4A6887D2FFDEFFE78707F41DFAE9F8F2.taxon	description	Impatiens marroninus is similar in morphology to I. beccarii Hook. f. ex Dunn. In I. marroninus the leaf is dark green; lower sepal deeply navicular, constricted into a shortly curved spur; lateral petals symmetrical, yellow with red maroon stripes in the upper part (latter unique to Impatiens). Impatiens beccarii (Fig. 1 c – d) has green leaves; lower sepal shallowly navicular and constricted into a curved filiform spur; lateral petals ± asymmetrical, yellow with red or orange markings. Both species are endemic to Sumatra. — Type: H. Wiriadinata 14280 (holo BO), Indonesia, South Sumatra, Muara Enim, Palembang. Glabrous perennial herbs, up to 80 cm tall; stems erect, simple. Leaves spirally arranged, somewhat congested towards the stem tops, dark green; petiole 1 ‒ 3 cm long; lamina ovate to elliptic, 5 ‒ 15 by 2.5 ‒ 5 cm, base acute, margin crenate, apex obtuse to acuminate, lateral veins 5 ‒ 8 pairs. Inflorescences 1 – 2 - flowered racemes; peduncles c. 3.5 cm long, maroon; bracts linear, 1 ‒ 3 cm long. Flowers yellow. Sepals: lateral two ovate, c. 1 by 1 cm, white to maroon; lower sepal deeply navicular, c. 1.5 by 1 cm, constricted into a short curved spur, latter reddish, c. 1.5 cm long. Petals: upper lateral petals usually with maroon stripes in upper part; dorsal petal cucullate, c. 2 by 0.5 cm, yellow with red stripes outside; lower lateral petals united, c. 3 by 1 cm; upper part of each pair oblong to suborbicular, c. 1.5 by 1 cm, yellow with smooth red stripes; lower part of each pair ovate to subovate, c. 1.5 by 1 cm, yellow with red stripes. Ovary glabrous. Fruit unknown.	en	Utami, N. (2020): Impatiens marroninus, a new species of Impatiens (Balsaminaceae) from Sumatra, Indonesia.
