Plant growing as an isolated stem or clump-forming, slender, suckering freely (up to 8 suckers) and spreading in different directions, arising about 20–40 cm from the base of the parent plant, up to 150 cm, oriented vertically; sucker leaves mostly auriculate at base, without blotches on leaves of water suckers. Mature pseudostem 259–373 cm tall, 14– 18 cm in diam. at base, dark-purple green to black-green, shiny, predominantly light green with purple pigmentation, without wax, sap milky. Leaf habit semi-erect; petiole 37–87 cm, green, with sparse black purple blotches at base, petiole canal wide with erect margins, winged and clasping the pseudostem, petiole margins with red purple lines, 7–12 mm in width, quickly scarious.

Male flowers 5 to 8 per bract, arranged in a row, 6.1–7.1 cm long; compound tepals oblong-lanceolate, 4.9–6.4 × 1.6–2.8 cm long, orange-yellow with reddish pigmentation, lobes 5, each with a triangular apical tooth, tip green; the 2 lateral lobes 1.5–3.5 × 2–4 mm, with a short spike-like dorsal appendage 0.5–1 mm long, the 3 central lobes shorter, 1–2.5 × 1–2.5 mm, without an appendage; male free tepal exserted, oblong-lanceolate, 5.2–6.2 × 0.7–1.3 cm, orange-yellow, thickened, smooth, margins hyaline, apex rounded; stamens 5 nearly as long as the compound tepal but not exserted; filaments oblanceolate, 26–39 × 0.9–1.5 mm, yellowish; anthers lanceolate, 15–24 × 1–2 mm, yellow; pollen white; style straight, held and at the same level as the stamens, 43–59 × ca. 0.5, yellow, with no other pigmentation; stigma clavate, 5–8 × 3–5 mm, orange; ovary very short, 0.4–0.9 × 0.4–0.8 mm, yellow, with other no pigmentation, bearing some wax, glabrous. Fruiting peduncle to 35 cm, 4–5.5 cm in diam, green, glabrous. Fruit bunch cylindrical, compact, with 5 to 12 hands, 3 to 5(or 6) fruits per hand, arranged in a row, fingers orientated pendant to the stalk with age; mature fruits obloid, sometime obovoidobloid, 4–9 cm, 1.5–3.7 cm in diam., glaucous or silvery green, lacking of wax, straight, round in cross-section, apex blunt tipped or with a short point, bearing the persistent perianth, pulp white, with numerous seeds (ca. 20 to 45 per fruit); fruiting pedicels 2–3 × ca. 0.8 cm, glaucous green, glabrous; Seeds bell- or mushroom-shaped, 5.5–7 mm high, 6.5–9 mm in diam. at broadest part, brown, wrinkled, hilum 2–3 mm wide ( Figure 3 View FIGURE 3 ).

Habitat and ecology:—Secondary evergreen to open forest, often scattered on steep hills and in open areas in forest or near streams at ca. 530–700 m elevation.

Distribution:— Vietnam (Cao Bằng, Lai Châu, and Lào Cai provinces).

Vernacular names and uses:—Chuối gai, Chuối rừng hoa đỏ. Young pseudostems of Musa splendida are used as vegetables and as pig fodder. The cut inflorescence is used for decorative purposes by local people.

N otes:— Musa splendida resembles M. viridis Valmayor, Danh & Häkkinen (2004: 115) , but differs in having leaves whose lamina has a base that is rounded on both sides (vs. cuneate in M. viridis ) and bracts that are orange-red to bright red and imbricate (vs. pinkish-lilac and convolute).
