2.  Tilia cordata P. Mill. E

small-leaved linden. CT, MA, ME, RI, VT. Roadsides, forest fragments and edges, areas of habitation.

2×4. Tilia cordata × Tilia platyphyllos → Tilia ×‌vulgaris Hayne is a planted linden hybrid that sometimes escapes cultivation. It is known from CT, MA, ME, RI. It is recognized by its leaf blades 6–10 cm long with prominent tertiary veins (the tertiary veins of T. cordata are faint), the blades abaxially glabrous except for tufts of white hairs in the axils of veins. The pendent 
cymes have 5–10 flowers and the fruits are 6.7–7.9 mm long with smooth or only slightly ribbed pericarps.

Native to North America?

No

Sometimes confused with

Tilia americana:
leaf blades 7-20 cm long and fruit mostly 6-8 mm long (vs. T. cordata, with leaf blades mostly 3-9 cm long and fruit 4.5-6.6 mm long).
Tilia platyphyllos:
fruit 8–10 mm long, with a woody pericarp that is conspicuously 5-ribbed, and cymes pendent, with 2–5 flowers (vs. T. cordata, with fruit 4.5–6.6 mm long, with a membranaceous pericarp that is weakly, if at all, ribbed, and cymes obliquely erect, with 4–15 flowers).
