Rubus squarrosus, leafless lawyer or yellow-prickled lawyer is endemic to the North and South Islands, from Ahipara south (rare north of the Manawatu). It is found in lowland forest and in usually open rocky places. A vigorous and sparsely foliaged climber, in forest situations, can climb up to 10m high, but in the open becomes a scrambling shrub up 1.5m high found, with white flowers in spring.  Plant in either a dry or moist soil in full sun. Frost hardy and can cope with an exposed aspect. The prickles, which are mostly on the petioles and midribs, are bright creamy yellow, and against the dark green stems give this plant a distinctive appearance. Excellent as a security plant, and certainly would make a great hedgerow, as it is effectively natures barbed-wire. Not threatened but often local and uncommon over large parts of its potential range. Some northern populations are very vulnerable to habitat destruction.
