description
The Tibetan grape sparrow is a shrub up to 3 meters high with almost round, densely yellowish-brown, later reddish-brown and softly hairy shoots. The buds are egg-shaped, reddish brown with a pointed end, and three to four on the edge hairy bud scales. The leaves have a 8 to 10 millimeter long, densely hairy stem. The stipules are 4 to 8 millimeters long, lanceolate or ovate-lanceolate, hairy on both sides, pointed with a serrated edge. The leaf blade is simple, 5 to 10 centimeters long and 3 to 6 centimeters wide, ovate to oblong-elliptical, rarely triangular-ovoid, irregularly three to five-fold or clearly lobed to half of the midrib, long, pointed with a rounded or heart-shaped base and sharp double sawn edge. The underside of the leaf is hairy, the top is sparsely hairy.
The flowers are three to five in 5 to 15 centimeter long clusters with a densely hairy stem. They have a diameter of about 4 millimeters and a 3 to 4 millimeter long, densely hairy flower stalk. The flower cup is cylindrical, 5 to 6 millimeters long and densely hairy on both sides. The sepals are 2 to 3 millimeters long, triangular, shorter than the calyx tube, densely hairy on both sides, with entire margins with a pointed tip. The petals are reddish white, about 3 millimeters long and obovate. Depending bloom 15 to 20 are stamens and a cylindrical, hairy at the top ovary with five to eight formed ovules. The follicles are cylindrical, the seeds ovate. The species blooms from May to June, the fruits ripen from July to September.
Distribution and ecology
The natural range is in the Chinese provinces of Sichuan and Yunnan . It grows in cool, moist mixed forests at altitudes of 1500 to 3000 meters on well-drained, fresh to moist, acidic to neutral, sandy or gritty-humic, nutrient-rich soils in sunny to light-shaded locations. The species loves warmth and is usually frost hardy, but avoids chalky soils.
Systematics
The Tibetan grapes spar ( Neillia thibetica ) is a kind of the genus of neillia ( Nellia ) in the family of Rosaceae (Rosaceae), subfamily spiraeoideae, tribe Neillieae. The species was first described by Louis Édouard Bureau and Adrien René Franchet in 1891 .
There are two varieties :
- Neillia thibetica var. Lobata (Rehder) TTYu with ovate-lanceolate stipules with a wavy, serrate and ciliate margin and a leaf blade that is clearly lobed to half of the midrib. The distribution area of the variety is in the southwest of Sichuan and northwest of Yunnan at altitudes of about 2900 meters.
- Neillia thibetica var. Thibetica with lanceolate stipules with a serrate and ciliate margin and an irregular three- to five-fold lobed leaf blade. The distribution area is in the west of Sichuan and northwest of Yunnan in mixed forests along rivers at altitudes of 1500 to 3000 meters.
use
The Tibetan grape spar is sometimes used as an ornamental wood because of its decorative flowers .
