Abstract- The sister group of the monophyletic tribe Argostemmateae, including Argostemma and Neurocalyx, is not the tribe Hedyotideae, or a part of it, as earlier assumed, but the monophyletic tribe Hamelieae, here redefined. It comprises the genera Hamelia, Hoffmannia (here including Xerococcus), Deppea (here including Schenckia), Pinarophyllon, and Omiltemia. The two tribes Argostemmateae and Hamelieae are a monophyletic group characterized by seven synapomorphies. A cladogram is presented showing the relationships of the seven genera based on 31 characters. One group of characters, the aestivation of the corolla, is shown to be much more complicated than hitherto assumed. In the Hamelieae the aestivation can be imbricate (to the right or to the left and quincuncial or not), contorted (to the right), alternative, or even valvate. The Argostemmateae occur in the Old World Tropics, and their distribution supports the hypothesis that at least parts of southeast Asia are a part of Gondwanaland. The vicariant pattern within the Argostemmateae indicates that the large area from west Africa through northern India to southeast Asia is vicariant to Ceylon and southern India. The distribution of the Old World tribe Argostemmateae is vicariant to the essentially Central American tribe Hamelieae.
摘要——单系类群银柴族(包括银柴属和尖帽草属)的姐妹群并非如之前所认为的那样是耳草族或其一部分,而是重新定义的单系类群长隔木族。它包括长隔木属、霍夫曼木属(此处包括旱球属)、德佩木属(此处包括申氏木属)、针叶木属和奥米木属。银柴族和长隔木族这两个族构成一个具有七个共衍征的单系类群。给出了一个分支图,展示了基于31个性状的七个属之间的关系。其中一组性状,即花冠的花被卷叠式,比迄今所认为的要复杂得多。在长隔木族中,花被卷叠式可以是覆瓦状(向右或向左且是否为交互对生)、旋转状(向右)、互生,甚至是镊合状。银柴族分布于旧世界热带地区,其分布支持了东南亚至少部分地区是冈瓦纳大陆一部分的假说。银柴族内部的替代分布模式表明,从西非经印度北部到东南亚的大片区域与锡兰和印度南部是替代分布。旧世界族银柴族的分布与基本上分布于中美洲的族长隔木族是替代分布。
