I keep seeing posting of new species of ferns, almost on a monthly basis, found in China. It appears to be that there are geographies in China that have had little scientific study.

Certainly looks like Equisetum telmateia var. braunii - Giant Horsetail
15 - 20 species of horsetail world wide. There is only one genus. Equisetum.
Horsetails are 'living fossils' descendants from 300 million years ago giant ferns.
In your learning, I highly recommend, again. It is for the Northeast, but many species are mid Atlantic as well. It is a great introduction. Ferns only, no club mosses or horsetails. Inexpensive, not cheap.

Dr. Alice Gauthey, a Newton International Fellow, standing in a forest, smiling at the camera and holding a leaf. A quote about establishing early-career research independence appears next to her, attributed to her and mentioning The Royal Society: "I wanted to establish greater independence as an early-career researcher. The Newton International Fellowship provided both the time and the resources to develop a strong research portfolio."
The Royal Society's Newton International Fellowships are now open for applications, aimed at non-UK early career scientists who wish to conduct research in the UK. Find out more and apply by 11 March: #RSGrants https://royalsociety.org/grants/newton-international/

@westportastro.bsky.social is open tomorrow night. Jupiter should look nice in their 14" Celestron, possibly in their 25" Obsession, if there's no snow on the ground.
07.01.2026 00:53 โ ๐ 1 ๐ 0 ๐ฌ 0 ๐ 0All the pictures in this thread 1-25 were taken at the Coastal Maine Botanical Garden, Booth Bay, Maine, USA
This is a botantical garden, so many of the ferns are cultivars, not native.
Sensitive fern is a triangular fern. It likes to have its feet wet. Found in low lying areas, marshes and swamps. It gets its name from shriveling at the first cold snap, not because it is delicate. It is roughly triangular shaped. It is a once cut, half twice cut fern, pinnate-pinnatifid.
There is more than just sensitive fern in this picture.
Close up of the fern fronds. They form a grape like structure that winters over and releases their spores in spring. In the winter, with a few inches of snow, the fertile fronds stick up out of the snow letting you know that sensitive ferns grow here. This fertile fronds are different in shape that ostrich ferns, but both winter over and identify themselves in winter.
Sensitive Fern, Onoclea sensibilis
25/25 Fin
Sign - Dryopteris ร remota, Scaly Buckler Fern, Europe Not the best specimen. It is a wood fern. It is a twice-cut, half thrice cut fern, bipinnate-pinnatifid
Scaly Buckler Fern, Dryopteris ร remota
It is a hybrid of Dryopteris affinis, Dryopteris expansa

Royal fern is a tall, waist high and higher, twice cut fern. It is not frilly. It looks almost primitive. The sori are found at the tips of the frond. They have a similar shape to the fertile pinna seen in Interrupted fern. Royal fern does not spread. It creates a large cluster. It likes to have its feet wet. It can be seen growing on tufts out in the middle of a marsh or swamp.
Sign - Osmunda regalis, Royal fern. North America There used to be two varieties of Royal fern. Now these two varieties have been given different specie designation. Osmunda regalis is the European specie of Royal Fern. It tends to be larger. Osmunda specitibilis is the North America specie of Royal Fern.

Common polypody is a once cut fern that grows on calcium rich rocks. It is a small fern. Grows in large colonies.

Common Polypody, Polypodium vulgare

Sign - 'Ghost' Japanese Painted Fern, 'Ghost' Interesting that the specie name is missing. The ferns are green. Japanese painted fern is known for its silver and pink/rose color. See other pictures for this coloring
Sign - 'Red Beauty' Japanese Painted Fern, Athyrium niponicum var. pictum 'Red Beauty' cultivar Japanese Painted Fern is a commonly cultivated fern as it is not the usual green color.
Japanese Painted Fern, Athyrium niponicum var. pictum

Sign - Matteuccia struthiopteris, Ostrich Fern, Circumboreal Found everywhere around the world Fern gets its common name from the sterile frond looking like an ostrich feather. This stand of ostrich fern has shriveled. There are some green fronds. By the time the first snow falls there may be little sign the fern was present, except for the fertile fronds (see other pictures)
The fertile fronds emerge from the center of the vase shape formed by the sterile fronds. The fertile fronds have the ostrich feature shape of the sterile fronds, but a much more compact. They emerge green, turn brown, winter over, and release spores in the spring. Ostrich ferns are easy to identify in the winter, even with a few inches of snow, as the fertile fronds are upright and obvious.
Fertile frond showing the ostrich feather shape.
Ostrich Fern, Matteuccia struthiopteris

Sign - Plumosum Oak Fern, Gymnocarpium dryopteris 'Plumosum' cultivar Not showing good picture of oak fern. It is present, but out of focus.
Oak fern is another that is not once, twice, or thrice cut. It has three lobes, each twice cut. It is similar to bracken fern. Separate lobes are seen in the picture, but a complete easy to see three lobes is missing
A better picture of the three lobes, but not perfect
Another specimen with three lobes, but a damaged specimen
Oak Fern, Gymnocarpium dryopteris

Narrow beech fern is triangular in shape with bottom pinna pair pointing in different direction that the rest of the frond. Narrow beech fern does not have tissue between the bottom and next pair of pinna. Broad beech fern has tissue between the bottom and next pair of pinna.
Single specimen showing the lower pinna pair. This pair is not normal. Both pinna are pointing in the same direction. They should be pointing in opposite directions.
Another specimen. Note the long tapering tip
This specimen shows the pointed lowest pair and tapering tip
Narrow Beech Fern, Phegopteris connectilis
There is a related fern, Broad Beech fern, Phegopteris hexagonoptera
The two ferns are very similar.

Sign - Maidenhair Spleenwort, Asplenium trichomanes, Circumboreal Found everywhere around the world This is a small, delicate fern. It requires specific conditions to thrive.
Sign - Cristata Maidenhair Spleenwort, Asplenium trichomanes, 'Cristata' cultivar The specimen is to the right of the base of the side under the shape of the rock.
Maidenhair Spleenwort, Asplenium trichomanes

Maidenhair fern is another fern that is not one, twice, or thrice cut. It has it own unique shape. The shape is supposed to look like a maiden's hair. This picture is showing some of this colony shriveling for the winter. The entire colony will disappear for winter. The fern likes moist area, preferably misting, like near a water fall.
Maidenhair Fern, Adiantum pedatum

Sign - log fern, Dryopteris celsa, eastern and north-central USA Not clear from the picture which plants are the log fern. The ferns in the picture look like Christmas fern.
