Description
Drosera adelae is a tropical perennial plant that produces long, sword-shaped leaves in a basal rosette. The leaves, like most other Drosera species, are covered with sticky, stalked tentacles that secrete the prey-capturing glue. Tentacle movement in this species, unlike other Drosera, is minimal and slow to the point of being barely noticeable. The leaves are narrowly lanceolate and are typically 10–25 cm (4–10 in) long and 7-10 mm wide. The lower surface of the leaves are glabrous and petioles are either very short or absent. Inflorescences are one-sided raceme and up to 35 cm (14 in) long, bearing many red, reddish orange, or cream coloured flowers from June to November. The five petals produce a perfect pentagon shape.
Drosera adelae reproduces rapidly by asexual means, generating new plantlets from the spreading roots, which means this species is often found in large clumps.
This species has a diploid chromosome number of 2n = 30, though a cultivated cytotype of the species had been reported as having 2n = 28, which botanist Fernando Rivadavia suggested may represent different forms of the species.

Famous quotes containing the word description:
“To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
—Oscar Wilde (1854–1900)
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
“Whose are the truly labored sentences? From the weak and flimsy periods of the politician and literary man, we are glad to turn even to the description of work, the simple record of the month’s labor in the farmer’s almanac, to restore our tone and spirits.”
—Henry David Thoreau (1817–1862)
