Description

Fortunes Kopfeibe grows as evergreen, can achieve multi-stemmed shrub or small tree stature heights of up to 20 meters and diameter at breast height of up to 20 centimeters. The open crown is usually slightly rounded shape. The branches are in the cross-sectional shape of an oval, triangular or approximately rectangular in shape. The strain has a dark, reddish-brown bark that peels off in strips.

The small buds are covered with pointed, glossy red-brown scaly leaves. The soft but leathery and pliable needles straight shape with a length from 1.5 to 12.5 centimeters and a width of 1.5 to 5 millimeters to linear-lanceolate. You are at a 0.5 to 2 mm long stalk and go more or less straight from the branches off. The asymmetric base of the needles is wedge-shaped to flat tapered, while the tip is pointed. The needle edges are flat, and slightly twisted when dry needles. The needle top is colored glossy dark green and at the needle base you will find 13 to 24 Stomatabänder.

The heyday of the kind is from April to May, and the seeds ripen from June to October. The male cones are spherical shaped with a diameter of 6-10 mm and are occasionally one to five millimeters long stem. They are in groups of six to 14 and each contain six to 16 Mikrosporophylle with three to four pollen sacs. The female cones have a 3 to 12 mm long stem and stand together in groups of three to six. They are from a 1.4 to 2.5 cm long and 0.9 to 1.5 inches wide seed coat ( aril ) surrounding it. This is initially yellow or green and turns to maturity towards purple. On its surface are found, depending on the subspecies, numerous, only vaguely recognizable stripes or clearly visible longitudinal ridges. The elliptical seeds are 1.3 to 2.4 inches long and 0.7 to 1.4 inches thick.

The chromosome number is 2n = 24

  • Cephalotaxus fortunei subsp. alpina ( H.L. Li) Silba. It occurs in southern Gansu and northern Shaanxi. Furthermore, they are found in northern and western Sichuan and northwest Yunnan in the mountains on the border of Kham. Your male cones are not or only very shortly stalked and her seed coat has clearly pronounced longitudinal ridges. A synonym is Cephalotaxus alpina (HL Li) LK Fu
  • Cephalotaxus fortunei subsp. fortunei is the nominate form and occurs in the remaining area of ​​distribution. Your male cones are stalked and her seed coat has many, only dimly visible streaks.
