Bryum bornholmense - a tuberous Bryum of heathy soils, in this case Odiham Common, N Hants. Tubers are amber coloured in incident light, and translucent with thin cell walls and barely protuberant cells in transmitted light. Has strong leaf margins with border cell walls approx 3 microns.

It’s widely known (and, I think, pretty uncontroversial) that learning requires effort — specifically, if you don’t have to work at getting the knowledge, it won’t stick.
Even if an LLM could be trusted to give you correct information 100% of the time, it would be an inferior method of learning it.

Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other.

While Magnolia relies on biotic seed dispersal, Liriodendron relies on the wind. Each carpel becomes a woody, winged fruit (except for the lowermost carpels, which form a basket to hold their winged sisters). This is L. tulipifera. #dispersal #Magnoliaceae #Botany 🌾🧪🌱
