Biology
This species is a perennial herb growing from a fleshy
rhizome. It is scandent, climbing using tendrils, the stem reaching 4 meters
long. The leaves are mainly alternately arranged, but they may be opposite, as
well. They are somewhat lance-shaped and tipped with tendrils, and they are up 13
to 20 centimeters long. The showy flower has six tepals each up to 5 to 7.6
centimeters long. They are generally bright red to orange at maturity,
sometimes with yellowish bases. The margins may be quite wavy. The six stamens
also are long, up to 4 centimeters, and each bears a large anther at the tip
that drops large amounts of yellow pollen. The style may be more than 6
centimeters long. One flower may weigh over 2.5 grams. The fruit is a fleshy
capsule up to 6 to 12 centimeters long containing red seeds. Cultivars of this
popular garden plant may vary from these wild-type characteristics; the
cultivar 'Lutea' has all-yellow tepals, 'Citrina' is yellow with red markings,
and 'Nana' is a dwarf. Whitish forms are known, as well.
The plant likely is pollinated by butterflies and sunbirds.
It grows in many types of habitat, including tropical jungles, forests,
thickets, woodlands, grasslands, and sand dunes. It can grow in nutrient-poor
soils. It can be found at as high as 2500 meters in elevation.
Toxicity
This plant is poisonous, toxic enough to cause human and
animal fatalities if ingested. It has been used to commit murder, to achieve
suicide, and to kill animals. Every part of the plant is poisonous, especially
the tuberous rhizomes. As with other members of the Colchicaceae, this plant
contains high levels of colchicine, a toxic alkaloid. It also contains the
alkaloid gloriocine. Within a few hours of the ingestion of a toxic amount of
plant material, a victim may experience nausea, vomiting, numbness, and
tingling around the mouth, burning in the throat, abdominal pain, and bloody
diarrhea, which leads to dehydration. As the toxic syndrome progresses,
rhabdomyolysis, ileus, respiratory depression, hypotension, coagulopathy,
haematuria, altered mental status, seizures, coma, and ascending polyneuropathy
may occur. Longer-term effects include peeling of the skin and prolonged vaginal
bleeding in women. Colchicine is known to cause alopecia. One case report
described a patient who accidentally ate the tubers and then experienced hair
loss over her entire body, including complete baldness. Poisonings can occur
when the tubers are mistaken for sweet potatoes or yams and eaten. The plant
can be dangerous for cats, dogs, horses, and livestock, as well.
