morphological character

Lavender is a semi-shrub or dwarf shrub, branched, stellate tomentose and dense in tender part; The old branches are grayish brown or dark brown, the cortex is stripped in strips, the flower branches are long and the regenerated branches are short. Leaves linear or lanceolate. The leaves on the flower branches are big and far, 3-5 cm long and 0.3-0.5 cm wide. They are covered with dense or sparse gray stellate villi, which are gray or olive green when dry. The leaves on the regenerated branches are small and clustered, with a length of no more than 1.7 cm and a width of about 0.2 cm. They are densely covered with gray stellate fluff, which is gray when dry. ?

A verticillate plant usually has 6- 10 flowers, most of which are clustered into discontinuous or nearly continuous spikes at the top of branches. The spike is about 3(5) cm long, the peduncle is about 3 times as long as the inflorescence itself, and it is densely covered with stellate villi. Bracts rhombic-ovoid, apex acuminate into subulate, with 5-7 veins, usually rusty when dry, stellate tomentose, bracteoles inconspicuous; Flowers with short peduncle, blue, densely covered with gray, branched or unbranched villi. Calyx ovoid tubular or nearly tubular, 4-5 mm long, 13 veins, nearly hairless inside, 2-lipped, wide and long upper lip 1 teeth, short lower lip 4 teeth, equal and obvious teeth. Corolla is about twice as long as calyx, with 13 veins. The outer surface is covered with the same hair as the calyx, but the base is almost hairless. The inner surface is covered with glandular hairs at the throat and edge, with a hair ring in the middle. The brim is 2-lipped, the upper lip is straight, 2-lobed, and the lobes are large and round, slightly overlapping each other. Lower lip spreading, 3-lobed, lobes small. Stamens 4, inserted on trichomes, not prominent, long front pair, flat filaments, glabrous, anthers hairy. Style hairy, apex compressed, ovoid. Disk 4-lobed, lobes opposite to ovary lobes. ?

Nutlets 4, elliptic, smooth and shiny, with a basal surface. Flowers bloom in June. The whole plant has a faint aroma with a slight woody sweetness. Because the villi on flowers, leaves and stems contain oil glands, they will burst when touched lightly and release fragrance.
