This dainty little endemic fern is ‘oali’i makali’i (Schizaea robusta). I came across it near the summit of Konahuanui. Interestingly, the frond is mostly made up of just the stipe; the blades are only found the very distal portion. This rather unique look gives it another colloquial name: the toothbrush fern. Keep an eye for it on wet summit and boggy areas.
