Template:Short description Template:Speciesbox
Triphyophyllum peltatum is a facultatively carnivorous,[1] up to 60 m tall vine[2] in the monotypic genus Triphyophyllum Template:IPAc-en in the family Dioncophyllaceae native to tropical western Africa, in Guinea, Ivory Coast, Liberia, and Sierra Leone[3] where it grows in tropical rainforest.[2]
Description
Vegetative characteristics
It is a facultatively carnivorous,[1] heterophyllous,[4] up to 60 m tall vine[2] with glabrous, terete stems.[5] It has a three-stage lifecycle, each with a different shaped leaf, as indicated by its Greek name. In the first stage, T. peltatum forms a rosette of simple lanceolate Dracaena-like leaves about Template:Cvt in length with undulate margins. At times when there is insufficient phosphorus in the soil[6][7] it develops long, slender, glandular, circinate leaves up to Template:Cvt in length and bearing two sorts of glands, and resembling those of the related Drosophyllum, which capture insects; there being one to three of these leaves in each rosette.[8] In the plant's adult liana form it has short non-carnivorous leaves bearing a pair of "grappling hooks" [9] at their tips on a long twining stem which can become Template:Convert in length and Template:Convert thick.[10][11] T. peltatum is the largest of all confirmed carnivorous plants in the world, but its carnivorous nature did not become known until 1979, over 50 years after the plant's scientific description.[4]
Generative characteristics
The axillary,[12][13] branched,[14] cymose, few-flowered[13] or many-flowered inflorescence bears up to 80 small, ephemeral,[14] fragrant,[12] white to pink,[14] bisexual, actinomorphic, pedicellate flowers.[13] The pedicel is up to 3 cm long. The flower has 5 triangular, 2 mm long sepals, and 5 obovate, 13 mm long petals.[13] The androecium consists of 10 stamens.[13][5] The style is very short.[5] The up to 4 cm wide, 1-seeded,[13] 4–5-valved capsule fruit[5][13] bears discoid, papery,[13] flat, winged, circular, pink to red,[12] 5–8[5](–10) cm wide seeds[15][12] with an up to 5.5 cm long funiculus extending beyond the fruit.[13] Most of the seed's development occurs outside the fruit.[16] The seeds are wind-dispersed.[5][17]
Cytology
The chromosome count is 2n = 24,[5][13] 36.[13]
Taxonomy
Triphyophyllum peltatum was first described as Dioncophyllum peltatum Template:Au by John Hutchinson and John McEwan Dalziel in 1927.[18] It was moved to a new monotypic genus Triphyophyllum Template:Au as Triphyophyllum peltatum Template:Au by Herbert Kenneth Airy Shaw in 1952.[3][18]
Etymology
The generic name Triphyophyllum is derived from triphyes meaning of threefold form,[19] and phyllum meaning leaf.[20] It refers to the three growth stages of the plant with three different types of leaves.[6] The specific epithet peltatum means shield-like[21] and refers to the discoid seeds,[17] which have a long stalk that extends the seed beyond the capsule fruit.[13]
Distribution and habitat
Triphyophyllum is found in Guinea, Ivory Coast, Liberia, and Sierra Leone,[3] where it occurs in primary[5] and old secondary dry evergreen rainforests. The habitat has a 6–7 month dry season. The acid, nutrient-poor soil is shallow.[4]
Conservation
It is a rare and endangered species.[6]
Cultivation
Triphyophylum peltatum is difficult to cultivate.[6][22] It is cultivated in several botanical gardens: Würzburg, Hannover,[23] Abidjan, Bonn, Cambridge University and WürzburgScript error: No such module "Unsubst"., and is exceedingly rare in private collections.
Uses
Triphyophyllum peltatum is traditionally used in folk medicine in the treatment of elephantiasis,[13][5] and malaria.[5] It produces many pharmaceutically active secondary metabolites, some of which have been found to have strong antiplasmodial activity. Some metabolites were found to have antitumoral and anti-multiple myeloma activity.[6] The stems are used as tying material.[13]
