. In addition to ''R. cissoides,'' there are four other endemic species of ''Rubus'' in New Zealand, including '' R. australis, R. parvus, R. schmideloides,'' and '' R. squarrosus.'' These can be distinguished from one another using prickle, leaf, inflorescence and fruit characteristics. ''Rubus cissoides'' is the most common native species in New Zealand, and has sharply toothed leaflets that are long and narrow. Plants of this species can grow very high - over 15 metres above the ground - and stems may be 17 cm in diameter. Many of the native New Zealand ''Rubus'' species, including ''R. cissoides,'' are commonly called bush lawyer or tātarāmoa in te reo Māori, and other vernacular names for this and other similar ''Rubus'' species in New Zealand include taramoa, akatātarāmoa, taraheke, and tātaraheke. They are considered to be "hook climbers", and are woody, low to high climbing vines or lianes that have backwardly curving hooked prickles, which allow the plant to grip, climb up and find support on shrubs or other vegetation.
