This vine will grow in all seasons and typically spreads along forest floors. The vine grows in two ways: through rhizomes, or through new shoots that grow where the stem has been cut. [ 11 ] As Gnetum africanum is a wild forest vine, it tends to grow best in shaded areas. [ 9 ]
A liana is a long-stemmed woody vine that is rooted in the soil at ground level and uses trees, as well as other means of vertical support, to climb up to the canopy in search of direct sunlight. [1] The word liana does not refer to a taxonomic grouping, but rather a habit of plant growth – much like tree or shrub .
There are some tropical vines that develop skototropism, and grow away from the light, a type of negative phototropism. Growth away from light allows the vine to reach a tree trunk, which it can then climb to brighter regions. [6] The vine growth form may also enable plants to colonize large areas quickly, even without climbing high.
[1] Rainforests and vine thickets have a present extent of 36,469 km 2, of which 22,694 km 2 is in protected areas. [1] Rainforests and vine thickets are present in 36 of Australia's bioregions. The largest extent of rainforest in Australia is in the Queensland tropical rain forests ecoregion (Wet Tropics bioregion).

Apocynaceae (/ ə ˌ p ɑː s ə ˈ n eɪ s i ˌ aɪ,-s iː ˌ iː /, from Apocynum, Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, [1] because some taxa were used as dog poison.
Amazon River rain forest in Peru. Tropical rainforests are hot and wet. Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year. [4] Average annual rainfall is no less than 1,680 mm (66 in) and can exceed 10 m (390 in) although it typically lies between 1,750 mm (69 in) and 3,000 mm (120 in). [5]
