Ch 12Taxonomy of Angiosperms — Class 11 Botany, concept-first.
Whenever a botanist encounters a plant, three separate but related tasks are involved in making sense of it: figuring out what it is by comparing it with known plants (identification), giving it a scientifically valid name that everyone can use without confusion (nomenclature), and placing it in an appropriate group al…

Systems of Classification
Plant classification systems have changed considerably as botanical knowledge has grown, and it helps to see the range of approaches side by side.
Semi-Technical Description of a Typical Flowering Plant
When a taxonomist writes up a description of a flowering plant for identification or comparison, the description is not composed freely; it follows a fixed order of characters every time, so that desc…
Family Fabaceae
Family Fabaceae, traditionally also called Papilionaceae because of its butterfly-shaped corolla, is placed in the subclass Polypetalae of Bentham and Hooker's classification, since its petals remain…
Family Solanaceae
Family Solanaceae is placed under the subclass Gamopetalae in Bentham and Hooker's classification, since its petals are united into a single fused corolla, unlike the free-petalled condition of Fabace…
Family Liliaceae
22 QFamily Liliaceae belongs to the class Monocotyledonae, and within that class it is placed under the series Coronariae in Bentham and Hooker's scheme.
