J. Gui & X. J. He 2020	<div><p>Tongoloa arguta L.J.Gui &amp; X.J.He sp. nov. Figs 2, 3, Table 2</p><p>Type.</p><p>China. Sichuan: Kangding, Zheduoshan Pass, 4300 m alt., 30°4'N, 101°48'E, 26 Sep 2019, Lingjian Gui GLJ19092601 (holotype: SZ).</p><p>Diagnosis.</p><p>Tongoloa arguta sp. nov. is morphologically similar to T. silaifolia . However, the new species can be distinguished from the latter by its short stems (10-50 cm), while T. silaifolia has longer ones (28-60 cm); The ultimate segments of the lower leaf of T. arguta are acute and short (1-4 mm), while those of T. silaifolia are linear and longer (5-18 mm). The umbels of T. arguta have 3-8 rays, which are significantly less than those of T. silaifolia (8-22).</p><p>Description.</p><p>Plants 10-50 cm. Root usually long-conic. Stem thinly ribbed, glabrous, purplish to green, branched. Leaf sheaths inflated, membranous; blade triangular in outline, 3-5 × 2-3.5 cm, 2-3-ternate/pinnate; ultimate segments lanceolate, 1-4 × 1-2 mm, apex acute. Umbels terminal or lateral; bracts often absent or sometimes 1, leaf-like, ca. 2-4 × 1 cm, bracteoles absent; rays 3-8; umbellules 13-25-flowered. Calyx teeth minute; petals obovate, white to purple, apex obtuse; stylopodium depressed, dark purple; styles short, reflexed. Fruit broadly ovoid, ca. 2 × 1.7 mm, base cordate; ribs 5, filiform; vittae 3 in each furrow, ca. 4 on commissure. Ventral surface of endosperm slightly concave to plane.</p><p>Etymology.</p><p>The species epithet " arguta " was given to describe the acute tips of the ultimate segments of leaves.</p><p>Phenology.</p><p>The species was observed flowering from August to September and fruiting from September to October.</p><p>Distribution and habitat.</p><p>Tongoloa arguta is distributed from Sichuan (Kangding, Yajing) to Yunnan (Deqin, Shangri-la) in south-western China. It grows in alpine bushes and meadow s from 4000 m up to 4500 m alt.</p><p>Additional specimens examined.</p><p>China.

We categorise T. arguta as Near Threatened (NT), according to IUCN (2019).</p></div>	https://treatment.plazi.org/id/EBC931842E95552FA3A15903F41598E5	Public Domain	No known copyright restrictions apply.
