This module is composed of two parts: Floristics and Herbarium techniques. The first part, Floristics, is a study of the distribution, number, types and relationships of plant species in an area or areas. It is a sub-domain of Botany and Biogeography. It is the science of identifying the diversity of plants across a given geographic region. The second part, a herbarium, is a reference collection consisting of carefully selected and dried plants attached to paper sheets of standard size and filed in a systematic way. Herbaria are also the fundamental source of information for the identification and classification of plants and represents the backbone of taxonomic knowledge and thus of all disciplines in need of communicating about plants.
