Rubus lasiococcus is a North American species of wild blackberry known by the common names roughfruit berry and dwarf bramble.
Description
Rubus lasiococcus is a tangling, prostrate shrub with very slender stolons spreading along the ground and rooting where their nodes come in contact with moist substrate, forming a mat. Some stems grow erect to bear flowers. The leaves are 2.5–6.5 centimetres (1–2+1⁄2 in) wide, each deeply divided into three lobes,[2] or compound into three toothed leaflets, borne on a petiole a few cm long. The inflorescence is a solitary flower or a pair of flowers with five reflexed sepals and five white petals each up to 1 cm (3⁄8 in) long.[2] The fruit is a densely hairy red aggregate about 1.3 cm (1⁄2 in) across.[3][2]
