Howea: The Majestic Sentinels of Lord Howe Island
Howea, a genus of flowering plants belonging to the Arecaceae (palm) family, is renowned for its elegant, feather-like fronds and its ability to thrive as an indoor plant. Native exclusively to Lord Howe Island, a small, crescent-shaped island in the Tasman Sea, Howea palms have captured the hearts of plant enthusiasts worldwide. This article delves into the botany, cultivation, and cultural significance of these remarkable palms.

Botanical Characteristics and Classification
The genus Howea comprises two species: Howea forsteriana (Kentia palm) and Howea belmoreana (Sentry palm). Both species are endemic to Lord Howe Island, showcasing the island’s unique biodiversity.
Howea forsteriana (Kentia Palm):
This species is characterized by its graceful, arching fronds and relatively robust trunk.
It can reach heights of up to 10 meters in its natural habitat, although indoor specimens remain considerably smaller.
The pinnate leaves are comprised of numerous leaflets, creating a lush, feathery appearance.
The flowers are small and inconspicuous, followed by reddish-brown fruits.
Howea belmoreana (Sentry Palm):
Distinguished by its more upright, rigid fronds, Howea belmoreana presents a more formal appearance.
Its trunk is typically slender, and it grows to a slightly smaller stature than Howea forsteriana.
The leaf structure is similar to the Kentia palm, with pinnate leaflets.
The fruits are also reddish-brown.
