A new online guide removes the guesswork when it comes to identifying flora. The Royal Botanical Gardens Victoria have published the world's first online "horticultural flora" a compendium of information on the 8700 different types of plants being cultivated in south-eastern Australia. The guide provides plant profiles and identification tools for many of the cultivars of every plant - native and exotic - growing in Victoria, South Australia, Tasmania, NSW and south-eastern QLD. It includes descriptions of the plants, their origin and general history, and contains illustrations that highlight a plants identifying features. There are also botanical keys to follow a sequence of identification steps and the names of parks and gardens where you can see them growing. Encyclopedic in approach , the online flora digitises the information in the five-volume, 2700 page Horticultural flora of Southeastern Australia.
