Characteristics

Erect perennial herb, up to 450 mm high. Main stem simple to two-branched at base, erect, 2-4 mm thick, produced into scape, hirsute, sparsely leafy, subbasally many-branched (without the main stem branching). Erect perennial herb, up to 450 mm high. Main stem simple to two-branched at base, erect, 2-4 mm thick, produced into scape, hirsute, sparsely leafy, subbasally many-branched (without the main stem branching). Secondary branches subbasal, numerous, simple to subsimple, densely leafy, hirsute, ascending, terminating at subequal height. Leaves up to 20 mm long, moderately densely hirsute, the upper (younger) simple, the lower (older) imparipinnatisect, up to trijugate, main segments cuneate to linear, terminal segments linear-lanceolate; margins involute; apices glabrous, sclerotic, often brown. Axillary leaves common in axils of pinnatisect leaves, simple, filiform to linear-lanceolate, one-or two paired, the second (younger) pair always shorter. Inflorescence simple. Scape solitary, produced from main stem, hirsute, very sparsely leafy. Head solitary, radiate, up to 25 mm diam. excluding rays, more than 100-flowered. Involucral bracts 3-4-seriate, subequal, narrowly lanceolate, rufous hirsute on outer surface, glabrous on inner surface, 1-1.5 mm wide, 6-9 mm long, the outer narrower than the inner. Receptacle nude. Ray florets 25-30, female but sterile. Rays white, much longer than bracts, simple to deeply trilobate, sparsely pubescent, with superficial bicellular glands; cells of the upper surface shortly (dumpy) botuliform, radially lightly striate (fingerprinted); tube short, about 1 mm long. Androecium absent. Style 1.7-1.8 x 0.16-0.23 mm, two-branched towards apex; branches 0.46-0.54 mm long, truncate; base only slightly thickened. Nectary absent. Ovary not well developed, with superficial bicellular glands. Ovule reduced. Pappus absent. Disc florets bisexual, fertile, more than 100, 4.2-5.7 mm long. Corolla yellow, 2.5-3.0 mm long, with superficial bicellular glands, narrowly funnel shaped to cylindrical, tetralobate; lobes 0.4-0.5 mm long, spreading when mature; margins thickened, with protruding elongated cells, with thickened and longitudinally striate (fingerprinted) walls; cells of the inner surface transversely striate (fingerprinted). Stamens 4, attached to corolla tube above base but below middle. Filament short, 0.44-0.55 mm long; filament collar 0.29-0.33 x 0.10-0.11 mm, cells 6-8-seriate in longitudinal section; anther thecae 0.96-1.11 mm long; apical appendage oblong, obtuse to truncate, 0.15-0.20 x 0.19-0.23 mm; tails 0.04-0.10 mm long. Style around 2.6 x 0.19-0.21 mm, two-branched towards apex, branches 0.63-0.66 mm long, truncate. Stylopodium 0.34-0.46 mm wide, 0.17-0.23 mm high; cells with thick walls. Nectary 0.29-0.32 mm wide, 0.10-0.11 mm high, under stylopodium. Ovary 1.7-2.7 mm long, four-ribbed, flattened when mature, marginal wings narrow but broadened above, superficial glands, bicellular to shortly biseriate (up to three cells high). Pappus absent.
