|Galium odorata is a
perennial herb borne in forests in mountainous regions, stems
growing to 20-30cm in height without branching, with whorls of six
to ten leaves around them. The leaves, with no petioles, are narrow,
long-oblong, or oblanceolate, 1.5-4cm in length, 3-13mm in width.
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 and
set 4-12 white flowers in them. Corollas are funnel-shaped with tips
cleft in four, and stamens are four in number. Bloom time: May-July.
