Oxalis sect. Palmatifoliae (Oxalidaceae): Pollen grains morphology and orbicules diversity

Pollen morphology and orbicules characteristics were studied by means of transmitted light microscopy (LM) and scanning electron microscopy (SEM) within five species of Oxalis section Palmatifoliae endemic from southern South America. Oxalis pollen grain is generally 3-colpate and the shape is prola...
