Taxonomic Comments
This record represents the narrow concept of Orbexilum pedunculatum not including O. psoralioides, following FNA (vol. 11, 2023). In contrast, Kartesz (1994, 1999) treated O. pedunculatum in a broad sense with two varieties distinguished: O. pedunculatum var. pedunculatum and O. pedunculatum var. psoralioides.
