I’m on vacation, so only a short written accompaniment today. – Daniel
The Herbarium at the Rancho Santa Ana Botanic Garden has an excellent article on Dryopteris cycadina, or shaggy wood-fern.

Dryopteris cycadina – Z6 – RHS Index of Garden Plants, Griffiths
Pojar & McKinnon list three dryopteris native to NW coast – D. expansa (shield fern), D. filix-mas (male fern) and D. arguta (coastal wood fern).
The shown plant is not Dryopteris cycadina – it is not even a member of the Section Hirtipedes at all. D. cycadina has black scales and pinnae, wich are very little lobed (almost entire), never entirely pinnate.
Ralk – any suggestions on what it might be? We’d sure like to get the plants in the collection labelled correctly.
This is not a Dryopteris, but an Polystichum?!
Looks like Polystichum polyblepharum. I suspect the labels were close together.
So, the confusion seems to be arising from there being multiple accessions of ferns overlapping in the same space, and possibly photographing one and writing down the label of the other. I’ve just looked at the fronds from what is labeled as Dryopteris cycadina, and it clearly isn’t a Polystichum — but it also doesn’t look like Dryopteris cycadina. Douglas, Eric, and I will look at this closely in the next couple weeks, I should think.
