Propagation
Collect and sow seed when ripe, keep moist, maintaining a temperature of 25ºC (77º F). Germination normally takes 45 days and the viability period is short.
Do not allow the seeds to dry out before sowing as this slows or inhibits germination.
Division of suckers during spring.
Botanic information
Leaf: The glossy dark green pinnate fronds have evenly spaced linear leaflets with thickened margins, prominent mid-vein and an oblique apex that may be notched. The petiole is long and slender with the base forming a sheath around trunk which is white-woolly when young.
Flower: The yellow-red inflorescence appears below the crown shaft on a short peduncle and in bud it is enclosed with 2- overlapping deciduous tubular bracts, that taper towards the apex.
The rachis is elongated and the branches twice with the flowers arranged in threes, 2-male to 1-female towards the base of the branchlets. They appear during early summer.
Note
The symmetrical male flowers have 3-imbricate sepals and 3-valvate petals with many stamens that have erect filaments and the pistillode is ovoid to elongate.
The female flower has 3-imbricate sepals and petals. They have tiny sterile stamens with a one cell ovary that contains one ovule and has 3-stigmas.
Fruit: The small ovoid to elliptical drupe has a thin purplish-black endocarp and the seeds have 3 to 5 longitudinal groves (sulcate) and have endosperm. The flowering and fruiting period may vary in tropical regions. The small seeds are viable but the plant can be reproduced vegetatively.
