gesnerioides

Gesnerioides is a genus of flowering plants in the family Gesneriaceae, native to the tropical Americas. The genus includes several species of herbaceous perennials that are often epiphytic or lithophytic, growing on tree trunks or rocky substrates in humid forests. Plants typically have opposite leaves, with slender stems and rhizomatous or creeping growth. Flowers are tubular and bilabiate, arranged in terminal or axillary inflorescences; tube colors range from red, orange, yellow to pink, often with a contrasting throat and extended nectar guides. Pollination is commonly by hummingbirds and bees. The fruit is a dry capsule containing numerous seeds.

Distribution and habitat: Gesnerioides species are native to Central and South American humid forests, including cloud forests, at elevations from lowlands up to montane zones. They prefer warm, humid conditions with bright, indirect light.

Taxonomy and naming: Gesnerioides has been treated as a distinct genus within Gesneriaceae, with the name meaning “resembling Gesneria.” Taxonomic circumscription has varied in the face of new molecular data, but it is generally regarded as a valid genus comprising neotropical species related to other members of the family.

Cultivation: In cultivation they are grown primarily by collectors and greenhouse enthusiasts. They require well-draining, porous potting mixes, high humidity, and good air circulation. Watering should be regular but not excessive, allowing the substrate to dry slightly between waterings. They often benefit from temperature ranges that include cool nights.

Conservation: Many species have restricted ranges and are threatened by habitat loss in tropical forests.
