description
The Himalayan grape sparrow is an upright, up to 2 meter high shrub with red-brown, bare or slightly hairy, angular shoots. The buds are red-brown, egg-shaped, with a blunt end and two or three bud scales with slightly hairy edges. Often two or three buds grow together in the axils of flowering branches. The leaves have a 1 to 1.5 centimeter long, almost bare stem. The stipules are about 6 millimeters long, ovate-lanceolate, pointed with a distantly serrated edge and almost glabrous. The leaf blade is simple, 6 to 8.5 centimeters long and 4 to 6 centimeters wide, ovate to ovate-elliptical, three-part or rarely three to five-lobed lobes, long, pointed with a rounded to heart-shaped base and a sharp double-serrated edge. Both sides are bald or the underside is slightly hairy on the nerves.

The flowers are numerous in 6 to 15.5 centimeters long, densely or loosely branched panicles with a slightly hairy stem. They have a diameter of about 4 millimeters and a slightly hairy flower stalk about 3 millimeters long. The flower cup is bell-shaped, 2 to 3 millimeters long and hairy on the outside. The sepals are triangular, about the same length as the calyx tube, slightly hairy on both sides, with entire margins with a pointed tip. The petals are white, about 2 millimeters long and obovate. 10 to 15 stamens are formed per flower . The ovary is cylindrical, glabrous, only hairy at the seams or as a whole and rarely has ten to twelve ovules from eight onwards. The follicles are cylindrical, the seeds ovate. The species blooms in July, the fruits ripen from September to October.
Distribution and ecology
The natural range extends from the temperate to the tropical climate zone of Asia and is located in the Chinese provinces of Guangxi , Guizhou , Sichuan , Xizang and Yunnan , in Bhutan, Nepal, in the Indian states of Assam and Sikkim , in Myanmar, Vietnam and on the Indonesian islands Java and Sumatra . It grows in cool, moist forests at altitudes of 1000 to 3000 meters on acidic to weakly alkaline, humus-rich, sandy-loamy to loamy, nutrient-rich soils in shady, winter-mild locations. The species is sensitive to frost.
Systematics
The Himalayan grapes spar ( Neillia thyrsiflora ) 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 David Don in 1825 .
There are two varieties :
- Neillia thyrsiflora var. Thyrsiflora with densely branched flower panicles and a bald ovary or ovary with hair only at the seams. The distribution area of the variety is in the northwest of Yunnan, in Bhutan, Sikkim, Myanmar and Nepal at altitudes of 1000 to 3000 meters.
- Neillia thyrsiflora var. Tunkinensis (JE Vidal) JE Vidal with loosely branched flower panicles and a completely hairy ovary. The distribution area is in the Chinese provinces of Guangxi, Guizhou, Sichuan, Xizang and Yunnan, in North Vietnam, Assam and Indonesia at altitudes of 1000 to 2700 meters.
