オオツメクサ
Spergula arvensis var. sativa,an
annual herb originating in Europe, lives wild in fields or
grasslands, growing to 30-50cm in height, with glandular hairs on
upper stems, peduncles, and leaves. The leaves are linear, 1.5-4cm
long; phyllotaxis is correctly opposite but appears in whorls, as
the axils produce too many brachyblasts with short internodes. Stem
tips are sparsely set with white flowers, featuring five sepals and
petals that are 3-4mm long. Bloom time: April-August.
