Rubus aboriginum is a North American species of dewberry, known as the garden dewberry and aboriginal dewberry. Like other dewberries, it is a species of flowering plant in the rose family, related to the blackberry. It is native to the United States and Mexico, primarily in the southern Great Plains.
Rubus aboriginum is a bushy, viny bramble, up to 6abbr=offNaNabbr=off in height and breadth, but often smaller. Branches appear 'hairy' when young, and become smooth as they mature, with infrequent, short, hooked thorns. The leaves are ovate, with serrated edges; flowers are white, have five petals, and are about 1abbr=offNaNabbr=off in diameter. The fruits resemble other dewberries or small blackberries.[1]
R. aboriginum is very closely related to the northern dewberry, Rubus flagellaris,[2] and is sometimes treated as a subspecies.[1]
It is native to the United States and Mexico, primarily in the southern Great Plains with additional populations scattered in the eastern US and in Nuevo León.
The species typically inhabits areas of rocky soil and partial shade, such as open woodlands and abandoned fields.
