About Rubus pectinellus Maxim.
Rubus pectinellus Maxim., commonly known as atibulnak, is a small trailing woody shrub that typically grows 0.5 to 1 m (1.6 to 3.3 ft) in length. Its leaves are arranged alternately along stems, and are either heart-shaped or three-lobed. The leaves have a rough, hairy texture, serrated margins, and reach 3 to 6 cm (1.2 to 2.4 in) in diameter. Both leaves and stems are covered in small spines. This species produces white flowers that measure around 2 cm (0.79 in) in diameter. After flowering, it develops fruits that are 1.4 to 1.6 cm (0.55 to 0.63 in) in diameter, which turn bright red when fully ripe.
