Some moss sporophytes have teeth. Some have two rows of teeth!

The conifer _Podocarpoxylon mazzonii_ from the uppermost Cretaceous of Patagonia, in three sections: radial longitudinal, tangential longitudinal, and transverse.

Yes, it has multiseriate (up to pentaseriate) rays.

Clusia major (Trinidad & Lesser Antilles) has dangling aerial roots that eventually touch the earth—not surprising for a hemiepiphyte that starts life in a tree (or, as here, on a cliff). What is surprising is that sometimes shoots grow from the roots. #Clusiaceae #TropicalBotany #Botany 🌾🧪🌱

You know what's cool too ? Plants ! We had 3 of them this year : the cretaceous conifer Sequoites🌲, a really close relative of our modern seed plants called Runcaria🌾, and Asterophyllites, which is the given name of the leaves from carboniferous tree-size horsetails like Calamites🌿
From top to bottom : Branches and cones of Sequoites, a cretaceous conifer closely related to cypress family (Cupressaceae) Asterophyllites equisetiformis, aka leaves of the lycopod relative Calamites, a tree-size plant that live during the Carboniferous in what's now Europe.

🍎 C’est la saison des pommes !
Saviez-vous que pour les botanistes, ce fruit emblématique… n’est pas vraiment un fruit ?

En effet, la partie correspondant à ce qui était l’ovaire de la fleur se limite en réalité au trognon.
Ce que nous mangeons est en fait un dérivé du réceptacle floral.
Photo de deux pommes vertes. Une est entière et l'autre coupée en deux, ce qui permet de voir sa structure interne, la partie charnue et le trognon qui contient des loges où se trouvent les pépins. Photo par Mónika Erdei, via Pexels.com

🌳 New paper out in Ecology Letters! 🌱
Our latest study, led by Lukas Magee, shows that the “legacies” of trees continue to shape forests long after they die.

Holoparasites are those plants that take water (+ minerals) AND sugars from their hosts. These plants lack both roots and chlorophyll, so they are wholly dependent on their hosts. This is the magnificent Lathraea clandestina. #parasite #Orobanchaceae #Botany 🌾🧪🌱
