Sundews are carnivorous plants with sticky glands that trap and digest insects. The spelling of the word "sundews" is /ˈsʌnˌdjuːz/, with the emphasis on the first syllable. It begins with the voiced alveolar fricative /z/ sound, followed by the short vowel sound /ʌ/ and the nasal vowel sound /n/. The second syllable starts with the voiced palatal fricative /j/ sound and ends with the long vowel /uː/. The plural "s" indicates that there is more than one sundew.
Sundews are a type of carnivorous plant belonging to the Droseraceae family, primarily found in areas with wet and acidic soils. They are characterized by their unique ability to trap and digest small insects and other arthropods.
The sundew plant gets its name from the sticky, dew-like droplets that adorn its long, hair-like appendages called tentacles. These tentacles emerge from the surface of the plant's leaf, and each is covered in tiny, glandular hairs that produce a sticky mucilage. These droplets glisten in the sunlight, acting as a lure for unsuspecting prey.
When an insect or small arthropod comes into contact with the sticky droplets, it becomes ensnared and unable to escape. The sundew's tentacles then slowly move toward the trapped prey, further enveloping it in a sticky embrace. The plant's digestive enzymes are released onto the prey, breaking it down into nutrient-rich compounds that can be absorbed by the sundew's leaves.
Sundews are mainly found in nutrient-poor environments, and the ability to supplement their diet with insects allows them to obtain vital nutrients such as nitrogen and phosphorus. This adaptation has allowed sundews to thrive in habitats that would otherwise be unfavorable for plant growth.
Sundews are considered fascinating and unique plants due to their carnivorous nature, which sets them apart from the majority of the plant kingdom. Their captivating appearance and ingenious trapping mechanisms make them a popular choice among plant enthusiasts and researchers alike.
The word "sundews" derives from the Middle English term "sundew", which can be traced back to the Old English "sundēage" or "sōgdēage". These terms were compound words combining "sunne" (sun) and "dēage" (dew), meaning "dew of the sun". This etymology highlights the way the droplets of the sundew plant's sticky secretion resemble glistening dewdrops in the sunlight.
