Context paragraphs:
Terminalia ferdinandiana: Terminalia ferdinandiana, also called the gubinge, billygoat plum, Kakadu plum, green plum, salty plum, murunga or mador, is a flowering plant in the family Combretaceae, native to Australia, widespread throughout the tropical woodlands from northwestern Australia to eastern Arnhem Land.  It has a high concentration of vitamin C in its fruit: recorded concentrations of 2300–3150 mg/100 g wet weight and occasionally as high as 5300 mg/100 g, compared with 50 mg/100 g for oranges, ranks among the highest known of any natural source.

Oeceoclades ugandae: Oeceoclades ugandae is a terrestrial orchid species in the genus "Oeceoclades" that is native to parts of tropical Africa, including west tropical Africa (Ghana and Ivory Coast), west-central tropical Africa (Gulf of Guinea islands and the Democratic Republic of the Congo), northeast tropical Africa (Ethiopia), and east tropical Africa (Kenya and Uganda).  It was first described by the British botanist Robert Allen Rolfe in 1913 as "Eulophia ugandae" and later transferred to the genus "Oeceoclades" in 1976 when Leslie Andrew Garay and Peter Taylor resurrected and revised that genus.  The English botanist V.S. Summerhayes treated this species as a synonym of "O. latifolia", but Garay and Taylor noted that while the two species share a superficial resemblance in the appearance of the labellum, they are distinct in vegetative morphology.  The labellum of "O. ugandae" also has two swellings or protuberances between the lateral and midlobes, a feature that "O. latifolia" lacks.

Pavetta: Pavetta is a genus of flowering plants in the Rubiaceae family.  It comprises about 350 species of trees, evergreen shrubs and sub-shrubs.  It is found in woodlands, grasslands and thickets in sub-tropical and tropical Africa and Asia.  The plants are cultivated for their simple but variable leaves, usually opposite but also occur in triple whorls.  The leaves are often membranous with dark bacterial nodules.  "Pavetta" has small, white, tubular flowers, sometimes salviform or funnel-shaped with 4 spreading petal lobes.  The flowers are carried on terminal corymbs or cymes.

Deschampsia antarctica: Deschampsia antarctica (Antarctic hair grass) is one of two flowering plants native to Antarctica, the other being "Colobanthus quitensis" (Antarctic pearlwort).

Ochna: Ochna is a genus comprising 86 species of evergreen trees, shrubs and shrublets belonging to the family "Ochnaceae".  These species are native to tropical woodlands of Africa, the Mascarenes and Asia.  Species of this genus are usually called Ochnas, Bird's-eye bushes or Mickey-mouse plants, a name derived from the shape of the drupelet fruit.  The name of this genus comes from the Greek word "Ochne", used by Homer and meaning "wild pear", as the leaves are similar in appearance.  Some species, especially "Ochna serrulata" (bird's eye plant), are widely cultivated as decorative plants.

Commiphora: The genus of the myrrhs, Commiphora, is the most species-rich genus of flowering plants in the frankincense and myrrh family, Burseraceae.  The genus contains approximately 190 species of shrubs and trees, which are distributed throughout the (sub-) tropical regions of Africa, the western Indian Ocean islands, the Arabian Peninsula, India, and Vietnam.  The genus is drought-tolerant and common throughout the xerophytic scrub, seasonally dry tropical forests, and woodlands of these regions.

Mucuna: Mucuna is a genus of around 100 accepted species of climbing lianas (vines) and shrubs of the family Fabaceae and typically found in tropical woodlands.

Jaborosa: Jaborosa is a genus of flowering plants in the family Solanaceae, the nightshades.  There are about 23 species, all native to South America, where they are distributed from Peru to Patagonia.  Most occur in the Andes.  Most can be found in Argentina and ten are endemic to the country.

Dichorisandra thyrsiflora: Dichorisandra thyrsiflora or blue ginger is a tropical plant which resembles ginger in growth and habit, but is actually related to the spiderworts (the genus "Tradescantia").  The plant is native to the tropical woodlands of North, Central and South America, specially in Atlantic Forest vegetation in Brazil.  Of the family Commelinaceae, they are cultivated for their handsome spotted stems, large shiny foliage which is held horizontally, surmounted by striking blue flowers.

Oeceoclades saundersiana: Oeceoclades saundersiana is a terrestrial orchid species in the genus "Oeceoclades" that is native to a large area in tropical Africa.  It can be found in west tropical Africa (Benin, Ghana, Guinea, Ivory Coast, Liberia, Nigeria, and Sierra Leone), west-central tropical Africa (Central African Republic, Cameroon, Equatorial Guinea, Gabon, the Gulf of Guinea islands, Rwanda, and Democratic Republic of the Congo), northeast tropical Africa (Ethiopia), east tropical Africa (Kenya, Tanzania, and Uganda), and south tropical Africa (Angola and Zambia).  It was first described by the German botanist Heinrich Gustav Reichenbach in 1866 as "Eulophia saundersiana".  It was later transferred to the genus "Oeceoclades" in 1976 by Leslie Andrew Garay and Peter Taylor.  Garay and Taylor noted that "O. saundersiana" has a labellum with four lobes of equal size and the pseudobulb is long and cylindrical with two leaves.
