Rubus chloocladus

Rubus chloocladus is a bramble or blackberry microspecies of the rose family (Rosaceae), described by the British batologist W.C.R. Watson and belonging to the apomictic Rubus fruticosus aggregate (subgenus Rubus) of central and western Europe. Like other members of this complex it is a scrambling, woody-stemmed shrub producing long arching biennial canes armed with prickles, which root at the tips. The leaves are palmately compound, usually with three to five toothed, green leaflets that are paler beneath. The five-petalled flowers are white to pale pink and borne in branched clusters, and are followed by aggregate fruits ripening from green through red to glossy black, the familiar blackberry. It grows in woodland margins, hedgerows, scrub and waste ground. The countless microspecies of this aggregate arise through hybridization and apomixis and are difficult to distinguish.
