Pacific Oakfern (Gymnocarpium disjunctum): Common deciduous fern found in most productive forests, often in large colonies in riparian forest. Expected throughout the region, apparently only a few collections from both the south and north, but none in the central part (seems likely there are older collections still labeled G. dryopteris). Hybrids with G. dryopteris should be expected.
