Pinus maximinoi
Pinus maximinoi
Pinus maximinoi is a flowering plant in the genus pines ( Pinus ). Your name honors the Mexican botanist Maximino Martinez ( 1888-1964 ). This species is native from Mexico to Nicaragua.
Features
Pinus maximinoi a tree, plant height of 20 to 35 meters, with a trunk diameter of up to 100 cm is reached and has a straight shaft. Old trees have horizontal branches that form a dense, rounded crown. Young trees have an open, pyramidal crown, the branches are in regular whorls. The bark is gray-brown in old trees, rough and divided by horizontal and vertical cracks in large plates. In the upper stem region, the bark is smooth and gray -brown. In young trees the bark is just as smooth and gray -brown. The branches are long, slender, flexible, often somewhat pendulous.
The needle leaves are in clusters on short shoots to fifth; the sheaths are subject to change, pale brown and 12 to 18 mm long. The hanging needle leaves are very slender and 15 to 28 cm long. The margin is finely serrated. There are three resin canals present, rarely two or four. The hypodermis is sufficient in some places deep into Chlorenchym. There are two adjoining but separate vascular bundles.
The male flowers are near the proximal end of the new main shoots. They are cylindrical, 30-40 mm long and 5-8 mm wide, pink-brown and are surrounded by brown, lanceolate bracts subulat.
The female cones are subterminal and are oblong; the cone scales are thick and end in a small, early falling mandrel. They are in groups of 4 to 5 at a scaly, long stem. The mature cones are red-brown, long - ovoid and asymmetric. They are 5 to 8 cm long. They are three or four of slender, 10-15 mm long stalks. The maturation takes place in winter; the cones open to mature and fall off soon after that, the stem remains on the pin. The cone scales are thin and flexible. The apophysis is keeled flat and slightly cross, the umbo is small, sometimes slightly raised with a small, early falling mandrel.
The seeds are small, 5-7 mm long and dark brown to almost black. The seed wing is 16 to 20 mm long and light yellow-brown. The number of cotyledons is usually seven or eight (rarely six).
The wood is rather soft and soft, but firm. The sapwood is pale yellow white and the heartwood slightly darker. It is used as lumber, locally also as firewood and for construction of houses.
Occurrence
Pinus maximinoi is quite prevalent in Mexico and Central America. It also occurs in Guatemala, El Salvador, Honduras and northern Nicaragua.
This species grows at altitudes 600-2400 m, but grows best between 800 and 1500 m. The best locations are semi - tropical with well water rapid soils and annual rainfall of 1000-2000 m. It grows along with Pinus pseudostrobus, Pinus douglasiana and other pines.
