鞘蕊属(学名:Coleus),或作鞘蕊花属,是一个一年生或多年生的草本或灌木植物的属。部分物种属于多肉植物,长有具肉质或块状的块茎或块根。 分布于旧世界(东半球)的热带与亚热带。 有关鞘蕊属、彩叶草属及马刺花属三者的关系很混乱:前两属的物种曾经被并归马刺花属,但结果使马刺花属在支序亲缘分析之下变成了马刺花亚族(Plectranthinae)的一个多系群。
现时最新的分类学处理重新建立鞘蕊属,212个物种分别来自马刺花属、密穗花属及排香草属;Equilabium在系统发育研究支持下从马刺花属独立出去成为一个属[2]。
鞘蕊属物种常被用作园艺植物而种植,当中尤以彩叶草最为常见。一方面,彩叶草的斑斓叶片使之成为一种受欢迎的园艺植物,而近年兴起的生酮饮食,亦因为彩叶草的根部丰富的营养素而使之大受欢迎。彩叶草喜光,但不适宜太阳直射,而是非直射的光线:因为直射的太阳光会破坏叶片上的色素,使叶片颜色变得单一;所以在户外时,彩叶草应完全遮光,只能照射日出时最柔和的日光[3]。
其他长有块根的鞘蕊属植物有被当作食粮而种植,计有Coleus esculentus、Coleus rotundifolius及Coleus maculosus subsp. edulis。
分类学
[编辑]鞘蕊属最早由若昂·德理路于1790年描述。以形态学特征为指导基础,将它由马刺花属(首先由夏尔·莱里捷在1788年描述)独立出来;其四条雄蕊融合在一起,而不是从基底起就已分开。1962年,约翰·肯尼斯·莫顿留意到雄蕊融合在一起的物种比过往所认知的其实更常见及广泛分布,所以把鞘蕊属物种合并进马刺花属,而彩叶草属(Solenostemon)及一些其他的属仍维持区隔。[4]大多数的来源都跟随莫顿进行鞘蕊属的合并;有些保持彩叶草属的独立,但其他则将它跟著鞘蕊属一起并入马刺花属。[2]
在2004年针对唇形科荆芥亚科罗勒族(Ocimeae)进行的初步研究表明,马刺花亚族(Plectranthinae)为单系群,有两个主要演化支:一个包含鞘蕊属的模式种,并包含彩叶草属;另一个包含马刺花属的模式种以及其他属,因此广义上马刺花属不是单系群。在2018年进行的更详细研究得出类似的结论,并建议应重新确认鞘蕊属(包含彩叶草属),对马刺花属进行更狭义的定义,并建立一个新的属Equilabium,主要来自热带非洲的前马刺花属物种演化支。2019年提供了实现此方法所需的许多新的双名组合。[2]
支序亲缘
[编辑]裴顿等人(2019)[2]基于其2018年的研究总结[5],出版了马刺花亚族(Plectranthinae)各属的支序亲缘图。下图中被裴顿等人接纳并构成广义的马刺花属的三个属以黄色底显示:
