Close-up photo of three large brown seeds, one cut in longitudinal section to reveal laminar ruminations throughout the endosperm. A ruler shows the seeds are nearly 2.5 cm long. Photo by Scott Zona CC BY-NC 2.0.

An endosperm is described as ruminate when it is penetrated by the seed coat. The nature of the ruminations varies somewhat across the plant kingdom. Sometimes the ruminations are plate-like or laminar, as in Asimina triloba. #Annonaceae #seed #endosperm #ruminate #Botany 🌾🧪🌱

Most flowers have their perianth parts arranged in whorls, i.e., an outer whorl of sepals surrounding 1 or more inner whorls of petals. In this Asimina reticulata, the two whorls of petals are dissimilar & readily distinguished. The sepal whorl isn't visible in the photo. #Annonaceae #Botany 🌾🧪🌱

Yes, even Roman emperors cared about naming things. 🏛️ Marcus Aurelius said: “Tell yourself its proper name.”
Wise advice for rare plants! 🌱 Two little-known species of #Annonaceae from Peru now formally described by @larschatrou.bsky.social, @luizhhziul.bsky.social et al.: doi.org/10.3897/phyt...

The development of the embryo and ruminate endosperm in an early-divergent angiosperm, Asimina triloba (Annonaceae) AbstractBackground and Aims. Embryo and seed development are essential for the reproductive success of flowering plants. However, these processes remain un

Why does this matter?
Understanding how these unique seeds develop can reveal how different reproductive strategies evolved in flowering plants and help preserve biodiversity in early-divergent lineages like Annonaceae. 🌿📚(10/10)

Green, pendulous bud covered in thick layer of reddish-brown hairs that extends onto peduncle.

Way down yonder in the pawpaw patch, buds are getting ready to open. Soon to be covered with flies and beetles. #botany #annonaceae #pawpaw

A quick visit to the Paris #Herbarium. Sampling #Annonaceae specimens, doing some good old taxonomy and using Near Infra Red Scanning NIRs on leaves to test if we can use that to ID species. Flower of #Fenerivia oligosperma, endemic to #Madagascar. @mnhn.fr @ird-fr.bsky.social

A red fruit still on the tree. It is red but it becomes a darker red when ripe like a burgundy purplish red. The fruit resembles a dragon egg with spiky ends. It is considered a rare tropical fruit and some of the species in its family are threatened and on the endangered list.

Here’s the only dragon egg that survived the season. Will leave it to ripen on the tree for a few more days, hopefully that’s enough time to become sweeter since this specific hybrid tends to be on the bland side tasting just like unsweetened coconut yogurt.

Behold! First Dragon Egg (Red Atemoya hybrid) of the season just dropped. Like, literally, it dropped off the tree right as I walked into the greenhouse.😆
