Other species of Leontice like Leontice leontopetalum and its alkaloid petaline chloride has been tested on guinea pig isolated smooth muscle and heart.
In that case, outer staminodes may be differentiated as outer petaline structures, which confuses the limits between petals and staminodes as in Scytopetalaceae (Appel, 1996), or there is an outer receptacular corona without clear homology with staminodes (Passifloraceae: Bernhard, 1999a).
