Costus dubius is a species of plant native to Tropical Africa. [1] [2]
Costus 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]
Costus 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:
In 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]

Asteraceae is a large family of flowering plants that consists of over 32,000 known species in over 1,900 genera within the order Asterales. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. The Asteraceae were first described in the year 1740 and given the original name Compositae. The family is commonly known as the aster, daisy, composite, or sunflower family.
The Zingiberales are flowering plants forming one of four orders in the commelinids clade of monocots, together with its sister order, Commelinales. The order includes 68 genera and 2,600 species. Zingiberales are a unique though morphologically diverse order that has been widely recognised as such over a long period of time. They are usually large herbaceous plants with rhizomatous root systems and lacking an aerial stem except when flowering. Flowers are usually large and showy, and the stamens are often modified (staminodes) to also form colourful petal-like structures that attract pollinators.
Amorphophallus is a large genus of some 200 tropical and subtropical tuberous herbaceous plants from the Arum family (Araceae), native to Asia, Africa, Australia and various oceanic islands. A few species are edible as "famine foods" after careful preparation to remove irritating chemicals. The genus includes the Titan arum of Indonesia, which has the largest inflorescence of any plant in the genus, and is also known as the 'corpse flower' for the pungent odour it produces during its flowering period, which can take up to seven years of growth before it occurs.
An inflorescence, in a flowering plant, is a group or cluster of flowers arranged on a stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (peduncle) and by the timing of its flowering.
Heliconia is a genus of flowering plants in the monotypic family Heliconiaceae. Most of the 194 known species are native to the tropical Americas, but a few are indigenous to certain islands of the western Pacific and Maluku in Indonesia. Many species of Heliconia are found in the tropical forests of these regions. Most species are listed as either vulnerable or data deficient by the IUCN Red List of threatened species. Several species are widely cultivated as ornamentals, and a few are naturalized in Florida, Gambia, and Thailand.
Chlorophytum comosum, usually called spider plant or common spider plant due to its spider-like look, also known as spider ivy, airplane plant, ribbon plant, and hen and chickens, is a species of evergreen perennial flowering plant of the family Asparagaceae. It is native to tropical and Southern Africa but has become naturalized in other parts of the world, including Western Australia and Bangladesh. Chlorophytum comosum is easy to grow as a houseplant because of its resilience, but it can be sensitive to the fluoride in tap water, which commonly gives it "burnt tips". Variegated forms are the most popular.
Costaceae, known as the Costus family or spiral gingers, is a family of pantropical monocots. It belongs to the order Zingiberales, which contains horticulturally and economically important plants such as the banana (Musaceae), bird-of-paradise (Strelitziaceae), and edible ginger (Zingiberaceae). The seven genera in Costaceae together contain about 143 known species. They are native to tropical climates of Asia, Africa, Central America, and South America. Several species are frequently found in cultivation.
Costus is a genus of herbaceous perennial plants in the family Costaceae, erected by Linnaeus in 1753. It is widespread through tropical and subtropical regions of Asia, Africa, and the Americas.
Cheilocostus speciosus, or crêpe ginger, is a species of flowering plant in the family Costaceae. Some botanists have now revived the synonym Hellenia speciosa for this species.
Emilia sonchifolia, also known as lilac tasselflower or cupid's shaving brush, is a tropical flowering species of tasselflower in the sunflower family. It is widespread in tropical regions around the world, apparently native to Asia and naturalized in Africa, Australia, the Americas, and various oceanic islands.
Lipocarpha is a genus of sedges known as halfchaff sedges. There are approximately 35 species and representatives can be found throughout the tropical and warmer temperate areas of Africa, Asia, Australia, North America, South America and various oceanic islands. These mostly are erect annual herbs growing 1 to 30 centimeters tall. The inflorescence consists of one to few spikes each containing many spirally arranged spikelets. The flower is entangled with two hyalin scales, a spikelet prophyll and a glume. These flower stands in the axil of a spikelet-bract.
Costus osae is a species of flowering plant in the family Costaceae. One of many rare tropical plants in the Costus family, Costus osae is a species native to Costa Rica described in 1997 . It has also been reported from Colombia.
Musa ornata, the flowering banana, is one of more than 50 species of banana in the genus Musa of the family Musaceae. Most of these species are large tropical evergreen perennials, mainly from lowland areas with high temperature and humidity. Musa ornata originated in southeast Asia, and is cultivated for its commercial and ornamental value. The fruit is attractive but tends to be inedible.
Costus spicatus, also known as spiked spiralflag ginger or Indian head ginger, is a species of herbaceous plant in the Costaceae family.
Senna italica, the Port Royal senna, Italian senna, or Senegal senna is a legume tree in the genus Senna. It is recognized by many other common names based on the regions it grows in. In India, it is used to produce a powder for treating hair-related diseases which is known as “neutral henna”. Whereas, in some parts of the world, this species is cultivated for the leaves which yield the drug senna, known commonly as Senna glycoside, which in turn is the base for a laxative. Senegal senna is easily distinguishable through its many distinctive features. There are 3 subspecies of this plant based on the size of the inflorescence and the length of the petiole. The subspecies are italica, micrantha, and arachoides. In many regions, this plant is cultivated commercially and medicinally.
Hellenia is a genus of plants in the Costaceae described as a genus with this name in 1791. It is native to Southeast Asia, southern China, the Indian Subcontinent, New Guinea, and Queensland. The type species was "H. grandiflora" Retz., which is a synonym of Hellenia speciosa.
Costus spectabilis, commonly known as the yellow trumpet, is an African, gregarious species of herb; low and perennial, it is found from Sierra Leone to Sudan to as far south as Angola and Zimbabwe.
Costus curvibracteatus is a tropical rhizomatous perennial native to Costa Rica and Panama. A member of the spiral ginger family of plants, its common name is orange tulip ginger. It is also sometimes referred to as spiral ginger; however, this common name is better associated with Costus barbatus, a more widely cultivated and very similar species. Despite the name and its relation to the ginger family (Zingiberaceae), the rhizomes of the orange tulip ginger are not edible.
Costus woodsonii, the red button ginger or scarlet spiral flag, is a species of flowering plant in the family Costaceae, native to Nicaragua, Costa Rica, Panama, and Colombia. A rhizomatous geophytic perennial, it is recommended for coastal gardens, borders, containers, and general wet, tropical garden applications.
Costus pulverulentus, the red cigar or spiral ginger, is a species of flowering plant in the family Costaceae. It is native to Mexico, Central America, Colombia, Venezuela, and Ecuador, and it has been introduced to Cuba. A rhizomatous perennial reaching 4 to 6 ft, it is typically found in wet tropical areas. It is used as an ornamental, and there are cultivars, including 'Serena', 'Pink Lips', and 'Purple Passion'.
