Bloodroot (Sanguinaria canadensis). Two large, white-petaled flowers with golden stamens growing from the leaf-covered forest floor. Each flower rises on a pink stalk with a single, elaborately-lobed leaf reminiscent of Monstera.

Rue anemone (Thalictrum thalictroides). A single dark pink stalk rises from the leaf-covered forest floor. The stalk has two clusters of three-lobed, paw-shaped leavs and two flowers atop it. The flowers are large and white with golden stamens.

Twinleaf (Jeffersonia diphylla). Two large white-petaled flowers with golden stamens around a large globe-shaped ovary rise from the forest floor, framed between two fallen logs. The flower stalks are pink, and each has a folded, pointed twin pair of leaves attached to it.

These flowers are from 3 families, but they look quite similar. Do any #botanists, #entomologists or forest-floor enthusiasts know if there's some kind of spring ephemeral #pollination syndrome? (1: bloodroot - Papaveraceae; 2: rue anemone - Ranunculaceae 3: twinleaf/jeffersonia - Berberidaceae)

Be more active on here anyway - it's a much nicer environment and there are lots of #botanists, #mycologists, #entomologists etc here (and not on X) who will be interested in your posts.

🎉Thank you to our wonderful community of plant researchers, botanists and plant enthusiasts for helping us reach 5,000 followers.

🌿📚 We look forward to continuing to share exciting plant science with you!

Cell and tissue trait diversity among (A–D) leaves and (E–G) flowers. (A) Average cross-sectional mesophyll porosity (θIAS; mm3 mm-3) for leaves, visualized by averaging across the depth of the microCT scan. Lighter colors indicate more cell material, and darker colors indicate more airspace. (B) 3D volume rendering of the intercellular airspace of leaves. Height (thickness) varies depending on the species. Numbers indicate the porosity (θIAS) of the tissue. (C) 3D volume rendering of one leaf palisade mesophyll cell from a leaf of each species. Numbers indicate the asphericity (⁠⁠) of the cell. (D) 3D volume rendering of one spongy mesophyll cell from a leaf of each species. Numbers indicate the asphericity (⁠⁠) of the cell. (E) 3D volume rendering of one spongy mesophyll cell from a flower of each species. Numbers indicate the asphericity (⁠⁠) of the cell. (F) 3D volume rendering of the intercellular airspace of flowers. Height (thickness) varies depending on the species. Numbers indicate the porosity (θIAS) of the tissue. (G) Average cross-sectional mesophyll porosity (θIAS; mm3 mm−3) for flowers, visualized by averaging across the depth of the microCT scan. Lighter colors indicate more cell material, and darker colors indicate more airspace. Note that in panels (A and G), the width and height are each 600 µm, and the tissue dimensions in panels (B and F) are 600 µm × 600 µm in the paradermal plane with variable height (thickness) depending on the sample. Cells displayed in panels (C–F) are visualized at different scales.

With all the awfulness we wake up to every morning to in America, it is nice that #British and #Irish #botanists keep things in perspective.

The violently pink narrow petals of a Pigface flower with some creamy yellow stamens squeezing through. The flower is a little beat up. In the background the juicy leaves of the plant.

Zooming out, the Carpobrotus flower is seen in a sea of green beefy leaves

Today's big reveal is that the Pigface that never bloomed once in THREE YEARS has popped a flower out. Anyway I'm pretty sure this is pesky Angled Pigface so it may be off for the mulch anyway. Would love an expert to chime in, hello #botanists? #plantID?

An article I collaborated on - "Wikidata for botanists: benefits of collaborating and sharing Linked Open Data" - is in this issue! See academic.oup.com/aob/article/... #Wikidata #Botanists #LinkedOpenData

On today's #WeeklyWalk I saw plenty of new wild hedgerow flowers. Are there any #Botanists out there who can put names to the other 2? The yellow ball flowers are Tansy (Tanacetum vulgare). Definitely more autumnal. Cooler, rain showers & 2 rainbows.

Hahaha... #botanists

Can any #botanists recommend good indoor gardening books for a suburban/city girl who likes plants and isn't a mom (child or pet) so I'm not hung up on are they safe?

We now started the important work of updating the #plant #redlist for #Denmark! This work is done by Nikolaj Sass Ebsen and Peter Wind, two of Denmark's most knowing #botanists. Work is coordinated by us at @au.dk and expected to be finished end 2026-2027. #dknatur #threatenedspecies #iucn

With many petals and lots of flowers per stem, this plant grows 4-5 feet tall with smooth, sword shaped leaves. It’s very invasive and grows by vegetative runners. We’ve been unable to identify it, although it seems to be in the aster family. It’s growing prolifically in my yard in NE Ohio.

BlueSky #Botanists - Can anyone identify this plant? It’s growing in my yard in NE Ohio and is very invasive. It spreads by vegetative runners. The Seek app thinks it’s common sneezeweed but the leaves flower petals do not seem to match. It grows 4-5 feet tall. 🧪

Afternoon!

Deep in the forest section of the property today crazy new fungi emerging - ancient tree clearly decomposing slowly - anyone a #fungi expert and can do a positive id?

It was spectacular and clearly freshly grown.

A dead tree against a background of a blue sky.

#TreeID #Arborealists #Botanists Can anyone identify this tree please? And before any smartarses pipe up, "dead" is not an acceptable answer.

Tree with a thick cluster of branches growing around it from the lowest part of the trunk. Making it look as if there is shrubbery growing around the tree but it's all part of it. The tree is right at the waterline of the canal

Close up of previous photo. Tree with a thick cluster of branches growing around it from the lowest part of the trunk. Making it look as if there is shrubbery growing around the tree but it's all part of it. The tree is right at the waterline of the canal

Do I know any Botanists, gardeners or other plant enthusiasts who know why the trees along the canal grow these thick shrub like branches around their base?
