Common Swamp Pitcher Plant

Nepenthes mirabilis is by far the most widespread tropical pitcher plant, ranging from southern China through Southeast Asia and the Malay Archipelago to northern Australia. It is a very variable lowland species of wet, often sandy places.

Nepenthes mirabilis is an erect or climbing plant 0.5-2 m tall. Young plants form a dense rosette of lanceolate leaves about 10 cm long with small, narrowly ovoid pitchers 2-7 cm tall. Leaves on the climbing stem are oblong to lanceolate, 10-25 cm long and often dotted purple-red, with a tendril about as long as the leaf blade. The leaves are usually rather flimsy.

The upper pitchers are cylindrical and slightly widened at the base, 6-21 cm tall, with two fringed wings, a mouth 1.5-5 cm wide and an ovate to oblong lid about 4.5 cm long. The inside of the lower part of the pitcher is glandular and the upper part smooth. Flowers are borne on racemes 20-50 cm long, with four red to purplish-red tepals; like all Nepenthes, plants are either male or female. The seeds are thread-like, about 1.2 cm long.

The species varies greatly across its range and has more synonyms than any other Nepenthes. Two varieties are accepted: var. echinostoma from Brunei and Sarawak, with an extremely broad, flat peristome, and var. globosa from southern Thailand, with squat, rounded pitchers. It is closely related to the three Australian endemics N. rowaniae, N. tenax and N. parvula.

স্থানীয় অঞ্চল: Southern China and Indochina through Malaysia, Sumatra, Java, Borneo, Sulawesi, the southern Philippines, Maluku, New Guinea and Palau to Cape York, Australia

জলবায়ু অঞ্চল: Tropical lowlands; grown under glass outside the tropics

Forests, grasslands, swamps, roadsides and waste ground, usually in wet places and often on sandy soils. In China it grows from sea level to 400 m. It has also been recorded from many small islands across its range. In Borneo var. echinostoma is the only form found in Brunei.

ফাঁদের ধরণ: Pitfall Trap

The pitcher is a pitfall trap formed at the end of the leaf tendril. Insects drawn to the nectar glands of the lid can fall from the slippery peristome into the fluid. The glandular lower part of the inner wall secretes digestive fluid, which can be as acidic as pH 2, while the smooth upper part makes escape difficult. The pitchers host many other organisms, including mosquito and midge larvae, mites, a nematode (Baujardia mirabilis) and diverse bacteria.

It has the widest distribution of any Nepenthes species.
It forms more known natural hybrids than any other species in the genus.
The name mirabilis is Latin for 'wonderful'.
In southern China tree frogs have been seen sitting in the pitchers, feeding on insects the plant attracts without being digested.
The first aquatic fungus recorded living in a carnivorous plant's pitcher was found in N. mirabilis on the Jardine River in Australia.
In Hong Kong it is a protected species under Forestry Regulations Cap. 96A.
The IUCN Red List assessed it as Least Concern in 2014 (Clarke, assessment T49122515A21844202).

Nepenthes mirabilis was first described under the Linnaean system by João de Loureiro, as Phyllamphora mirabilis, in his Flora Cochinchinensis of 1790. Carl Ludwig Willdenow moved it to Nepenthes in 1805 under the illegitimate name N. phyllamphora, and the correct combination N. mirabilis was published by George Claridge Druce in 1916.

The broad-lipped variety echinostoma was found by Odoardo Beccari in 1865 and described as a species, N. echinostoma, by Joseph Dalton Hooker in 1873. The round-pitchered var. globosa was described by Marcello Catalano in 2010, after circulating in the horticultural trade as 'Nepenthes globosa' and 'Nepenthes sp. Viking'.
