Drosera dilatato-petiolaris
Encyclopedia
Drosera dilatato-petiolaris is a carnivorous plant
in the genus Drosera and is endemic to Australia
, being found in both Western Australia
and the Northern Territory
. Its leaves are arranged in a rosette
and commonly produces plantlets, eventually forming large clumps that can be over 1 ft (0.3048 m) across. Green petiole
s emerging from the center of the rosette are typically 3–5 mm wide, but can vary. Red carnivorous leaves at the end of the petioles are small and round, with most resting on the soil surface. Inflorescence
s are 18 cm (7 in) long with white flowers being produced from April to May. It has a diploid chromosome number of 2n = 12.
Drosera dilatato-petiolaris is found in damp sandy soils on higher ground than Drosera petiolaris
is found. It's native to coastal areas near Darwin
in the Northern Territory and the northern Kimberley region of Western Australia. It was first recognised and illustrated by Ludwig Diels
in his 1906 monograph on the Droseraceae
, but was not formally described until 1984 when Katsuhiko Kondo authored three new species in the Drosera petiolaris complex.
Carnivorous plant

Petiole (botany)
In botany, the petiole is the stalk attaching the leaf blade to the stem. The petiole usually has the same internal structure as the stem. Outgrowths appearing on each side of the petiole are called stipules. Leaves lacking a petiole are called sessile, or clasping when they partly surround the...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Strictly, it is the part of the shoot of seed plants where flowers are formed and which is accordingly modified...
