青藓科(Brachytheciaceae)隶属于藓类植物门(Bryophyta)、灰藓目(Hypnobryales).全世界青藓科植物有43 属，约560 种，是侧蒴藓类植物中种类较多的类群之一.而广义青藓属(Brachythecium)有160 种，是该科模式属，同时也是种类最多、分类学问题最多的属之一.2002 年，基于分子和形态学证据，俄罗斯学者Ignatov 和芬兰学者Huttunen 将
多倍化是植物物种形成最重要的方式之一，多倍化能提高物种或群体的生态适应性.乌头多倍体复合群(Aconitum carmichaelii Polyploid Complex)分布范围主要在我国的西南、华中和东北等地区，通常认为该复合群包含乌头(A.carmichaelii)、北乌头(A.kusnezoffii)和鸭绿乌头(A.jaluense)等种.
马蓝属(Strobilanthes Blume)隶属于爵床科芦莉花族(Acanthaceae,Ruellieae),主要分布于南亚和东南亚的热带地区,全世界约有450 种,我国约有120 种.马蓝属植物的主要特征为花丝联合成膜状,柱头开裂,后面的花瓣裂片缩短,两列毛分布在花瓣裂片内支撑花柱.本文以马蓝属为研究对象,在先前学者构建的国产马蓝属系统发育关系及分组的前提下,利用性状演化分析软件Mesqu
