Polystichum brauniiHavainnoija

These are photos of the same fern I posted from 10.04.24 this year. I labeled it Braun’s, but someone suggested it is the hybrid Polystichum x potteri. The photos from this year are not representative of the plant, but these from 10.10.23 are. Maybe it is the hybrid since there seems to be some possible auricles on inside pinnules. I will let you experts decide!

We have been monitoring this site for a long time and were shocked to see this fern in such poor condition this year. Last year it was large & robust. Large fronds from last year still there, and we could also see 3-4 undeveloped fiddleheads. Wondering if the late Spring cold snap/freeze affected it this year?

Unsure on this one, but my impression in the field was definitely P. braunii over setigerum. Photos like #7 look perfect for braunii to me, but other fronds look to have less stalked pinnules (and some enlarged pinnules at the base) which leaves me with a little doubt. Shown on the left in the last photo, and in direct comparison to the neighbouring plant (https://www.inaturalist.org/observations/136882666) in the second-to-last photo (this plant in the hand, other plant in two fronds behind).

A new species for me if confirmed. Rather similar to P. andersonii in general, but without any sign of bulblets despite being a large & mature plant, and it being late in the season. All andersonii in the area, even small plants, had reliable bulblets present on all fronds.
Lower pinnules on the larger pinnae are distinctly stalked, while the rest are attached by a wide base. Certainly very different than P. braunii.

Might be a P. cali in this mix on the Sanborn Trail. A great place for ferns!

Die Zikade singt auf einem Baum an der Wetzelsdorfer Straße in Graz. Ich hörte sie auch an den drei folgenden Tagen an der gleichen Stelle, jeweils am späteren Nachmittag bei über 30 °C. Gesehen habe ich sie nicht.

Growing in a clearing near the forest, on rocky soil.
It's the only exemplary I was able to find, seems rare.

🇨🇿 Věděl jsem, že se s touto kapradinou v údolí Kamenice setkám a rostla opravdu na mnoha místech ale tohle místo, pod zříceninou hradu Návarov, mi zcela vyrazilo dech. Desítky mohutných rostlin.
🇬🇧 I had known I'd find this fern in the Kamenice river valley and it indeed grew in many many places but this one, under the Navarov castle ruin, took my breath away. Dozens of large plants.
