Other comments |
As
the fronds are removed for decorative purposes, the cone formation is
affected and thereby affects regeneration. Tender leaves are used as
vegetables. Powdered seeds cooked and eaten like rice cakes. Apical meristem
are cut and used for sago extraction. Antidote for snake poison. In Alagar
Koil, Madurai, the pith is cut, powdered and used for arrack preparation.
Fruits used as aphrodisiac. Plants extremely low growing and dioecious. Often
grown as an ornamental plant. Pith is traded. Proportion global population in
Tamil Nadu is < 5 %. |
