Galium kamtschaticum var. acutifolium is a perennial herb in conifer forests in the subalpine zone; rhizomes are thin, scrawling underground shallowly, branching, and making fibrous roots at nodes. Stems are square and erect, 20-40cm in size. Leaves are in four whorls, in the shape of an oblong or long-oblong, 2-5cm long, with tips pointed and bristles on both surfaces and margins. Stem tips or axils on upper parts emerge cymes and sparsely set small yellow-green flowers. Bloom time: June-July.
