South-Eastern Tibet, Kongbo province, Kyabden, Nyang Chu, 10.000 ft, N 29°40’, E 94°16’, 31. 08. 1938, Ludlow, Sherriff, Taylor 6201 (holotype BM!, isotype E!). Recognition. <i>M. microloba</i> is most similar to <i>M. achilleifolia</i> but can be distinguished by their basal leaves (terminal leaflets curved vs. almost straight), rays (4–6 vs. 10–14), bracts (short linear vs. leaf-like) and fruit length (2–3 mm vs. 3–4 mm). It is also similar to the closely related species <i>M. delavayi</i>, but can be also distinguished by its basal leaves (terminal leaflets 1–6 × 0.5–3 mm vs. 3–10 × 1–4 mm) (Table 3). Description. Herbs perennial. Plants 15–65 cm. Taproot fusiform several branched with cyclic striae. Stems striped. Basal petioles 0.5–6 cm, sheaths short, membranous, perished leaf sheaths flaky or fibrous; basal blade 2–4- pinnate, 4–20 × 2–9 cm; pinnae 6–8 pairs, lower pinnae long-petiolulate; terminal leaflets ovate-linear or linear, curved, 1–6 × 0.5–3 mm. Leaves reduced upwards, uppermost small, shortly petiolate or sessile. Umbels 2–5 cm across; peduncles 4–16 cm; rays 4–6, 1– 3 cm, spreading; Bracts 1–3, subulate or linear, 1–2 × 0.5 mm, with minute white edge; bracteoles 4–6, linear-subulate, ca. 1 mm, with minute white edge; pedicels unequal. Petals white, broadly ovoid, apex inflexed, medial rib obvious, ca. 0.8 × 0.6 mm. Stylopodium short-conic. Fruit oblong-ovate, mericarp ca. 2.5 × 1.5 mm, commissure ca. 1 mm in width; calyx teeth subulate, 0.25–0.35 mm; ribs filiform, 2–3 vallecular vittae, 4 commissural vittae. Phenology. Found flowering in July–August, fruiting in August–September. Distribution and habitat. China, Xizang, Nyingchi, near Niyang Qu. It grows in forest edge of mountain slopes, grassy places.
