General Information

Ilex dipyrena is an evergreen shrub or tree growing, usually growing from 2 - 15 metres tall, with occasional specimens to 25 metres[, ]. There is a report of one old and very large tree in India that had a bole diameter of 150cm[].
The plant is harvested from the wild for local use as a source of materials and possibly also as a food. It is sometimes grown as an ornamental.

Known Hazards

Although no specific reports of toxicity have been seen for this species, Ilex species in general contain several potentially toxic compounds, particularly saponins, glycosides and triterpenoids. These compounds also often have a range of potential health benefits[, , ].
The berries are usually the part of the plant most likely to be toxic, though the degree of toxicity is usually low. Their bitter flavour usually prevents a person eating more than one or two, but even a small handful of the fruit eaten by a healthy adult is unlikely to cause more than feelings of nausea that can lead on to vomiting and diarrhoea[].
The compounds in the leaves are particularly interesting. The leaves of many Ilex species around the world are commonly used to make health-promoting teas that, when drunk on a regular basis, help to regulate bodily functions and can reduce the risk of heart disease, lower blood-cholesterol levels etc (See Ilex paraguariensis or Ilex kaushue for examples)[]. Even these teas, however, if taken in very concentrated doses, can act as a laxative or cause vomiting. Indeed, several species are used by traditional peoples to induce vomiting as a means of purifying the body (see Ilex guayusa or Ilex vomitoria for examples)

Cultivation Details

A plant mainly of moist areas in the warm temperate and subtropical zones, extending into the tropics at higher elevations. It is found at elevations from 1,500 - 3,350 metres. It grows best in areas where annual daytime temperatures are within the range 20 - 27°c, but can tolerate 5 - 31°c[]. Mature plants can be killed by temperatures of -3°c or lower, but young growth can be severely damaged at -1°c[]. It prefers a mean annual rainfall in the range 1,500 - 2,300mm, but tolerates 1,000 - 2,800mm[].
Prefers moderate shade, but tolerates full sun and deep shade[]. Succeeds in a range of well-drained, fertile soils[]. Prefers a pH in the range 4.5 - 5.5, tolerating 4 - 6.4[].
Plants can be cut back and will resprout from old wood[].
A dioecious species, both male and female forms need to be grown if fruit and seed are required.
