So like, generally I agree that it’s not polite to stare. But like, P. lambii has A LOT going on, and it takes a good minute to take it all in. Like you might look at it and wonder, why does it have a weird thing that looks like a butthole? What are those gray spots? Or green spots? Or pink spots? Why is it sometimes really round and sometimes really blobby? All great questions, all of which I will do my best to answer. This crustose lichen has a radiating, placodioid thallus (rosette shaped, tile-like toward the center, lobe-like toward the outside). It is grey, cream, or tan, often with a pink or green tinge. The gray or green cracks or pustules you can see are soralia, which produce vegetative propagules in the form of soredia. The weird butthole-shaped, brownish-pinkish blob near the thallus center is a large cephalodia--a section of the thallus containing a secondary, cyanobacterial photobiont in an otherwise algal lichen. P. lambii doesn’t always have cephalodia--they are often only found in specimens that live in particularly moist environments. It also only occasionally produces apothecia, which have a yellow or bubble-gum pink disc and a prominent margin. P. lambii grows on siliceous rock in cold, damp areas near water. It has a scattered and rare distribution in Europe, Africa, South America, Asia, and New Zealand. This fella is easily confused with P. gelida, but they are genetically and chemically distinct. Both can be incredibly variable, so good luck IDing them in the field! At least you will know you are looking at a Placopsis, right? Because no other lichen is quite this same level of odd.

South African botanist Brian du Preez has discovered a beautiful new species from the Iridaceae family high up in the Langeberg Mountains of the Western Cape, South Africa.
The name of the new species, Geissorhiza seracina (common name: Cherry Satin flower), is inspired by the deep cherry-pink color of its petals—with seracus meaning cherry.

Sweet William, Dianthus barbatus
mildly amused by the different strategies plants have chosen to avoid being eaten.
some of them are living out there like, man please dont - dont eat me ok? see im all bitter i dont taste good at all, bro please spit me back out, this isnt funny
and others simply dont have the time for such nonsense and went YOU TAKE... A BITE OUT OF ME?
and sometimes both are the same plant but the thing that eats them is different
