Lianas are a common woody vine found in tropical forests. These vines utilize trees to venture into the canopy in search of sunlight and nutrients. Thus, when a tree falls, it brings all the liana growth with it. Following a tree fall, lianas have a high survival rate (~90%) and they can quickly begin sprouting. [5]
Lianas can form bridges amidst the forest canopy, providing arboreal animals, including ants and many other invertebrates, lizards, rodents, sloths, monkeys, and lemurs with paths across the forest. For example, in the Eastern tropical forests of Madagascar, many lemurs achieve higher mobility from the web of lianas draped amongst the vertical ...
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.
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]
Maclura cochinchinensis, commonly known as cockspur thorn, is a species of vine or scrambling shrub in the family Moraceae. The native range extends from China, through Malesia and into Queensland and northern New South Wales. [1] The species inhabits various types of tropical forest: most commonly in monsoon forests. [2]
Tecomanthe speciosa (also known as the Three Kings vine or akapukaea) is a species of subtropical forest lianes. A single specimen was first discovered on Manawatāwhi / Three Kings Islands , 55 km (34 mi) off the northern tip of New Zealand , during a scientific survey in 1945. [ 2 ]
The pinnules are somewhat leathery, asymmetrical or oblique, and measure up to 10 cm (3.9 in) long by 5 cm (2.0 in) wide. [5] [6] [7] The inflorescences take the form of a spike measuring around 25–30 cm (9.8–11.8 in) long, carrying numerous sessile flowers. The individual flowers are very small, measuring only about 1.2 mm (0.05 in) diameter.
Thunbergia laurifolia is a popular ornamental plant in tropical gardens. It is a long-blooming vine in cultivation. Propagation is from stem cuttings or shoots from the tuberous roots. It is a fast-growing perennial herbaceous climber. It has become an exotic weed in many tropical countries.
