Discussion

Plants of Rhamnus lanceolata with hirtellous-pubescent stems and leaves (subsp. lanceolata if given formal recognition; the type from Tennessee) are more restricted in distribution than glabrous plants, but the distinction often seems arbitrary. Densely hairy and glabrous plants both occur in Alabama and Tennessee. Plants with sparsely hairy leaves occur commonly in Kentucky and Illinois, rarely in Missouri and Iowa, and the density of the vestiture is variable.
