It's happening.

La moitié des réactions à cet article qui interviewe 3 scientifiques à propos du réchauffement des océans et ses conséquences sont des "😂". On est pas bien, là, dans le déni ?

Connaissez vous les orobranches ? Fleurs de la familles des lamiales (comme la menthe), elles sont caractérisées par l'absence de chlorophylle 1/5

This rough dissection of a Silene banksia fruit shows a single locule (chamber) with the immature seeds on a free-central placenta. The placenta is a central stalk that does not reach the top of the locule, hence “free.” #placentation#Caryophyllaceae#Botany#PlantScience 🌾🧪

Photo of an unripe capsule in longitudinal section. The ovules are attached to a column that rises up in the center of the locule but does not connect with the top of the locule.

This photo of tomato fruit shows a fruit with three carpels forming three locules (chambers). A large, intruding placenta (with its seeds) is clearly visible in each locule. This is axile placentation. #placentation#Solanaceae#Botany#PlantScience 🌾🧪

Photo of a tomato cut in cross-section and back-lit. The tomato has three locules. Three massive placentae are attached in the axillary position of the three septa. The seeds are visible attached to the placentae.

Axile placentation is very common in the plant kingdom (maybe the most common among multicarpellate families?). The placentae & ovules (→seeds) are in the axils of each carpel, as seen here in the immature tricarpellate fruits of Iris tectorum. #Iridaceae#placentation#Botany#PlantScience 🌾🧪

Photo of two green (unripe) capsules of Iris. One is cut in cross-section. The capsule is divided into three locules by septa. The unripe seeds are attached to placentae in the axils of the three septa.

Je viens de finir ce livre, que je recommande vivement à toute personne intéressée par l'histoire naturelle. C'est un fabuleux voyage qui remonte le temps, du Pléistocène au Précambrien.

Livre "Otherlands" de Thomas Halliday avec une fougère sur la couverture.
