Botrychium neolunaria

Botrychium neolunaria (New Moon Moonwort)
Ophioglossaceae (Adder's Tongue Family)

Montane, subalpine. Meadows, disturbed areas. Summer.
Road to Sharkstooth Trail, August 24, 2011.

This B. neolunaria has a trophophore just one inch tall and a sporophore nearly 2 inches tall.  Typically the trophophore would be as much as 4 inches tall with a sporophore about twice the height of the trophophore.

Notice that the bottom pinnae (more clearly shown in the next photograph) are much larger than the pinnae above.  Both are fan-shaped.

This species was previously described throughout the northern hemisphere under the name of B. lunaria, which is now considered to be a Canadian and Eurasian species genetically distinct from our B. neolunaria.  This new species description has not been published as of 2011.  Research determining the distinction between the two species was done by Mary Stensvold for her PhD under Don Farrar at Iowa State University in 2008.  Click to read her dissertation. Mary summarizes B. neolunaria as follows:

As with all members of the complex..., [B. neolunaria] is morphologically variable. Compared with other ferns in the complex it tends to have narrow trophophores; pinnae that are approximate to somewhat overlapping, and generally not overlapping the rachis; basal pinnae that span an arc of less than 180 degrees; basiscopic margins of the basal pinnae that are linear to moderately concave....
