Genus is endemic to Hawaiian Islands. Often found growing in moss on Ohia (Metrosideros polymorpha) tree trunks and associated with Sphaerocionium lanceolatum ferns. Elevation approximately 3870ft/1180m. The University of Hawaii Rainfall atlas estimates annual rainfall at around 105 inches for this location.

This has become a very rare and endangered fern in a genus endemic to the Hawaiian Islands. Originally known from all of the major Hawaiian Islands, now it is only found in Glenwood on the Big Island and in a few small populations on Kauai. According to USFWS, the population has declined rapidly (2009), with over 1200 individuals in the 1990's and now only 51-123 individuals in 2009. In my limited perspective, this species is on the brink of extinction.

This has become a very rare and endangered fern in a genus endemic to the Hawaiian Islands. Glenwood on the Big Island is supposed to have the largest population of Adenophorus periens, with 30 plants found in 1998. I have only found 1 plant on 3 trips in this area, during 2012-2013. In the most recent USFWS status report in 2009, only 51-123 plants are known to exist in all the Hawaiian Islands. In my limited perspective, I would venture that this species is on the brink of extinction.

Genus is endemic to Hawaiian Islands and found on all major islands. Note pinnatifid basal acroscopic pinnules; a few of the other pinnules are slightly divided. Species is extremely variable, but key characteristics are the long-creeping rhizome, epigeous growth from moss mats near base of tree and fronds which are often 3-pinnate.

One characteristic of A. tamariscinus is the short-creeping rhizome which creates a cluster of fronds as in this photo. Elevation around 3300ft/1006m. This forest along the Stainback highway is lush and receives around 250 inches of rain per year.
