Morphological characteristics/Inula viticulata

Perennial herb. The rhizome is short and thick, with solitary or a few clustered stems and buds covered with long hairs. The stem is erect, 20-70 cm high, about 2-3.5 mm in diameter at base, all spreading, with dense yellow-brown long stiff hairs with warty base at upper part, slender branches at upper part or from middle part, and denser leaves at lower part; internodes 2-4 cm long, or longer at upper part of stem.

Leaves are more or less spreading, elliptical, lanceolate or oblanceolate, with smaller leaves at the base; lower and middle leaves are 5-10 veined.

The leaf blade is 3.5-4.5 cm long and 2.5-3.5 cm wide. The lower part gradually narrows into a long petiole, the edge has shallow or obvious serrations from the middle upwards, the upper part is acute, the apex is slightly pointed, and there are warty rough hairs on both sides at the base, but the veins have long and dense hairs spreading below; the lateral veins are about 4 pairs, curved, and almost parallel to the lower leaf margin; the upper leaves are small and sessile. The inflorescence head is solitary at the branch end or a few are arranged in an umbel shape, with a diameter of 1.5-2.5 cm; the peduncle is slender. The involucre is hemispherical, 6-8 mm long; the involucre has 4-5 layers, the outer layer is slightly shorter.

The leaves are elliptic-lanceolate, the upper or apical part is leathery, covered with long rough hairs, the lower part is leathery, but the outermost layer is often longer, elliptic or linear-lanceolate, the entire leaf is elliptic, the inner layer is linear-lanceolate, the apex is purple-red, nearly membranous, with soft hairs and ciliates. The ligulate flowers are twice as long as the involucre, with white tongues, 8-9 mm long, linear-elliptical; the tubular flower corolla is 5-6.5 mm long, yellow, with pointed oval-triangular lobes; the pappus is white, slightly yellowish at the back,

Corolla about as long as tubular flowers with up to 20 rough hairs. Achenes are cylindrical, with fine grooves, 2-2.5 mm long, and covered with silky hairs. The flowering period is from July to October, and the fruiting period is from September to December.

This species has considerable variation, especially in the number and size of the capitula, the difference in length between the inner and outer bracts, the length and shape of the phyllostachys of the inner bracts, etc., which are often not completely consistent. However, judging from the fur, tongue shape, color, etc., it is still appropriate to regard it as one. This species resembles some species of the genus Aster, of which it is related only to Inula simonii, which is native to Bhutan.
