Impatiens yinyinkyii M.M.Latt, B.B.Park & Nob.Tanaka and I. horizontalis M.M.Latt, B.B.Park & Nob.Tanaka (Balsaminaceae) are described and illustrated. Those new species were discovered in Htamanthi Wildlife Sanctuary, northwestern Myanmar. Description, photographic data as well as the comparative characters with their similar species are provided. Impatiens yinyinkyii is similar to I. masonii Hook.f., but differs in having three dark purple blotches in center of flower, specifically at base of dorsal and upper petals of united petals. Impatiens horizontalis resembles I. stenantha Hook.f., I. prostrata Hook. f., I. repens Moon, I. procumbens Franch and I. reptans Hook. f. in having larger, glabrous and elliptic to lanceolate leaves, serrate margin with antrorse bristles, deeply bucciniform lower sepal, twisted spur with abruptly capitate tip, linear ovary, spheroid seed and finally uncommon conspicuous stout stem which is horizontally creeping.
