Botanists define vascular plants by three primary characteristics: Vascular plants have vascular tissues which distribute resources through the plant. Two kinds of vascular tissue occur in plants: xylem and phloem. Phloem and xylem are closely associated with one another and are typically located immediately adjacent to each other in the plant.
Plant morphology. Phytomorphology is the study of the physical form and external structure of plants. [ 1] This is usually considered distinct from plant anatomy, [ 1] which is the study of the internal structure of plants, especially at the microscopic level. [ 2] Plant morphology is useful in the visual identification of plants.
Curculigo is a flowering plant genus in the family Hypoxidaceae, first described in 1788. It is widespread across tropical regions of Asia, Africa, Australia, and the Americas. [2] [3] Curculin is a sweet protein that was discovered and isolated in 1990 from the fruit of Curculigo latifolia, [4] a plant from Malaysia.
