Plant morphology share the same basic structure and development as leaves in other plants, and therefore cactus spines are homologous to leaves as well. This aspect of plant morphology overlaps with the study of plant evolution and paleobotany. Secondly, plant morphology observes both the vegetative (somatic) structures of plants, as well as the reproductive structures. The vegetative structures of vascular plants includes the study of the shoot system, composed of stems and leaves, as well as the root system. The reproductive structures are more varied, and are usually specific to a particular group of plants, such as flowers and seeds, fern sori,
Bush lawyer (plant) name of "Rubus cissoides", but North Americans certainly do. In New Zealand the thorny vine is best known as bush lawyer. Found throughout the country up to 1000m, the plant has hand-shaped leaves with three to five toothed 'fingers', white flowers and a yellowish-red fruit. The berry is shaped like a small blackberry and was once used by early Europeans to make jams and jellies. But the plant's most noticeable feature is its thorns. The backward-pointing prickles on the stems help the vine climb to the open canopy of a forest but also snare unwary trampers who stray from the
