Some are are attracted to big, showy, flashy things: complex constructions, granite countertops, walk-in closets, and en suite bathrooms. Some prefer the muted, the relatively insignificant, mea (objects) that can disappear into the background: single-walled cottages with rickety steps, fading paint, and formica countertops.
This monthʻs meakanu ʻāpaʻakuma is the latter. Easy to overlook. Just another greenish thing growing on a tree trunk in a wet forest along with mosses, other ferns, lichens, liverworts – all also mostly small, but ecologically important.
In 1840-41, the United States Exploring Expedition, commanded by Charles Wilkes, visited Kauaʻi, Oʻahu, and Hawaiʻi, where they surveyed Mokuʻāweoweo atop Maunaloa.
During their visit to Kīlauea, they noted, and collected, a small fern, about 4 inches long, growing on tree trunks. The same fern, kihi (Adenophorus haalilioanum), was also found on Kauaʻi and on Oʻahu.

It was a new species, and was named “In memory of M. (sic) Haalilio, an intelligent chief of the Sandwich Islands, who visited this country (America) a few years ago, and died soon after his return to his native country.” Timoteo Haʻalilio was on a diplomatic mission for Kauikeaouli, and died at sea, off the east coast.
As with many endemic plants, we donʻt know of a particular use, or even the specific name of this kihi. Sadly, so much information has been lost, making it all the more important for all of us to noho i waho, a maliu. Be outside. Pay attention.
