[Kayin State] • Nat-toung, C. Parish s. n. [young fl.] (K, K 000639732, image!).Description.Evergreen shrubs, epiphytic, 1–2 m tall. Twigs reddish brown when young, becoming grayish brown when older, terete, glabrous, without or with very sparse lenticels. Buds ovoid-conical, ca. 7 mm long, ca. 3.5 mm wide; bud scales ca. 5 mm long, triangular, apex acuminate, glabrous, caducous. Leaves alternate, pseudowhorled, 3–8 per whorl. Petiole subsessile, light green, glabrous and pruinose. Leaf blades leathery, elliptic to oblong-lanceolate, 7.5–13 × 2.5–4 cm, length: width 3–3.5, base narrowly obtuse or subcordate, margin entire, apex acuminate to shortly caudate, glabrous on both sides; midvein raised on both sides, more so abaxially; lateral veins 10–16 pairs, anastomosing near the margin, raised on both sides; veinlets conspicuous and raised on both sides. Inflorescences racemose, axillary, (10) 17–27 - flowered; rachis 6–11 cm long, pink or purplish red, rarely greenish, angular, pruinose, flowers secund; bracts lanceolate, ca. 2.5 mm long, caducous; bracteoles linear-lanceolate, ca. 1.5 mm long, inserted at the base of pedicel, caducous; pedicels expanded upwards, clavate to obconical, 0.7–1.5 cm long, pink or purplish red, rarely greenish, pruinose, articulated with calyx. Calyx tube cupulate, 1.7–2.5 mm long, purplish red or purple, rarely greenish, glabrous and pruinose; calyx limb shortly campanulate, ca. 2.2 mm long, pink or purplish red, rarely yellowish green, lobed less than 1 / 2 to base; lobes broadly triangular, apex acute, with a terminal gland, 0.5–1 mm long. Corolla white-pinkish or pinkish, turning to purplish red later; tubular-urceolate, 7–9 mm long, glabrous externally and internally; lobes reflexed, broadly triangular, ca. 1 mm long, apex obtuse. Stamens 10, ca. 7.5 mm long; filaments flat, 2–3.5 mm long, lower half nearly glabrous, upper half pubescent, more so at the apex; anthers ca. 5 mm long; thecae 2–3 mm long; tubules almost as long as thecae, opening by terminal short introrse slits ca. 1 mm long at the apex, with 2 small erect spurs at the middle abaxially, spurs ca. 0.5 mm long. Ovary inferior, pseudo- 10 - locular, each locule with several ovules; disc ca. 3 mm in diam., glabrous; style ca. 8.5 mm long, exserted ca. 1 mm from the connate anther tubules, glabrous, slightly constricted at the joint with stigma, stigma truncate. Infructescence rachis 8–15 cm long, glabrous; fruit pedicel purplish-red, pruinose. Fruit globose, 4–6 mm in diam., young fruit yellowish green, purple-black at maturity, glabrous, pruinose, calyx lobes persistent.Chinese name.红梗越橘 (Chinese pinyin: hóng g&ecaron;ng yuè jú).Distribution and habitat.This species is distributed in Southwest China (Southwest Yunnan), East Myanmar (Kachin State, Kayin State, Mon State, and Shan State), and Northwest Thailand (Chiang Mai and Tak) (Sleumer 1941; Watthana 2015) (Fig. 4). This species is usually epiphytic on trees in evergreen broad-leaved forests or along riversides at elevations of 1400–2500 m.Phenology.Flowering and fruiting from February to June.Conservation status.Based on specimen records, more than 20 locations of V. ardisioides have been recorded, and its distribution range covers a relatively large area across China, Myanmar, and Thailand, with an expected extent of occurrence (EOO) of ca. 280,000 km 2. This species is not economically valuable, and no evidence of severe population decline has been observed. Therefore, the conservation status of this species is assessed as Least Concern (LC) (IUCN Standards and Petitions Committee 2024).Taxonomic notes.The types, including paratypes, of V. rubescens are completely consistent with those of typical V. ardisioides in both key vegetative and reproductive characters, such as 5–7 pseudo-whorled leaves with subsessile petioles, leathery oblong-lanceolate leaf blades with narrowly obtuse bases, entire margins, and acuminate apices, midveins raised on both sides, lateral veins 10–12 pairs, anastomosing near the margin and raised on both sides, axillary racemose inflorescences with many secund flowers and purplish-red angular rachises, clavate and purplish-red pedicels, cupulate calyx tubes, triangular calyx lobes, ovoid-conical floral buds, and tubules nearly as long as thecae and with two short spurs at the middle abaxially. Therefore, V. rubescens should be treated as a synonym of V. ardisioides.Additional specimens examined.China.
