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,
Fabiana (plant) The USDA’s listing indicates lack of commercial interest in the genus, rather than any scientific consensus of species number. While the Solanaceae family has been well studied and documented overall, this research attention has not been applied uniformly amongst the genera. Genera such as "Fabiana", with limited commercial or cultural agricultural value have been overlooked in detailed phylogenetic analysis. Fabiana (plant) Fabiana is a genus of flowering plants in the nightshade family, native to dry slopes in western South America. They are evergreen shrubs or subshrubs, with needle-like leaves and profuse tiny tubular flowers in summer. The common name is
