The fruit resembles a tumbleweed in that it is wind-dispersed and tumbles, an unusual mechanism of seed dispersal (see Diaspore (botany)). Anemone virginiana was also given the common name "Thimbleweed" due to its pistil resembling the shape of a thimble. This plant is very durable in different weather conditions, ranging from part shade to sun ...
The second major step in the development of pecan was a change from wind-dispersed fruits to animal dispersion. This dispersal strategy coincides with developing a husk around the fruit and a drastic change in the relative concentrations of fatty acids. The ratio of oleic to linoleic acids is inverted between wind- and animal-dispersed seeds.
The fruit is a multicapsular spherical head and hangs on the branches during the winter. The woody capsules are mostly filled with abortive seeds resembling sawdust. [13] The seeds are about 6 mm (1 ⁄ 4 in) thick, winged, and wind-dispersed.
Epilobium hirsutum seed head dispersing seeds. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds.
In late summer or autumn the fruit appear; they are siliques about 20–50 centimetres (8–20 in) long, full of small flat seeds, each with two thin wings to aid in wind dispersal. The large leaves and dense foliage of Catalpa species provide good shelter from rain and wind, making the trees an attractive habitat for many species of birds ...
The pappus-clad fruits that make up the familiar "dandelion clock" being dispersed by the wind (family Asteraceae) Bidens frondosa achenes with barbed pappusIn Asteraceae, the pappus is the modified calyx, [1] the part of an individual floret, that surrounds the base of the corolla tube in flower.
Fruit-eating birds typically swallow small seeds but, like bats, may carry larger seeded fruits to a perch where they eat the fruit and discard the seed. Diaspores such as achenes and samarae are dispersed primarily by wind; samaras are dispersed also by sailing or tumbling as they fall in still air. Drift fruits and some others are dispersed ...
It is insect pollinated, and sets fruit between March and April. Its seeds are wind dispersed. [1] ... It tolerates flooding but not fire or wind. [1]
