Tilia amurensis

The Amur lime or Amur linden, is a species of tree in the mallow or Malvaceae family, native to eastern Asia (parts of China, the Koreas, north-east Siberia in Russia). It differs from the better-known Tilia cordata in having somewhat smaller leaves, bracts and cymes. It can grow to 32 m tall.

It is an important timber tree in Russia, China and Korea.

• Bark is grey with irregular ridges developing with maturity; twigs are slender; winter buds are stout, ovate-acute, smooth, deep red, with 2 bud scales visible.
• Leaves are deciduous, simple, alternate, orbicular but with a long slender tip and a typically cordate base, 4–8 cm long and 4–7 cm across, lower surface pale green or glaucous, and with large persistent tufts of reddish hair under the vein axils; teeth have prominent sharp-pointed tips 0.4–1.2 mm long.
• A whitish-green leaf-like bract 4–10 cm long and 0.5–1.5 cm across is attached for half its length at the base of the cyme; flowers are hermaphroditic (have both male and female parts), drooping, widely branched, with 10–30 flowers on long pedicels.
