Discusión taxonómica
Woodsia plummerae is distinct in being extremely glandular, the glands often expanded at tip and yellowish. The adaxial surfaces are dull and have no projections. The stipe bases are dark for about 1 cm or more, and indusial segments few, wide, entire, and with few projections. The diploid form is rare, most plants being tetraploids. Whether they are allo- or autotetraploids is unknown. Woodsia plummerae crosses with W. phillipsii to form sterile intermediates.A
