State Rank Reason (see State Rank above)
Reported from approximately two dozen sites. Population levels are poorly documented. As this species was not previously tracked in the state, it may be under-reported.
 
General Description
Plants 5–15 cm. Trophophore dark green to yellow-green, triangular, up to 5 cm long, with 1 to 3 pairs of lobed pinnae; the pinnae ascending and not overlapping. Sporophore 1 to 3 times pinnate, 1 to 2.5 times as long as trophophore. According to Farrar (unpublished) our plants are subspecies lanceolatum, although Lesica (2012) indicates that subspecies lanceolatum and the putatively eastern subspecies angustisegmentum are difficult to separate (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX; Donald Farrar (Iowa State Univeristy; unpublished manuscript)).
