FLORA OF ICELAND elements: Botrychium species, Moonwort species

Some notes on other moonworts on Iceland.
 Botrychium simplex (Glossy Moonwort) is found mainly in the south of Iceland, often near the coast. It is a very small moonwort, usually only having 1 pair of side lobes and an end lobe on the vegetative part of the leaf. The generative part of the leaf far extends the small vegetative part.
 Botrychium boreale and Botrychium lanceolateum. Both species have incised leaf-blades. B. lanceolatum even more so than B. boreale.
 Botrychium minganense. Very much like the common B. lunaria. It is an American species. It can best be characterized by the leaflets not or hardly (at the top) overlapping. Another difference concerns the first pair of leaflets. In B. lunaria they are more or less faced towards the "stem" of the fertile leaf-segment (see photos). In B. minganense they lie in the same plane as the other leaflets.
 Botrychium nordicum. Only recently identified as a new species. It is like the common moonwort (B. lunaria). The leaflets are slanted placed on the "stem" and the base of the leaf is white in stead of green.
 With the exception of B. simplex, the species listed above are rare or even extremely rare. For more information. For more information see http://www.floraislands.is/burknar.html and check out species with an Icelandic name ending in (l)jurt.
