Previous knowledge: Basic knowledge of creating one’s own herbarium and knowledge of the identification of species.
Duration: approx.45 min
Materials / Conditions: Internet
Methods / Techniques: Individual work, description, identification
Learning subject: Biodiversity / Module 3: Collection, processing and analysis of environmental data / Level: advanced learning


Introduction:
According to their individual characteristics, plants are divided into classes, subclasses, orders, families, subfamilies, genera and species. In most cases, this systematics comes with fixed suffixes:
Class: -opsida (Magnoliopsida)
Subclass: -idae (Rosidae)
Order: -ales (Rosales)
Family: -aceae (Rosaceae)
Subfamily: -oidae (Maloidae)
There are no suffixes determined for genera and species.

2. Take notes of all of your plant’s features e.g. hair on the petals, number and color of petals etc.

3. Identify the plant’s family on the basis of the features you identified and create a label featuring the following information: family, location, gatherer, date.
