The Plant List

The description and classification of plant species is still an ongoing process and I don't think we will get a full list of all plant species for many years. At the moment, the number of species is estimated at around 450000. The World Flora Online aims to gather all current knowledge on the classification of plant species worldwide by gathering information from national Floras and regional accounts. This project was initiated to answer Target 1 of the Global Strategy for Plant Conservation , a part of the Convention on Biological Diversity, which was to "understand, document and recognize plant diversity" and to create a World Flora by 2020. The task is so enormous that the target has not been met, but great efforts have been made by research institutions around the world to work towards it. If you want a list of all the names of plants that have ever been published, you can look at the International Plant Names Index . You will find the plant name, the author who described it and the reference to the original publication. This list does not take into account the current validity of the names (whether the names are still used or now considered synonyms of something else). The Plantlist used to be a reference to check if the names are valid or not (according to the most recent literature), but it is not updated anymore. Kew's Plants of the World Online is a good resource too but it is not an exhaustive list either. Edit: If you are interested in the evolution and phylogeny of flowering plants, the Angiosperm Phylogeny Website is a goldmine. It is quite technical, but you will find interesting explanations about the concepts of classification, systematics, phylogeny etc. on the home page. More on reddit.com

I know Peashooter and Sunflower are bad but they have a special place in my heart. Kinda like 2fort. More on reddit.com
