Alnus pendula is
a small deciduous tree with black-brown barks. Many inhabit poor
lands in hilly to mountainous regions, branching well to grow to
2-7m in height. Leaves are alternate, 5-10cm long, 2-4cm wide,
narrow-oval-like lanceolate, upper portions tapering to points, and
bases round, with margins with fine serrations. Lateral veins
comprise 20-26 pairs, dent at surfaces, and protrude on the
backsides. Flowers are monoecious, simultaneously open with the
development of the leaves. Male inflorescences with no petioles, 1-3
in number, hang down at the end of the branches, and females with
petioles, 3-6 in number, set themselves below the males. Bloom time:
March-May. |
