Dimorphanthes

Dimorphanthes is a genus of flowering plants in the family Gesneriaceae, native to the tropical regions of South America. The genus is characterized by its distinctive inflorescence, which consists of a terminal raceme of flowers, each with a unique structure. The flowers are typically small, with a corolla that is bilabiate, meaning it has two lips. The upper lip is often larger and more prominent, while the lower lip is typically three-lobed. The genus is named for its dimorphic flowers, which can vary in size and shape within the same inflorescence.

Dimorphanthes species are often epiphytic, meaning they grow on other plants rather than in the soil. They are commonly found in the understory of tropical rainforests, where they can be an important source of food for local wildlife. The genus is of particular interest to botanists and horticulturists due to its unique floral morphology and the challenges it presents for classification and identification.

The genus includes several species, the most well-known of which is Dimorphanthes sanderi. This species is notable for its striking flowers, which can be bright red, orange, or yellow, and its ability to thrive in a variety of conditions, including as an epiphyte or in hanging baskets. Other species in the genus include Dimorphanthes aurea and Dimorphanthes rubra, both of which are similarly characterized by their dimorphic flowers and epiphytic habits.

Dimorphanthes plants are valued for their ornamental qualities and are often cultivated in gardens and greenhouses. They require bright, indirect light and well-draining soil to thrive. With proper care, they can produce beautiful, long-lasting flowers that add a touch of tropical elegance to any setting.
