Ophioglossaceae

From Natural History of Southeast Alaska
Jump to: navigation, search

A significant amount of study has been done on this family over the past 30 years and much of the most recent work is not reflected in the major floras relevant to this region. Also, the distribution of many species poorly known in Southeast Alaska.

A good reference for what is currently known about this group in North America can be found here: http://www.public.iastate.edu/~herbarium/botrychium.html

Scientific NameCommon NameSummary
Botrychium alaskenseAlaska GrapefernExpected in to occur in the region, though it is unclear which parts of it, and where (if?) it has been collected in Southeast Alaska. This species was described in 2002 (?) and is so far known to occur only in Alaska and Yukon Territories.
Botrychium ascendensTriangle-lobe MoonwortDescribed in 1986 and known in our region from beaches of the Yakutat Forelands, this species has a scattered distribution across North America and may be present elsewhere in the region.
Botrychium campestreSlender MoonwortApparently rare throughout much of its range, this species has been found near Yakutat.
Botrychium hesperiumWestern MoonwortMay occur in the far northern mountains along the border with Canada (see map on the pdf linked in references).
Botrychium lanceolatumLance-leaved GrapefernMay be expected throughout the region, but so far apparently collected only on the northern mainland between Yakutat and Haines.
Botrychium lunariaMoonwortExpected to occur throughout the region, it appears most collections are from on or adjacent to the northern mainland, with a collection from Lisanski Strait and another from Coronation Island being exceptions.
Botrychium minganenseMingan MoonwortExpected throughout the region, apparently collections in Southeast Alaska so far have only been made from northern Chichagof Island and the northern mainland from Lynn Canal west to Yakutat.
Botrychium montanumMountain MoonwortApparently found near the northwestern-most edge of the region. This species has also been found to the south in BC, and may occur elsewhere in the region, though its small size may make it easily to overlook.
Botrychium neolunariaCommon MoonwortSpecies not yet formally described. (See pdf linked below for more) Expected throughout the region.
Botrychium pedunculosumStalked MoonwortNot currently known from Southeast Alaska, the nearest report of this species appears to be from British Columbia a ways inland from Prince Rupert. There is also a population that has been found well to the west on the Alaska Peninsula.
Botrychium pinnatumNorthwestern MoonwortExpected throughout the region, there are apparently currently very few collections of this species from Southeast Alaska (mostly out of Haines). This species has been considered at subspecies of B. boreale and may be labeled as such in herbarium records.
Botrychium spathulatumSpatulate MoonwortKnown from stabilized maritime sand dunes on Kruzof Island this species may be expected to occur elsewhere in the region. It is quite similar in appearance to Triangle-lobe Moonwort (Botrychium ascendens) (see pdf linked below for a table of characters used to differentiate the two).
Botrychium tunuxMoosewortThis recent described species is known from the Yakutat area. Previously considered part of B. neolunaria (though B. neolunaria is not yet formerly described - so perhaps this should be B. lunaria?)
Botrychium yaaxudakeitGiant MoonwortDescribed in 2002 from collections made at sandy beaches near Yakutat. Plants of this species had formerly been considered B. neolunaria.
Botrypus virginianusRattlesnake FernScattered collections from Coronation Island north, though coastal collections to the south suggest this species could be expected to occur infrequently throughout much of the region.
Sceptridium multifidumLeathery GrapefernExpected throughout the region, though so far apparently reported no further south than Baranof Island and Admiralty Island (though there are many reports from Haida Gwaii and other locations in coastal BC).
