This species has been difficult for me to learn to tell apart from the Asiatic dayflower (Commelina communis). Eventually I learned that there were two features which help to tell the two apart. First, the spathe of the Asiatic dayflower is open along the top while the spathe of the erect dayflower is to some extent closed. Second, the nodes along the stems are different between the two species. The sheath of the Asiatic dayflower clings tightly to the stem while that of the erect dayflower actually bends back. See the images both for this species and for the Asiatic dayflower to see the differences between the top of the spathe and the sheath of the node.
