Special Features and Information

General Information

Brake ferns ( Pteris spp.) belong to Pteridaceae, one of the largest fern families. Hillebrand’s brake fern ( Pteris hillebrandii ) is one of five (2 indigenous; 3 endemic) species native to the Hawaiian Islands.

Etymology

The generic name Pteris is from the Greek pteris , fern, from pteron , wing, feather, in reference to the frond shape. An ancient name for ferns in general.

The specific epithet hillebrandii is named in for William Hillebrand (1821-1886), a young Prussian physician and plant collector. He planted many of the plants he collected at Queen’s Hospital and on his own property in Nuʻuanu. After moving back to Germany the property was sold to his neighbors Thomas & Mary Foster. Today, it is known as the Foster Botanical Gardens.

Hawaiian Names:

There are no known Hawaiian or vernacular (common) names for this species. But Hillebrand’s brake fern, an apropos name of an unknown source, has been used.

Background Information

This Pteris is currently considered as an endemic species, but it is probable that this species is a hybrid of ʻōali Pteris cretica (indigenous) and mānā P. irregularis (endemic).*

There are also two naturalized species. The ubiquitous, often weedy, Chinese brake fern or Ladder brake ( Pteris vittata ) can be found growing in many residential yards, usually coming up as a volunteer plant, and some times even intentionally cultivated by the homeowners.


  • Also called ʻae, ʻāhewa (Oʻahu), ʻiwa puakea (Maui)

Early Hawaiian Use

None known.

Modern Use

This wonderful fern adds a unique texture in the landscape in shady or part sunny areas especially among other ferns or as part of the understory of larger shrubs and small trees. [David Eickhoff, Native Plants Hawaiʻi]
