Tilia cordata

The small-leaved lime, or littleleaf linden or small-leaved linden is in the mallow or Malvaceae family and is native to much of Europe, from Britain through mainland Europe, to the Caucasus and western Asia. It can grow to about 40 m tall.

• Bark is smooth and grayish when young, firm with vertical ridges and horizontal fissures when older; crown is rounded in a formal oval shape to pyramidal; branching is upright and increases in density with age; buds are alternate, pointed egg shaped and have red scales, with no terminal buds.
• Leaves are deciduous, simple, alternate, rounded to triangular-ovate (distinctly heart-shaped), 3–8 cm long and broad, mostly hairless (unlike the related Tilia platyphyllos) except for small tufts of brown hair in the leaf vein axils.
• Flowers are small yellow-green hermaphroditic, produced in clusters of 5-11 in early summer, with a leafy yellow-green subtending bract below the flowers (unlike often being below the bract in some linden species).
• Fruit is a dry nut-like drupe 6–7 mm long and 4 mm broad containing 1–2 brown seeds, shell downy at first, becoming smooth at maturity, and not ribbed but very thin and easily cracked open.
