Common name
Chinese fan palm
Description
Stems: Solitary, erect, gray or brown, to 12 m in height and 25 cm in diameter. Old leaves persist on the stem, leaving closely spaced rings of 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 when they fall away. Eventually the rings wear away to leave a relatively smooth (corky toward the base) stem. Leaves: Costapalmatecostapalmate:
a fan-shaped leaf with a midrib (costa) extending into the blade, sometimes extending far enough into the blade to cause it to curve (e.g., <em>Sabal palmetto</em>)
, with a prominent hastulahastula:
a flange or collar-like flap of tissue extending from the petiole where a palmate leaf blade joins it; often seen on the upper (adaxial) surface, but may also be found on the lower (abaxial) surface in some palms
, 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.
, dull olive green, up to 2 m across, and divided to about two-thirds its length into stiff segments with drooping, bifidbifid:
deeply cleft into two usually equal parts or two-lobed from the apex; for example, palms with bifid leaves or leaflet tips (e.g., <em>Chamaedorea metallica</em> has bifid leaves)
tips. The petioles are armed with robust marginal teeth toward the base (sometimes lacking these teeth). Flowers and fruit: The inflorescences are 1-1.5 m long and branched to five orders. Flowers have both male and female structures, pale yellow. The fruit is ovoid, about 2 cm across, and greenish to grayish blue when mature.

May be confused with
Other Livistona species, but L. chinensis has blue fruit. L. australisis taller with more robust 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 and deep green leaves.
Distribution
Native to China, Southern Japan
