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,
Dolichos (plant) Dolichos (plant) Dolichos is a genus of flowering plants in the legume family, Fabaceae, and the subfamily Faboideae. It is distributed in Africa and Asia. The lablab bean ("Lablab purpureus") was formerly included in "Dolichos". These are herbs and shrubs growing upright, sometimes with climbing stems, or spreading prostrate upon the ground. They have woody rhizomes. The leaves have single blades or are pinnate, divided into three leaflets. The plants sometimes produce their leaves after flowering. The flowers are solitary or in racemes of several. The flowers are white or purple, or occasionally yellow. The fruit is a flattened legume
