Regularity: Regularly occurring
Global Range: Extreme southeastern Virginia to south-central Florida, west to southwestern Georgia and adjacent parts of the Florida panhandle (Cantino, 1982).
Physostegia leptophylla is distinguished from P. longisepala by calyx lobes rarely over 2.5 mm long, infrequently cuspidate; longest trichomes on raceme axis 0.1-0.13 mm long; lower stem leaves elliptical to lanceolate (rarely oblanceolate); leaves bluntly toothed, repand, or entire (rarely sharply serrate). P. leptophylla is distinguished from P. intermedia (which occupies swamp and marsh habitats in the Mississippi Valley and westward) by uppermost leaves infrequently widest at base of blade; flowering calyx tube 3.5-6 mm long; base of plant rarely conspicuously swollen; length divided by width of fruiting calyx tube 0.8 to 1.5, rarely 2.
