Saribus rotundifolius

Botanical Background and History

Saribus rotundifolius is a wet-tropical fan palm native from the Banggi Islands off northern Borneo east to Raja Ampat in western New Guinea. It grows in forest and coastal lowlands, where its flowers feed insects and birds disperse the fleshy fruits.

For many years it was known as Livistona rotundifolia, a name that remains familiar in horticulture. Modern classification places it in Saribus, and long cultivation explains why planted populations also occur beyond its confirmed native range.

In the Philippines it is known as anáhaw. Its fan leaves have traditionally been used for thatching and wrapping, and their outline is widely recognised there as an unofficial national symbol.

Care for palms in containers

Light, settling in and temperature: Give Saribus rotundifolius abundant filtered light, introducing gentle direct sun gradually after delivery. In a dark position, young palms produce weak elongated petioles. Keep the root ball warm and frost-free, since cold wet roots can stall the central spear. Moderate to higher humidity helps new fans unfold when air can still circulate.

Root care and watering: Use a deep, aerated palm mix that holds some moisture but drains freely. Water thoroughly when the surface begins to dry, then empty all collected water. Do not let a juvenile root ball dry repeatedly until the fan leaves begin folding, yet constant saturation deprives the roots of oxygen. Water use falls sharply in the darker season, so judge the deeper mix and pot weight rather than following a fixed interval.

Feeding, repotting and propagation: Apply a modest complete palm fertiliser with micronutrients while new leaves are extending, then reduce or stop feeding when growth pauses. Repot only after roots have occupied the container, keep the root ball as intact as possible and leave the stem base at its original depth. Remove only fully dead fronds. This solitary palm cannot be topped, divided or restarted from a trunk because its single growing point does not regrow after removal; propagation is by seed.

Saribus: Warning Signs and Recovery

A centre spear that stalls, smells sour or pulls free from a soft crown is a serious sign of cold and wet damage. Keep the palm warm, prevent water from sitting in the crown and make sure the pot drains freely. Remove only tissue that is fully dead. This palm has a single growing point, so a destroyed crown cannot be replaced by a new branch.

Mite feeding produces pinprick fading or bronzing across the fans. Scale looks different, forming fixed raised covers on the blades, leaf stalks or folded bases. Keep an affected palm apart from nearby plants. Apply treatment only as directed on the chosen product’s label. Brown tips without insects may come from damaged roots or accumulated salts. Check the roots first; if salts are involved, use water with fewer dissolved minerals and rinse the mix only when drainage is good.

Rows of holes that appear as a new fan opens, sawdust-like material in the crown or visible tunnels can point to a palm borer. Keep the palm separate and seek professional plant-health help. Pleated fans, brown fibres and some splitting along mature segments are normal while the surrounding tissue stays firm.

Keep Saribus rotundifolius away from children and pets

• Keep this plant away from children, cats and dogs.
• Its effects after chewing or swallowing are unclear, and plant material can still cause an upset stomach.
• Contact a veterinarian or medical professional if symptoms develop or do not settle.

Who first published Saribus rotundifolius, and what does the name mean?

Saribus preserves the Maluku vernacular name sariboe, which was adopted into botanical Latin. The epithet rotundifolius joins Latin rotundus, meaning round, with folium, meaning leaf.

Carl Ludwig Blume established the genus Saribus in 1838 in Rumphia, volume 2, page 48.

Jean-Baptiste Lamarck first described it as Corypha rotundifolia in 1786 in Encyclopédie, volume 2, page 131. Carl Ludwig Blume later placed it in Saribus as Saribus rotundifolius in 1838 in Rumphia, volume 2, page 49.
