<b>Table S1</b> Dataset containing information on 2160 species of Leguminosae, with detailed descriptions of the presence and type of sculpturings and pockets on the wing petals of Papilionoideae, as well as other floral characteristics. <b>Non-papilionate</b> for flowers that do not have a corolla with a variable number, are absent, or undifferentiated; <b>Nearly-papilionate</b> for flowers with 5 free petals and mainly without differentiation (<i>sensu</i> Cardoso et al., 2013b); <b>Papilionate</b> for flowers with five petals differentiated into a dorsal standard (or vexillum), two lateral wings, and a pair of ventral keel petals (<i>sensu</i> Westerkamp, 1997).<b>附表S1</b> 本数据集收录2160种豆科（Leguminosae）植物的相关信息，详细记载了蝶形花亚科（Papilionoideae）翼瓣表面雕纹与凹陷的有无及类型，同时涵盖其他花部特征。<b>非蝶形花冠类群</b>指其花冠数目不定、缺失或未分化的类群；<b>近蝶形花冠类群</b>指具5枚分离花瓣且基本无分化的类群（依据Cardoso等，2013b的定义）；<b>蝶形花冠类群</b>指5枚花瓣分化为背部旗瓣（vexillum）、两枚侧生翼瓣及一对腹生龙骨瓣的类群（依据Westerkamp，1997的定义）
