Since my recent observations of this small population of plants have all been in the spring or fall when they don't show the best field marks, I'm adding this older original observation as well.

Descripción

This hybrid occurs here with both parents under an overhanging ledge of a glacial erratic. The erratic is ultramafic peridotite originating from ultramafic outcrops on nearby higher peaks. Both parents are present here in montane forest of Tsuga heterophylla and Abies amabilis, elevation about 1000 meters. The third and fourth photos provide a morphological comparison of the hybrid (in the middle) with both parents. Polystichum kruckebergii, which incorporates the genomes of P. lemmonii and P. lonchitis, is a bodenvag species in regard to ultramafic bedrock. It has apparently acquired its tolerance of ultramafics from its parent P. lemmonii, which is restricted to ultramafic bedrock. This hybrid thus combines the genomes of P. lemmonii, P. lonchitis, and P. munitum. For more details on the analysis of this hybrid see https://www.researchgate.net/profile/Douglas_Soltis/publication/279238216_Electrophoretic_and_Morphological_Confirmation_of_Interspecific_Hybridization_between_Polystichum_kruckebergii_and_P_munitum/links/559ab7cb08ae793d1382129f.pdf

Dryopteris affinis or filix-mas type plant, as previously discussed here:

https://www.inaturalist.org/observations/60128414

Single frond collected today for more detailed photos. I'm happy to take more images of any particular area upon request.

Dark vs light background changes the exposure dramatically in some cases, for example in highlighting the dark marks at the base of the pinna.

I also noted that the leaflets on the lower half of the stem are tilted upwards at close to 45-degrees, hence why they sometimes looked significantly more or less spaced apart in previous photos, depending on the camera angle.

This search for Polystichum on the Evan's Valley Trail was based on John Reynolds' observation from a couple of winters ago: https://www.inaturalist.org/observations/19604739

The majority of the trail is mature second growth evergreen forest, dominated by a ground cover of Western Sword Fern and other common species. Above 400m elevation, the trail enters pockets of older growth forest, and crosses a couple of slide paths from the surrounding steep summits. Just before reaching the major avalanche clearing at the top of the valley at 500m elevation (known for its summer snow caves), the trail reaches an area of old boulders near the stream, with bushy deciduous pockets of Salmonberry & Devil's Club at the edge of the evergreen forest.

In this last 100m of trail, P. braunii was quite common, in these disturbed forest patches. Its habitat preference was quite different from P. munitum, despite growing in close proximity, it did not appear to grow deeper into the forest. Most of the plants of P. braunii were starting to wilt for the season, with the fronds already lying on the ground (although still fully green), likely flattened by an earlier snowfall in November. The leaves were noticeably soft in texture compared to other Polystichum.

Three small plants of P. andersonii were also found in this area. They had noticeably firmer, more evergreen-feeling leaves.


Largest plant seen, over 4' tall when holding the fronds up for photos (but already fallen unfortunately for the season).

Growing with group of P. braunii, but just a little further out from the large boulder so getting a fair bit more light. Bulblets on both large fronds. Long spines.
