Gesneriaceae is a family of flowering plants comprising more than 150 genera and 3200 species found in tropical and subtropical areas although there are some temperate representatives from Asia and Europe. Most are perennial herbs, but there are also some shrubs, small trees, annuals, epiphytes and climbers. They can also be divided by how their stems are modified into storage organs. Some are rhizomatous, others tuberous, and others described as having fibrous roots (but no storage structures.) Leaves are usually opposite, herbaceous or leathery. Many of the flowers are very showy and colorful with a 5 lobed corolla with fused petals. The fruit is a capsule with many small seeds.
Species with wiki pages are Achimenes and Sinningia
