Pynus pyrifolia, a
deciduous tree growing to 10-15m in height, 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 corymbs that set about
5-10 about 3cm-in-diameter white flowers. Fruit (pomes),
2-3cm-in-diameter, spherical, matures in yellow-brown in
September-October. Bloom time: April-May. |
