Rubus fasciculatiformis

Rubus fasciculatiformis is a microspecies of bramble in the Rubus fruticosus aggregate, family Rosaceae, described from central Europe. Like other brambles it is a scrambling, perennial shrub producing long, arching biennial canes armed with prickles, which root at the tips to form dense thickets. The leaves are palmately compound, typically with three to five toothed leaflets that are green above and paler, often felted, beneath. The five-petalled flowers are white to pale pink and borne in branched clusters in summer. The fruit is an aggregate of small drupelets ripening from green through red to glossy black, the familiar blackberry. As an apomictic agamospecies it reproduces largely without sexual fertilisation, giving rise to stable, narrowly distributed forms. It occurs in hedgerows, woodland margins, scrub, and waste ground in temperate Europe.
