This may explain why, though bees are not observed to visit ragweed flowers, its pollen is often found in honey made during the ragweed floral bloom. Other flowers that are generally anemophilous are observed to be actively worked by bees, with solitary bees often visiting grass flowers, and the larger honeybees and bumblebees frequently ...
Thalictrum fendleri is a perennial herb growing erect to 1–2 metres (3.3–6.6 ft) tall. The hairless stems are green to purple in color. The leaves have compound blades divided into a few or many segments of varying shapes, often with three lobes, and are borne on long, slender petioles.
A few are wind pollinated (anemophilous). There is a distinct calyx and corolla, except in Macleaya where the corolla is lacking. The flowers are medium-sized or large. The terminal flowers are solitary in many species. In others the terminal inflorescence is cymose or racemose. The flowers are odourless and regular.
A catkin or ament is a slim, cylindrical flower cluster (a spike), with inconspicuous or no petals, usually wind-pollinated (anemophilous) but sometimes insect-pollinated (as in Salix). It contains many, usually unisexual flowers, arranged closely along a central stem that is often
Flowers are pale yellow, tubular, and clustered in spherical bent-down heads (capitula), which are in turn clustered in leafy and branched panicles. Flowering occurs from early summer to early autumn; pollination is anemophilous. The fruit is a small achene. Seed dispersal occurs by gravity. [5]
Flowers pollinated by bees and wasps vary in shape, colour and size. Yellow or blue plants are often visited, and flowers may have ultra-violet nectar guides, that help the insect to find the nectary. Some flowers, like sage or pea, have lower lips that will only open when sufficiently heavy insects, such as bees, land on them.
Many flowers, for example, attract only one specific species of insect and therefore rely on that insect for successful reproduction. This close relationship is an example of coevolution, as the flower and pollinator have developed together over a long period to match each other's needs.
Caryophyllaceae, commonly called the pink family or carnation family, is a family of flowering plants.It is included in the dicotyledon order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactaceae, and Polygonaceae. [1]
