Some authors include the genus Barclay in the family pitcher. However in the domestic literature it is accepted to allocate Barclay in a separate monotypic family.
Thailand, Burma. The leaves are lanceolate, up to 3-5 cm wide and up to 50 cm long, heart-shaped at the base. Petiole is up to half the length of the leaf, rosette location. The color of the thin leaves is reddish-brown or green, pinkish-purple below. Barclay stands out well among other plants. Barclays requires certain conditions of maintenance: temperature 24-28 °C, clogged warm soil, old water. Water is preferably soft, slightly acidic. The lighting is bright, well, if a few hours a day on the Barclays get direct sunlight. Algae these plants never overgrown.
The plant has a four-week dormancy period when it stops growing and even sheds leaves. At this time, the lighting is reduced, the plant is not disturbed. In nature, the period of rest falls on the dry season. In some streams where Barclays grow, the water disappears completely, and the plant is renewed only from seed. Under good conditions of the maintenance of barclaya regularly gives flowers. The Bud often does not reach the surface of the water. In this case, pollination and fruit development still occur. In order not to lose the seeds, the fruit in advance put on a bag of nylon stockings. Seeds look like small prickly balls. They are separated from the mucus, washed and left in a bowl of water. As soon as the water level drops almost to the seeds, pink sprouts will appear from them. The dried seeds also germinate after pouring the oxygen-rich water. Above the young plants maintain a water level of 1 cm, protect them from shellfish and filamentous algae.
Mollusks and ringed catfish can damage leaf blades in adult plants as well.
Under optimal conditions, a beautiful flower opens on the surface of the water.
