Description
editCostus dubius has underground rhizomes which produce leafy stems and inflorescences on separate stalks.[3] The round inflorescences have green bracts; each bract produces a single white flower with a yellow-centered labellum. Costus dubius produces many seeds.[2]
Costus dubius is sometimes confused with several other African species of Costus, such as Costus afer and Costus dinklagei.[4][2] Costus dubius is the only African species of Costus capable of self-pollination.[2]
Range
editCostus dubius has a wide native range and can be found throughout tropical Africa.[2]
Costus dubius has been introduced to several places in which it has become naturalized or invasive including:
- Queensland, Australia[1]
- Java, Indonesia[5]
Habitat
editIn its native Africa, Costus dubius is found in many different types of forest, as well as along rivers and roads and in plantations.[2] Costus dubius prefers wet tropical biomes and does not appear to survive in the subtropics.[4][1]
