On a bank in forest north of Casadero along the road to the Cedars but not in the serpentine area (Sonoma County, California, US). This is a fairly dissected form of P. californicum but is not dissected enough to be P. dudleyi and has narrower fronds than that species. Image I12-0437, Feb. 4th 2012.
This uncommon Botrychium species was first found in California in 2010, at a site in forest on the western slope of the central Sierra Nevada. It is seen here at that location where I was shown it in 2011, in a semi-open spot associated with conifers and Fragaria virginianum (see the red stawberry at the left of the image). The plants were smaller than I have seen them at Lostine Canyon in Oregon. The identification has been confirmed by Don Farrar using isozyme analysis. August 27th 2011, image I11-9905.

Hpuu or Hpuu meuCibotiaceae (Tree fern family)Endemic to the Hawaiian Islands (common on Oahu; uncommon to scattered on Molokai, Lnai, Maui and Hawaii Island)Aiea Loop Trail, OahuHawaiians, both long ago as well as in recent times, ate the uncoiled fronds (fiddles), which were considered delicious when boiled. Likely the starchy core of this species, as with hpuu pulu and hpuu ii, was used as an important famine food. One trunk may contain 50-70 pounds of almost pure starch and would have been used for human as well as pig consumption. It was prepared by peeling the young fronds or placing the entire trunk with the starchy center in an imu or in steam vents at the volcano.EtymologyThe generic name Cibotium is from the Greek kibotion, diminutive of kibotos, a box or casket, in reference to the indusium, a part of the fern blade that covers the sorus (spores).The specific name, chamissoi, named for Ludolf Karl Adelbert von Chamisso (1781-1838), French-born German explorer, naturalist, author, poet, and plant collector.NPH00017www.nativeplants.hawaii.edu/plant/view/Cibotium_chamissoi
