F29F8EC4251753BB8FCAD46A89509E9F.taxon	diagnosis	Diagnosis. Raphiocarpus discolor is morphologically similar to R. bicallosus, but it differs from the latter in its leaf blade adaxially densely white puberulent, abaxially nearly glabrous (vs. sparsely hispid adaxially and abaxially); prophylls absent (vs. present); calyx ca. 4 × 1 mm (vs. 5 – 6 × 2 – 3 mm), outside pubescent (vs. outside glandular pubescent); corolla tube outside yellow to brownish-yellow externally with several indistinct longitudinal yellowish-brown stripes (vs. tube outside yellow to orange-yellow), inside purplish-red to purplish-brown, glabrous, with two bosses inside the corolla tube placed at the base of the abaxial lobe (vs. inside yellow with more or less dense brown purple spots, hairy bosses inside the corolla tube placed at the base of the abaxial lobe); staminode ca. 6 mm long (vs. ca. 4 mm long); capsule in size 35 – 39 × ca. 2 mm (vs. 50 – 60 × ca. 3 mm) (Table 1), although there are differences between them, these distinctions remain consistently stable.	en	Qian, Xiao-Mao, Fu, Jia-Xin, Ji, Ling-Bo, Tang, Bo, Xin, Zi-Bing, Wen, Fang (2025): Raphiocarpus discolor (Gesneriaceae), a new species from Guangdong, China.

Stem erect or prostrate at base, slightly lignified, commonly forming extremely elongated and horizontal creeping stolons at the base of stems along the ground and rooting at the nodes or the tip, and giving rise to a new plant. Leaves opposite, often clustered at the stem tip, petiolate; petiole 1 – 3.7 cm long, ca. 8 mm in diameter, green to brown, densely white pubescent. Leaf blades narrowly ovate to elliptical, each pair unequal, rarely equal, with varying degrees of bilateral asymmetry, 3.3 – 10.1 × 1.7 – 5.1 cm, both surfaces green, adaxially densely white puberulent, abaxially almost glabrous, base cuneate, margin numerously dentate, apex acute to acuminate; lateral veins 5 – 6 on each side of midrib, adaxially inconspicuous, abaxially prominent. Inflorescence cymose, axillary or subterminal dichasium, 1 – 2 - flowered per cyme; all axes white puberulent; peduncle 1.5 – 6.0 cm long, ca. 8 mm in diameter, dark green, white pubescent; bracts 2, opposite, pale green to purplish adaxially and abaxially, narrowly ovate to lanceolate, ca. 2 mm long, white pubescent, margin entire, apex acuminate; petiole 4 – 14 mm long, densely white pubescent. Calyx with 5 - parted to nearly base, lobes, outside purplish-red to reddish-brown, inside pale green to purplish-red, narrowly ovate to lanceolate, ca. 4 mm long, ca. 1 mm wide at the widest, apex acuminate, margin entire, outside vertically pubescent, inside glabrous. Corolla tube yellow to brownish-yellow externally with several indistinct longitudinal yellowish-brown stripes, purplish-red to purplish-brown internally, limb 2 - lipped, upper and lower lips externally and internally deep purplish-brown to deep purplish-black, the color of the corolla tube mouth fading downward to the midpoint of the tube, gradually deepening toward the base to purplish-black, but yellow at the 1 / 6 position from the base to the mouth; tube funnel-shaped, 3.2 – 3.7 cm long, ca. 4 mm in diameter at the base, distinctly narrowing and slightly curved from the base to the 1 / 3 point of the tube, with a prominent saccate swelling at the 2 / 3 point from the base, mouth 8 – 13 mm in diameter, outside vertically glandular puberulent, inside glabrous, with two bosses inside the corolla tube placed at the base of the abaxial lobe; corolla bilabiate; upper lip 2 - lobed to the middle, 7 – 8 × 6 – 7 mm, lobes nearly equal, nearly semicircular; lower lip 3 - lobed, lobes unequal, middle lobe 5 – 6 × 5 – 7 mm, rounded, apex emarginate, lateral lobes 4 – 5 × 3 – 6 mm, apex obtuse, slightly oblique, colored purplish-brown to violet-brown, with pinkish-purple striations along the midvein of each lobe. Stamens 4, in 2 pairs, each pair coherent at their apices, anther thecae confluent; filaments glabrous, pale yellow to purplish-red, adaxial pair ca. 1.1 cm long, adnate to the corolla tube ca. 1.5 cm above the base, abaxial pair ca. 2.2 cm long, adnate to the corolla tube ca. 2.1 cm above the base; anthers reniform constricted at the middle, ca. 1 mm long, ca. 1 mm wide, white to pale yellow, glabrous; staminode 1, clavate, ca. 6 mm long, adnate to the corolla tube ca. 2.1 cm above the base, glabrous, white to purplish-red. Disc pale yellowish, annular, obscurely 5 - lobed, 1.5 – 2 mm tall, glabrous. Pistil 3.6 – 3.9 cm long; ovary linear, glabrous, 2.1 – 2.5 cm long, ca. 1 mm in diameter; style linear, 1.2 – 1.4 cm long, ca. 2 mm in diameter, sparsely glandular puberulent, ca. 1 mm in diameter; stigmas 2, equal, undivided, lobes lipped to ligulate. Capsule green when young, glabrous, 3.5 – 4.9 cm long, ca. 2 mm in diameter, linear, almost straight, net twisted, loculicidally dehiscing from the apex to the base when mature.	en	Qian, Xiao-Mao, Fu, Jia-Xin, Ji, Ling-Bo, Tang, Bo, Xin, Zi-Bing, Wen, Fang (2025): Raphiocarpus discolor (Gesneriaceae), a new species from Guangdong, China.

F29F8EC4251753BB8FCAD46A89509E9F.taxon	etymology	Etymology. The specific epithet ‘ discolor ’ is derived from the Latin ‘ dis- ’ (meaning ‘ different’) and ‘ - color’ (meaning ‘ color’), referring to the color differences in different parts of the corolla.	en	Qian, Xiao-Mao, Fu, Jia-Xin, Ji, Ling-Bo, Tang, Bo, Xin, Zi-Bing, Wen, Fang (2025): Raphiocarpus discolor (Gesneriaceae), a new species from Guangdong, China.

F29F8EC4251753BB8FCAD46A89509E9F.taxon	distribution	Distribution and habitat. The new species is currently only known to be distributed in a small, gently sloping depression or valley between two hills in Xin’an Town, Huazhou City, Maoming City, Guangdong Province, China. The distribution site is a remnant of a subtropical evergreen broad-leaved forest, with the surrounding hills entirely developed into cultivation areas for eucalyptus and other economically important tree species. Raphiocarpus discolor typically grows on hills made of lateritic soil, at elevations of 200 meters, often influenced by a maritime climate, with additional continental climate influence in winter, and characterized by a highly pronounced monsoon climate. Accompanying species mainly include Geophila repens (L.) I. M. Johnst., Gardenia spp., Elatostema spp., and Pothos spp.	en	Qian, Xiao-Mao, Fu, Jia-Xin, Ji, Ling-Bo, Tang, Bo, Xin, Zi-Bing, Wen, Fang (2025): Raphiocarpus discolor (Gesneriaceae), a new species from Guangdong, China.
