图2 鼠尾草属杠杆状雄蕊的结构多样性(Cla?en-Bockhoff et al., 2004a)。A, 双药室杠杆状雄蕊。B, 杠杆臂弯曲的单药室雄蕊。C, 杠杆臂直伸的单药室雄蕊。D, 杠杆下臂退化的雄蕊。E, 具有三维下臂结构的雄蕊。图中阴影区为杠杆臂或增长的药隔, 深色区域为花粉囊或药室, 空白区为花丝。

Fig. 2 Morphologic diversity of lever-like stamens in Salvia (Cla?en-Bockhoff et al., 2004a). A, Bithecate lever-like stamen. B, Monothecate stamen of curved connective arms. C, Monothecate stamen of straight connective arms. D, Stamen of reduced lower connective arm. E, Stamen of three-dimensional lower connective arm. Shaded area represents elongated connective arms, black area for thecae, clear area for filament.
