|discussion=<p><i>Rubus laciniatus</i> is the only blackberry in the flora area that has leaflets so deeply lobed and dissected or has 3-lobed petals. Rare individuals bearing relatively unlobed leaflets and perianth parts may be part of the natural variation of this species or be hybrids with some other species. Putative natural hybrids have been reported with <i>R. bifrons</i> (as R. procerus; R. K. Bammi and H. P. Olmo 1966). Such unusual plants of <i>R. laciniatus</i> would be distinguished from the native blackberries by their thyrsiform and notably stipitate-glandular inflorescences and evergreen to late-deciduous leaves.</p><!--
--><p>Although widely introduced in the flora area, <i>Rubus laciniatus</i> is a less aggressive weed than <i>R. bifrons</i>.</p>
