The Landmark Trees were organised, like all living things, onto the Tree of Life- a conceptual branching tree used to organise all biological species. The work to conduct this classification is the discipline of taxonomy.
Approximately 210 species of tree were identified in the 962 Landmark Trees. Some were familiar and famous, such as the much-loved neem tree, and some were obscure and only a single death away from utter extinction in the wild, such as the Elaeocarpus blascoi.
The species binomial is a two-part name which identifies the species. Species binomials are almost always derived from Latin or Greek words. Each species is encompassed within a single genus. The genus is the first of the two words. The genus is itself encompassed with a single family.
When you encounter a species binomial on this site, you can click on it to learn about it on an external database, such as Wikispecies, or to see other trees in the database of the same species.
You can also explore the different species by following the listings in the Botany sidebar.
What is a species? You can find the following definition at Wikipedia:
In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring.
Species that are believed to have the same ancestors are grouped together, and this group is called a genus. A usable definition of the word “species” and reliable methods of identifying particular species are essential for stating and testing biological theories and for measuring biodiversity, though other taxonomic levels such as families may be considered in broad-scale studies. The total number of non-bacterial species in the world has been estimated at 8.7 million, with previous estimates ranging from two million to 100 million.
Common names, by contrast, may be in any language and are often imprecise. In this study, the species binomial is linked to a Common Name. You may notice that the Common Names are often presented in multiple. For example, on of the the largest species of tree in the world is alternately known as Banyan, Vad, Bad, or Baragad in north India, but has different common names in different places and in different languages.
As a reference for identification and names, we primarily followed Pradip Krishen’s Trees of Delhi. This is by far the best tree guide available for trees of India (excluding mountain regions), and we strongly suggest you purchase a copy (by clicking here, via Amazon.com). When we were in forests where we could not use this book , we followed the identifications and names of the experts we met along the way. Sometimes, in botanical gardens, the trees were conveniently labelled.
Too often, we were unable to come up with a positive identification of a tree that we met. When this happened, this is marked clearly. If you know the species of any of the unidentified trees in the is project, or if you find any corrections that need to be made, please send us an email following the correction links at the bottom of each tree profile.
A handful of the Landmark Trees have two, or even three, species associated with them, when several organisms grow together in one mass. These multiple trees are marked with the Fusion attribute tag.
