95C4A7A615715E1D8F36ECC53A6B99F2.taxon	diagnosis	Diagnosis. Eumachia brevipedunculata is morphologically similar to E. straminea, but can be distinguished by its smaller stipules (ca. 2 mm vs. 2.5 – 6 mm long), shorter petioles (0.5 – 1.2 cm vs. 1 – 2 cm long), smaller leaf blades (5 – 18 × 2 – 8 cm vs. 10 – 25 × 4 – 10 cm); smaller inflorescences (1 – 1.2 × 1 – 1.2 cm vs. 1 – 4 × 1 – 2.5 cm) without developed axes (vs. axes 3 – 10 mm long), shorter peduncles (up to 0.5 cm vs. 1 – 1.5 cm long), shorter pedicels (up to 1.5 mm vs. 1.5 – 4 mm long); longer calyx lobes (0.5 – 1.5 mm vs. up to 0.5 mm long), linear-lanceolate to narrowly ligulate calyx lobes (vs. denticulate), shorter corolla tubes (1 – 1.5 mm vs. 1.5 – 2 mm long), yellowish-green corolla (vs. white to cream) and shorter anthers (ca. 0.5 mm vs. ca. 1 mm long).	en	Quan, Dong-Li, Tan, Yun-Hong (2025): Eumachia brevipedunculata (Rubiaceae, Palicoureeae), a new species from Yunnan, China.

95C4A7A615715E1D8F36ECC53A6B99F2.taxon	description	Description. Shrubs, 0.5 – 2.5 m tall, branched; stems terete, glabrous; internodes flattened. Leaves opposite, without domatia; petiole 0.5 – 1.2 cm long, glabrous; leaf blade concavo-convex, elliptic to lanceolate, 5 – 18 × 2 – 8 cm, green, often paler abaxially, adaxially somewhat shiny in life, drying papery, glabrous on both surfaces, base cuneate to attenuate, apex acute to acuminate, margins flat or slightly undulant, usually thinly revolute; secondary veins 6 – 8 at each side of the mid-rib, free or forming a weakly- to a well-developed looping submarginal vein, adaxially costa thickened to prominent and secondary veins sometimes prominent, abaxially costa and secondary veins prominent, remaining venation flat; stipules persistent or falling by fragmentation with persistent portion becoming indurated and yellow to ochre, interpetiolar to shortly fused around stem or forming a sheath, ca. 2 mm long, triangular to ovate, with 2 costae bearing 2 lobes, lobed to 1 / 4 – 1 / 2, lobes subulate with glandular tip, abaxially glabrous, adaxially at base with well-developed drying red-brown colleters. Inflorescences terminal, cymose, congested, subglobose to corymbiform, 1 – 1.2 × 1 – 1.2 cm, branched to 1 – 3 orders without developed secondary axes, generally 3 - to 15 - flowered, glabrous, subsessile to shortly pedunculate with peduncle up to 5 mm long; bracts narrowly triangular, ca. 0.5 mm long, pubescent to glabrescent outside, apex obtuse; pedicels up to 1.5 mm long. Flowers 5 - merous, rarely 4 - or 6 - merous, usually bent down, distylous; hypanthium obconic, ca. 1.5 mm long, glabrous; calyx green to brown, glabrous, limb ca. 0.5 mm long, lobes 0.5 – 1.5 mm long, lobes linear-lanceolate to narrowly ligulate, apex obtuse; corolla yellowish-green, campanulate, tube 1.5 – 2.5 mm in diameter, 1 – 1.5 mm long and slightly shorter than half the corolla length, glabrous outside, inside white villous in throat, lobes valvate in bud, ovate, 2 – 2.5 × 1 – 1.5 mm, adaxially rostrate, abaxially smooth, apex obtuse, bent inwardly; stamens glabrous, in long-styled form 1.5 – 2 mm long, slightly exserted from corolla tube, in short-styled form 2.5 – 3 mm long, completely exserted from corolla tube; anthers elliptic to oblong, obtuse, dorsifixed, ca. 0.5 mm long, always exserted from corolla tube; filaments in long-styled form 1 – 1.5 mm long, in short-styled form 2 – 2.5 mm long; stigmas 2 - lobed, lobes ca. 0.2 mm long; style erect, clavate; style and stigma in long-styled form 2 – 2.5 mm long, can exceed 1 / 2 of the corolla tube, but is never exserted from the corolla tube, in short-styled form 1.5 – 2 mm long, equal in length to or partially exserted from corolla tube; ovary inferior, 2 - celled, ovules 1 in each cell, disc glabrous. Fruit drupaceous, fleshy, ellipsoid to subglobose, 0.6 – 1 cm in diameter, stipitate, glabrous, black at maturity, not reddening, ribbed when dried, calyx lobes persistent; pyrenes 2, hemispherical, bony, dorsally convex with granulose ornamentation or 1 – 5 shallowly ribbed, ventrally plano-concave, with marginal preformed germination slits, without ethanol-soluble pigments; seeds ellipsoid to hemispherical, 4.5 – 6 × 5 – 7 mm; endosperm fleshy, non-ruminate.	en	Quan, Dong-Li, Tan, Yun-Hong (2025): Eumachia brevipedunculata (Rubiaceae, Palicoureeae), a new species from Yunnan, China.

95C4A7A615715E1D8F36ECC53A6B99F2.taxon	etymology	Etymology. The specific epithet ‘ brevipedunculata ’ refers to the new species’ distinguishing feature of reduced inflorescences with short peduncles, axes and pedicels. Its Chinese name is given as 短序肉沛木 (Pinyin: duǎn xù ròu pèi mù).	en	Quan, Dong-Li, Tan, Yun-Hong (2025): Eumachia brevipedunculata (Rubiaceae, Palicoureeae), a new species from Yunnan, China.
