Muhlenbergia8: 94. 1912
Phenology: Sporulating late spring–fall.
Habitat: Cliffs and rocky slopes, on various substrates but rarely observed on limestone
Elevation: 600–2500 m
Most manuals refer to Pellaea truncata as P. longimucronata, a name shown to be invalid by A. Cronquist et al. (1972+, vol. 1). Populations located near the range of P. mucronata in the Mojave Desert are often difficult to identify because of the subtlety of the characters involved and an apparent tendency to produce sterile (and possibly fertile) hybrids. Morphologically intermediate hybrids between P. truncata and P. wrightiana are common in regions where the ranges of the two species overlap, but these are easily identified by their malformed spores.
