basal clades. The former Alpinieae and Hedychieae for the most part are monophyletic taxa with the Globbeae and Zingibereae included within the latter, The results of these phylogenetic investigations are used to propose a new classification of the Zingiberaceae that recognizes four subfamilies and four tribes: Siphonochiloideae (Siphonochileae), Tamijioideae (Tamijieae), Alpinioideae (Alpinieae, Riedelieae), and Zingiberoideae (Zingibereae, Globbeae). Morphological features congruent with this classification and the taxonomic status of various monotypic genera are discussed.
