Galium odorata / Kurumabasou クルマバソウ

Galium odorata is a perennial herb found in forests of mountainous regions, with stems growing to 20-30cm in height, unbranched, and surrounded by whorls of six to ten leaves. The leaves, with no petioles, are narrow, long-oblong, or oblanceolate, 1.5-4cm long and 3-13mm wide. Correctly, the phyllotaxis of this species is opposite; 2 out of 6-10 are real opposite leaves, and the other 4-8 are stipules - seemingly no differences in shape and size. Stem tips bear cymes, each set with 4-12 white flowers. Corollas are funnel-shaped with tips cleft into four parts, and stamens are also four in number. Bloom time: May-July.
