Safety & Hazards

Although no specific mention has been seen for this species, it belongs to a family where most of the members contain calcium oxalate crystals. This substance is toxic fresh and, if eaten, makes the mouth, tongue and throat feel as if hundreds of small needles are digging in to them. However, calcium oxalate is easily broken down either by thoroughly cooking the plant or by fully drying it and, in either of these states, it is safe to eat the plant. People with a tendency to rheumatism, arthritis, gout, kidney stones and hyperacidity should take especial caution if including this plant in their diet[1].

Cultivation Details

HabitSemi-deciduous Climber
Growth—

A plant of the fairly dry to moist tropics, where it is usually found at elevations from near sea level to around 1,900 metres[2]. Prefers a moist, well-drained, humus-rich soil and a position in partial shade[3]. Plants are generally low feeders, but do benefit from occasional feeds that are rich in magnesium[3]. Like many species in the family Araceae, this plant has the ability to heat the flowering spadix as the pollen becomes ready for fertilization. This heat greatly increases the strength of the aroma released by the plant, thus attracting more pollinating insects. It can also have the effect of making the insects more active, thus increasing the level of fertilization[3].

Propagation

Plenty in it for both the casual reader and the serious student. Just one main quibble is the silly way of having two separate entries for each plant.
