Status of endangered species. Posted on the river disappears, Fujian Department of regions, special habitats, natural regeneration and, with the destruction of the environment changing vegetation, plants grown less and less. Morphological characteristics Jonsson or small evergreen shrubs often much branched; bark brown, flaking into the old; branches whorled or opposite, conduct or drooping twigs, green shoots, 2-3 year-old worker brown, Jiang; winter buds with few decussate shedding of bud scales. Leaves opposite, fitted to the two, hard, linear-lanceolate shape, 3-13 cm long, 3-4 mm wide, first becoming spiny tip, base cuneate, with a short handle, light green above, and with two obvious midrib, yellowish green below, there are two sides over the green with narrow white stomatal bands. Male and female plants, male cones solitary and axillary, with 4-8 rounds, each round four stamens. Oval or oblong, base decussate bracts, with short; female cones pairs born in leaves, each with two pairs of decussate bracts and a small lateral bracts, with short Terrier; ovule solitary, erect, just a ball of flower development.

Longleaf Introduction Longleaf Genus: Taxaceae Alias: Characteristics: A small evergreen tree or shrub often much branched; bark brown, flat, into the old flaking; branches whorled or opposite, conduct or drooping twigs, green shoots, 2-3 years old workers brown, river Ze; winter buds with few decussate shedding of bud scales. Leaves opposite, fitted to the two, hard, linear-lanceolate, shape, 3-13 cm long, 3-4 mm wide, first becoming spiny tip, base cuneate, with a short handle, top light green, micro, and with two obvious midrib, yellowish green below, there are two sides over the green with narrow white stomatal bands. Male and female plants, male cones solitary and axillary, with 4-8 rounds, each round four stamens. Oval or oblong, base decussate bracts, with short; female cones pairs born in leaves, each with two pairs of decussate bracts and a small lateral bracts, with short Terrier; ovule solitary, erect, just a ball of flower development. All seeds are fleshy aril the bag, pour oval, 2-3 cm long, red and yellow when ripe, is white; embryo apparently inward deep wrinkles. Distribution and habits: Distribution Tonglu, Jiande, southern Xianju, Songyang, suichang, Jinyun, Lishui, Longquan, Qingyuan, cloud and, Yongjia, Fujian Pucheng north and northwest taining other places, altitude 250-900 m zone. Distribution area in the eastern subtropical. East wind due to the impact of interpersonal climate characterized by high summer temperatures, rainy winter is cold, the annual basic moist. The annual average temperature of 17-20, the most extreme temperatures up to 40, extreme minimum temperature of -9.9, 1350-1600 mm annual rainfall, relative humidity of 80%, mostly rock granite, rhyolite, limestone and red sandstone, soil Mountain yellow or red soil f soil, strongly acidic, PH value 5-4.2, organic matter content above 10%. Can often grow in steep canyons or deep base bare evergreen broadleaf forest on both sides of the steep shady or stream or secondary thickets. And must be well developed lateral roots, root cortex has hypertrophy, storage capability; Fujian Ning very long narrow leaves buds usually grows to a certain time they stop growing, often sprouted several branches from the base, so mostly clustered in adult trees , the ability of a temporary drought. 5-10 years old saplings will generally flowering and fruiting, flowering from March to April, the seeds mature in October next year. Propagation and cultivation: Seed propagation. Postharvest storage for the winter with warm sand or direct seeding, germination began in the spring of the second year, the germination rate of about 0.5-1%; thin seedlings should take shade canopy shade, a year seedlings up to 10-13 cm high, when the seedlings The leaf of 15-20 films can be transplanted. Application: Endangered species. Jackii remnants of ancient species, habitat peculiar form of special significance are the more important is the study of the classification of flora Quaternary glacial climate and so on. Photo:
