Trillium grandiflorum in the foreground and the smaller Thalictrum thalictroides in the background are both spring ephemerals of North American deciduous forests. An ephemeral plant is a plant with a very short life cycle or very short period of active growth, often one that grows only during brief periods when conditions are favorable.
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 ...
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 ...
Applies e.g. to stele s and flowers in which the perianth segments within each whorl are alike in size and shape. Compare regular. Contrast asymmetrical, irregular, and zygomorphic. aculeate Armed with prickle s, [13] e.g. the stem of a rose. acumen A long, tapering point, especially the apex of an acuminate leaf. acuminate
The synonym Araujia hortorum is in more frequent use in New Zealand. [3] [4] Its common names include bladderflower, white bladderflower, bladder vine, cruel vine, cruel plant, moth plant, moth vine, common moth vine, and false choko. [2] It was introduced to Europe and other areas as an ornamental plant, but it is now considered a noxious weed ...
The flowers are perched on a pedicel (i.e., flower stalk) raising them above the leaf whorl, and grow pinker as they age. [9] [10] The flowers' stigmas are slender, straight or mostly so, narrowing at the end. [6] The white petals are much longer than the green sepals. [6] The flowers have six stamens in two whorls of three, which persist after ...
They naturalise relatively easily forming large drifts. These are often sterile, [60] found near human habitation, and also former monastic sites. [59] The leaves die back a few weeks after the flowers have faded. Galanthus plants are relatively vigorous and may spread rapidly by forming bulb offsets. They also spread by dispersal of seed ...
Dichogamy – flowers that cannot pollinate themselves because pollen is produced at a time when the stigmas are not receptive to pollen. Entomophilous – insect-pollinated. Hydrophilous – water-pollinated; pollen is moved in water from one flower to the next. Malacophilous – pollinated by snails and slugs. Ornithophilous – pollinated by ...
