Bartonia verna (Michaux) Rafinesque ex Barton. Phen: (Nov-) Jan-Apr (-Jun); Apr-Jun. Hab: Wet pine savannas, shores of Coastal Plain depression ponds, interdune swales, other moist sands. Dist: VA (one site known from City of Virginia Beach) (Belden et al. 2004) and se. NC (Carteret County) south to s. FL, west to se. TX.
Origin/Endemic status: Endemic
Taxonomy Comments: Wood & Weaver’s (1982) speculation that B. verna is an outlier relative to the other species appears not to be true, with the deeper division being between B. verna / virginica on the one hand and the B. paniculata subspecies on the other (Mathews et al. 2009).
