VIN was intended as a vehicle to facilitate the exchange of information and seed stocks among individuals concerned with the breeding or testing of new varieties of vegetables. VIN regularly contained sections on research notes, variety announcements, stocks available, and stocks desired. It includes an interesting section on Ampelography which is a term used to describe the identification of grapevines based on morphology. An interesting project might be to develop a catalog of grape varieties based on leaf shapes. If your interest is in orchids, check out The Kew Gardens Orchid Research Newsletter .
