Pynus pyrifolia, a deciduous tree growing 10-15m high,
occurs in the mountains near human habitations. The phyllotaxis of
the leaves is alternate; blades are 6-18cm long, in the shape of an
ovate or oblong-ovate, with awn-like sharp serrations on margins,
soft down hairs at first, and get lost later. Short branch tips
emerge, and corymbs set about 5-10 white flowers about three cm in
diameter. Fruit (pomes), 2-3cm-in-diameter, spherical, matures in
yellow-brown in September-October. Bloom time: April-May. |
