B. lamellata is a carnivorous plant species of the genus byblis in the family of byblis plants (Byblidaceae). It wasfirst describedin 2002 by Allen Lowrie and John Godfrey Conran and is one of the two perennial, Western Australian Byblis species, whichare summarizedas the " Byblis gigantea complex".
features
Byblis lamellata is a perennial, mostly unbranched subshrub and grows from a thick and fleshy rhizome . It reaches a height of up to 60 centimeters, making it one of the largest representatives of the genus.
Byblis lamellata grows and blooms in winter, and its habitats dry out over summer. The plants survive this time underground, they die above ground and only sprout again from the rhizome or through above-ground shoots with the first rainfall in autumn.
leaves
The yellowish-green leaves are two to four centimeters long, linear, kidney-shaped in cross section and end in a thickening at the tip of the leaf. They are hairless on the surface, but densely populated with stalked glands on the edges and underside that secrete a sticky fluid.
blossoms
From the leaf axils , flower stalks grow above the base of the leaves , which hardly differ from the leaves, but are significantly shorter at 15 centimeters. At their tips between September and January (in the Australian summer) terminal five-fold individual flowers bloom, but only a few at the same time.
The lanceolate, hairy sepals are 8 to 15 millimeters long and 2.5 to 3.5 millimeters wide at the base. The inverted egg-shaped petals are 15 to 20 millimeters long and up to 15 millimeters wide and serrated on the outer edge. They are light to dark purple; white or cream-colored blooming specimens are extremely rare. The stamens are 2.5 to 3.5 millimeters, the anthers 5 to 6 millimeters long and yellow with a brown tip. The white stylus is 7 to 9 millimeters long.
Byblis lamellata only releases its pollen through the sound frequency of an approaching pollinator.
Fruits and seeds
The 5 to 7 millimeter long and 3.5 to 4 millimeter wide seed capsule is broadly ovate and bifacular; when it dries out, it gradually tears open, so that the seeds it contains fall to the ground. The black, 1 to 1.8 millimeters long seeds are furrowed like lamellae. The species is pyrophilic , the germination inhibition of the seeds is only lifted by substances in the smoke of the annual bush fires.
Distribution and habitat
The species has a small range in Western Australia , it is endemic to Eneabba , just under 100 kilometers north of Perth . It grows in heathland or white sand.
Systematics
Byblis lamellata was only separated from Byblis gigantea as a separate species in 2002 . The decisive factor was the differences in the shape of the seeds; while the seeds of Byblis gigantea are furrowed lengthways with clearly protruding elevations, those of Byblis lamellata are furrowed like lamellae. The disjoint distribution areas, the different re-emergence and varying site conditions serve as further diagnostic features. Byblis lamellata prefers drier habitats than Byblis gigantea .
