cycad ...


world distribution of cycadales

overall species diversity peaks at 17˚N and 28˚S, with a minor peak at the equator. there is therefore not a latitudinal diversity gradient towards the equator but towards the tropics.

yep, it is a kind of palm, a sago palm. found only in the south india, and its listed in the RED LIST as ENDANGERED. botanically named as "Cycas circinalis"

The plants contain alkaloids of carcinogens and also an amino-acid that causes chronic nervous disorders. Regular consumption of the plant leads to severe health problems and death. This toxic principle can be removed if the food is properly prepared but consumption of the plant still cannot be recommended because its use often means the death of the plant and it is becoming rare in the wild.

An evergreen shrub growing to 3.5m at a slow rate. It is in leaf all year. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant) and are pollinated by Insects and wind. It can fix Nitrogen.

The pith is rich in carbohydrate and a sago can be made from it. This use will kill the plant.

The raw seed is poisonous, but after being cut into thin slices, dried, then steeped in water for a few minutes and dried again, it becomes edible. It can be used as a sago.

The very young leaves are edible.

The pollen is narcotic.

The bark and the seeds are ground to a paste with oil and used as a poultice on sores and swellings.

The juice of tender leaves is useful in the treatment of flatulence and vomiting.
