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.
Larvae of the foxglove pug, a moth, consume the flowers of the common foxglove for food. Other species of Lepidoptera eat the leaves, including the lesser yellow underwing. [20] The shape of the foxglove's flowers makes it especially attractive to long-tongued bees, such as the common carder bee. The bright flowers attract the bee, which lands ...
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
Gaillardia / ɡ eɪ ˈ l ɑːr d i ə / [3] (common name blanket flower) [4] is a genus of flowering plants in the family Asteraceae, native to North and South America. It was named after Maître Gaillard de Charentonneau, [ 5 ] [ 6 ] an 18th-century French magistrate who was an enthusiastic botanist .
The basal portion of the flower there is a cavity that houses the white ovules that will mature into seeds. [3] Insects that pollinate the flowers do so by burying themselves in the sepals of the flowers through the very strong fibres that hold the sepals together. After the insects have been in the flowers for a couple of days, the flower ...
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 ...
[1] [6] The flower stem is known as a pedicel, and those flowers with such a stem are called pedicellate, while those without are called sessile. [7] In the angiosperms, the flowers are arranged on a flower stem as an inflorescence. Just beneath (subtended) the flower there may be a modified, and usually reduced, leaf, called a bract.
During the night, the flowers may assume a random orientation, while at dawn they turn again toward the east where the Sun rises. The motion is performed by motor cells in a flexible segment just below the flower, called a pulvinus. The motor cells are specialized in pumping potassium ions into nearby tissues, changing their turgor pressure.
