Habitat
Anthropogenic (man-made or disturbed habitats), forest edges, forests
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

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.
