Vinca rosea, commonly known as Madagascar periwinkle, exhibits a simple, opposite leaf arrangement with a reticulate or net-like venation pattern. The primary veins run parallel to each other and branch out into smaller veins that create a network throughout the leaf. This venation helps in supporting the leaf structure and facilitating efficient nutrient transport.
Vinca minor and Vinca rosea (often referred to as Catharanthus roseus) are both part of the Apocynaceae family, making them close relatives. However, they belong to different genera; Vinca minor is classified under the genus Vinca, while Vinca rosea is under the genus Catharanthus. Despite their familial connection, they have different characteristics and uses in horticulture and medicine.
Leaf venation refers to the pattern of veins in a leaf. There are two main types of leaf venation: parallel venation, where the veins run alongside each other in a parallel pattern, and reticulate venation, where the veins branch and form a network-like pattern across the leaf. The type of venation can be used as a characteristic for identifying plant species.
Cassia leaf has reticulate venation. This type of venation is generally found in dicot leaves.
Alternate phyllotaxy
Dicotyledonous leaf have reticulate venation and monocotyledonous leaf have parallel venation.

No. Vinca Minor, also known as Lesser Periwinkle, originates in Europe, whereas Vinca Rosea (correctly named Catharanthus roseus), also known as Madagascar Periwinkle is endemic to Madagascar.
