ous plant
that belongs to the genus
Stylidium (family Stylidiaceae
). The specific epithet is from the Latin accedens, which means "resembling", referring to the resemblance of this species to another Stylidium species, S. uliginosum

. The leaves are generally 5-12 mm long and 2.5-5.5 mm wide. This species generally has one to two scapes
and cymose inflorescence
s that are 4-15 cm long. Flowers are white. S. accedens is found around and northeast of Katherine
in the Northern Territory
of Australia
. Its typical habitat is a shallow, sandy soil on a sandstone plateau. It flowers in the southern hemisphere
from June to July. S. accedens is most closely related to S. simulans
. Its conservation status
