Sadleria cyatheoides (Ko`olau summit ridge form). Hawai`i, O`ahu, Ko`olau Mountains, Ko`olau summit ridge, Hālawa-Ha`ikū section. Patch 1.
Sadleria cyatheoides Kaulf. (Ko`olau summit ridge form)
Hawaiian name: `ama`u, ma`u, ma`uma`u
Family: Blechnaceae
Native. Restricted to the Ko`olau Mountains?
Near the end of the Hālawa Ridge Trail I saw this patch of S. cyatheoides and a few other patches of the species. I do not recall noticing S. cyatheoides occurring on the Ko`olau summit ridge prior to seeing these plants. The species as a whole seems to be less common on O`ahu than it is on all of the other main Hawaiian Islands. As far as I can recall, plants of S. cyatheoides I have seen on O`ahu aside from these plants at the end of the Hālawa Ridge Trail have been in habitats considerably drier than the Ko`olau summit ridge. The photographed plants look different from other plants of S. cyatheoides I have seen on O`ahu. The plants are shorter, their stipes are shorter, and the plants possibly have fewer scales than typical S. cyatheoides plants.
