The dogwood bunchberry's flower opens its petals and fires pollen in less than 0.5 milliseconds. The record is currently held by the white mulberry tree, with flower movement taking 25 microseconds, as pollen is catapulted from the stamens at velocities in excess of half the speed of sound—near the theoretical physical limits for movements in ...
Mimosa pudica (also called sensitive plant, sleepy plant, [citation needed] action plant, humble plant, touch-me-not, touch-and-die, or shameplant) [3] [2] is a creeping annual or perennial flowering plant of the pea/legume family Fabaceae. It is often grown for its curiosity value: the sensitive compound leaves quickly fold inward and droop ...
It flowers very profusely, [50] and the large flower heads are borne on stalks 5–9 cm (2–3.5 in) above the foliage. Unlike other forms, the stems wither and die naturally after flowering, making way for more new growth and flowers. [51] The flower heads are golden yellow and measure 6 cm (2.5 in) across. [7]
The long and slender fruit capsules can measure up to 35 cm (14 in) and appear from February through April. After the drying fruit dehisces, the anemochorous, hyaline-membrane-winged seeds are released. There are an average of 45,000 seeds per kg with up to 13% water content. Germination of
Two Mexican species - C. macrosepala and C. violacea - have flowers that are cooked and used as vegetables. C. allouia or leren, from the West Indies and tropical America, is known as sweet corn root for its edible tuber. [citation needed] Schumannianthus dichotomus is used for weaving mats to use on floors and beds. [citation needed]
The flowers are produced in late spring to early summer, white in color and on a single spike-like raceme 15–25 cm long on top of a 20–50 cm tall stem. Each individual flower has five petals, and is up to 4 mm (5 ⁄ 32 in) in diameter. The fruit is a small capsule containing numerous seeds.
B. marginata flower spike before and after anthesis. Banksia flowers are usually a shade of yellow, but orange, red, pink and even violet flowers also occur. The colour of the flowers is determined by the colour of the perianth parts and often the style. The style is much longer than the perianth, and is initially trapped by the upper perianth ...
In angiosperms, the mechanism has been studied more extensively as pollen tubes in flowering plants grow very fast through long styles to reach the well-protected egg. There is great variation in pollen tubes in angiosperms and many model plants like petunia, Arabidopsis , lily and tobacco plants have been studied for intraspecific variation ...
