What is the habit of Urena lobata?
Urena lobata invades disturbed areas, pastures, eroded areas, and perennial crop plantations. Urena lobata tolerates salt spray but does not grow in saturated soils. Having an aggressive habit, this weed grows rapidly and can reach 2-7 ft. (0.6-2.1 m) by the end of the first year.

Urena/Scientific names
How is Urena dispersed?
Xanthium and urena seeds are adapted to be dispersed by the hooks and furs of animals.
How are Urena seeds dispersed?
This species reproduces by seed. The hooked spines on its fruit readily attach to animal fur and clothing. Seeds may also be dispersed by water, soil or contaminated agricultural produce.
How does Urena disperse its seeds?
Urena is a genus of plants which grow in various tropical and subtropical areas throughout the world. Some view the plant as a weed, but others make use of its fiber for various purposes. The leaves and flowers are also a famine food in Africa. Its seeds are spread by animals.
Which is the largest seed in the world?
Lodoicea maldivica, also known as the double coconut, or coco-de-mer, is renowned for producing the largest and heaviest seeds in the world.
How is the dandelion suited to its method of dispersal?
Some fruits—for example, the dandelion—have hairy, weightless structures that are suited to dispersal by wind. Seeds dispersed by water are contained in light and buoyant fruit, giving them the ability to float. Coconuts are well known for their ability to float on water to reach land where they can germinate.
How are Burr mallow seeds dispersed?
Means of Movement and Dispersal sinuata spreads by seeds. Fruits are covered with barbed-spines facilitating their dispersal attached to animal fur and people’s clothing. In addition, seeds may be dispersed in contaminated soil and/or contaminated agricultural equipment (Valkenburg and Bunyapraphatsara, 2001).
Which seeds are mainly dispersed by animals?
Examples include mangoes, guavas, breadfruit, carob, and several fig species. In South Africa, a desert melon (Cucumis humifructus) participates in a symbiotic relationship with aardvarks—the animals eat the fruit for its water content and bury their own dung, which contains the seeds, near their burrows.
Is urena dispersed by wind?
From the given figure it can be inferred that seeds of plants X are dispersed through explosion, e.g., Balsam and pea. Seeds of plant Y are dispersed by wind, e.g., Dandelion and Hiptage while seeds of plant Z are dispersed by animal, e.g., Xanthium, Urena.
