Plant Species of San Jacinto Mountain:
Cystopteris fragilis, brittle bladder fern
Dave has summarized the habitat of this species well:This species seems to be everywhere there is a rock in the water in the San Jacintos and sometimes even without the rock or the water.
Fig. 1 shows the geographic distribution of locations of this species from our surveys, which bears out this summary. Many of the locations are clearly seen to be in drainages that at least seasonally have flowing water, with a smaller number of locations at higher elevation growing in cracks in boulders.
