At least 8,500 different plant species grow in the differing habitat blocks of the GLNP. In the swamp forests, you may find Casuarina trees (Casuarina sp), wild nutmeg (Myristica sp), Mangrove trees, and Pandan (Pandanus sp), as well as Matoa (Pometia pinnata) growing alongside rivers.

In lowland forest, meranti (Shorea sp), kerung (Dipterocarpus sp), and several wild fruit trees including durian (Durio zibethinus), mango (Mangifera indica)and wild banana and an abundance of citrus fruit and wild jack fruit.

In the mountainous areas several species of mosses and flowers grow, and wild orchids are found. Rafflesia arnoldii also grows here.

Rafflesia (Rafflesia arnoldii)
The corpse flower
This is the world's largest individual flower, found only in Sumatra and Borneo. It can weigh as much as 11kg when fully grown, with its red and pink petal growing up to 1m long. The plant is parasitic, lacks any leaves, stems or roots. It obtains its nutrients from host plants which it attaches itself to. Its name 'corpse flower' is from the pungent smell it emits to attract pollinating insects in the dense forest.

Titan arum (Amorphophallus titanum)
The titan arum stands at 1.8m tall, surrounded by an unfurling, maroon and green petal-like mantle. This elusive flower only blooms for a few days before collapsing under its own weight. It is endemic to the Sumatran forests.
