Morphological characteristics of Pinus massoniana Lamb

Pinus massoniana Lamb is a tree with a height of 45 meters and a diameter of 1.5 meters at breast height; the bark is reddish brown, the lower part is grayish brown, cracked into irregular scaly pieces. The branches of pinus massoniana lamb are spread out or obliquely, and the crown is wide and tower-shaped or umbrella-shaped. The branches grow once a year, but in southern Guangdong they usually grow two rounds. They are pale yellowish brown, without white powder, rare white powder. Winter buds are oval cylindrical Shaped or cylindrical, brown, pointed at the top, with filiform edges on the bud scales, pointed at the apex or into a pointed long point, slightly recurved. Needles are with 2 needles in one bunch, thin 3 needles in one bunch, 12-20 cm long, soft, slightly twisted, with stomatal lines on both sides, and fine serrations on the edges; monotypes of cells in the subcutaneous layer of the transverse section. The first layer is continuous, and the second layer is composed of individual cells intermittently arranged. There are about 4-8 resin channels, which grow on the back side or 2 sides on the ventral surface. The leaf sheaths are brown at first, and then gradually become gray-black and persist. Male cones are reddish-brown, cylindrical, curved, 1-1.5 cm long, clustered in the lower bract axils of new branches, spike-like; female cones are solitary or 2-4 clustered near the top of new branches, light purple red , Small annual cones are round or ovoid, about 2 cm in diameter, brown or purple-brown, the scales of the upper bead scale have short spines upright, and the scales of the lower bead scales are flat and blunt without spines. Cones are ovoid or conical ovoid, 4-7 cm long, 2.5-4 cm in diameter, short stalks, drooping, green before maturity, chestnut brown when ripe, falling off one after another. Middle seed scales are nearly rectangular and obovate , or nearly rectangular, about 3 cm long; scale shield rhombus, slightly raised or flat, slightly obvious transverse ridges, scale umbilicus slightly concave, no thorns, born in a dry environment often have very short spines; seeds long ovoid, 4-6 mm long, 2-2.7 cm long wing; 5-8 cotyledons; 1.2-2.4 cm long; primary leaves are strip-shaped, 2.5-3.6 cm long, with sparse spines on the edge of the leaf. Flowering period is from April to May, and the cones mature are from October to December the following year.
