Saussurea obvallata (DC.) Edgeworth
- genus Saussurea DC.
Herbs, perennial, 16-60 cm tall. Rhizomes thick, neck densely covered with brown fibrous lacerate residue of petioles. Stems erect, pubescent or glabrous. Basal leaves with to 8 cm petiole; leaf blade narrowly elliptic, oblong, or ovate, 7-20 cm long, 3-6 cm wide, glandular hairy, base cuneate, margin serrulate, apex obtuse. Stem leaves sessile, similar to basal leaves but gradually smaller towards stem apex. Uppermost stem leaves surrounding inflorescence, yellow, narrowly elliptic to ovate-oblong, to 16 cm long, 7 cm wide, membranous, pubescent or glandular hairy, margin serrulate, apex obtuse. Inflorescences terminal on stem, hemispherical. Capitula 6-15, pedunculate or not. Involucre hemispherical, 1-1.5 cm in diameter. Phyllaries in 4 rows, abaxially pubescent and glandular hairy, margin blackish purple, apex acute; outer phyllaries ovate; middle phyllaries elliptic; inner phyllaries linear. Pappus dark brown, in 2 rows; outer pappus ca. 5 mm, scabrous; inner pappus ca. 1.2 mm. Florets bluish purple, ca. 1.8 cm, tube ca. 8 mm, limb ca. 1 cm. Achene oblong, ca. 5 mm.
Saussurea obvallata is close relative of Saussurea wettsteiniana, but differs from the latter in subtending leaves to 11 cm (vs. no more than 7 cm), capitula 6-15 (vs. 1-3), sessile (vs. with short peduncles), straight (pendent), phyllaries abaxially glandular hairy (vs. villous).
The chromosomal number of Saussurea obvallata is 2n = 32 (Gupta and Gill, 1989; Gupta et al., 1989; Amano and Ohba, 2000).
