Drosera capillaris is a carnivorous plant of the genus sundew ( Drosera ).
description
Drosera capillaris is a perennial, herbaceous plant with a diameter of two to seven centimeters.
leaves
The plant forms a rosette lying flat on the ground. The up to 24 millimeters long and five millimeters wide leaf stalks change into up to twelve millimeters long and four millimeters wide, conversely egg to lanceolate leaf blades. The otherwise green leaves turn red in strong sunlight.
blossoms
Drosera capillaris flowers and produces fruit all year round. One to three hairless inflorescences are formed per plant with a height of up to 21 centimeters and up to fifteen flowers per inflorescence. These stand on short (around one millimeter long) flower stalks, the 1 to 1.5 millimeter long, linear bracts are wine-red.
The flowers are five-fold and up to one centimeter in diameter. The sepals are two to four millimeters long. The petals are pink (in English the species is called "Pink Sundew"), occasionally white. The seed is elongated.
Chromosome number
The number of chromosomes is 2n = 20.
distribution
Drosera capillaris is the most widespread sundew species of the neotropics . It can be found from the southeast of the USA (Texas, Florida, Virginia, but also disjoint in Tennessee) over the Caribbean (Cuba, Jamaica, Puerto Rico, Trinidad and Tobago) to the east coast of Central and South America (Mexico, Belize, Honduras, Nicaragua, Costa Rica, Venezuela, Guyana, Brazil, Paraguay, Uruguay).
