Common name
clustering fishtailfishtail:
leaflet shape of some palms appearing like a fish tail, or as if a bite has been taken out of the leaflet, eg. <em>Caryota</em> (see praemorse)
palm
Description
Stem: Clustering, upright, to 7-10 m tall and 12-15 cm in diameter, older palms ringed with slender, widely-spaced leafleaf:
in palms -- the leaf blade (which is usually divided into leaflets or leaf segments), the petiole (or leaf stalk) and the sheath (which forms the attachment of the leaf to the stem)
scars. Leaves: Bipinnate, induplicateinduplicate:
Most palm leaflets or leaf segments are obviously folded. If the folds create a V-shape, with the midrib lower than the margins (so that rain might fall "into a valley"), the folding is induplicate.
, to 7 m long, with dull green, pendulous leaflets growing in one plane. The leaflets are obdeltoid and praemorsepraemorse:
with a jagged edge or like a fish tail
. Flowers and fruit: Inflorescences are up to 0.5 m long with many pendant branches with staminatestaminate:
a flower bearing stamens but no pistils; a “male” flower
and pistillatepistillate:
a flower bearing a pistil but no stamens; a “female” flower
flowers on the same inflorescenceinflorescence:
the reproductive structure of a flowering plant, including palms, consisting of flowers and associated bracts
. Fruits are up to 2.5 cm long and red-orange to black when ripe.

May be confused with
Caryota maxima, but C. maxima is a solitary, single stem palm that ultimately reaches a much greater height
Distribution
Native to India through Southeast Asia to Java and the Philippines
Additional comments
Extreme care is required when handling the fruits, in which calcium oxylate crystals are found.
Individual stems of this palm produce inflorescences from the highest to the lowest node (leaf scar ring) that then mature from the top down. Then the stem dies, but other stems in this clustering palm continue, producing inflorescences and dying in turn.
