Photo of a head of small, white, star-shaped flowers with exserted stigmas.

I end the week with a final Asterales photo. It's a gorgeous shot of Boopis anthemoides by Anibal Prina CCBYNC4 via
iNaturalist. Yes, the genus name is Boopis. It's fun to say. 🤭#Asterales #Calyceraceae #lesserknownAsterales #Botany #PlantScience 🌾🧪

Photo of a rosette plant growing among pebbles. A large scape with a dense head of flowers is subtended by secondary scapes and smaller heads.

Photo of a rosette plant with a sessile head of flowers in the center of the rosette.

A couple more photos (from iNaturalist) of Calyceraceae just because they are so awesome!

Plate of two photos. 1st shows the habit of a small, compact plant with long scapes and spinose heads. 2nd photo is a close-up of the head with long spinose sepals.

#Calyceraceae are sister to Asteraceae but restricted to southern South America. They are super cool with flowers in heads, sepals are sometimes spinose, outer layer of the tubular corolla is photosynthetic, stigmas are clavate. 📷: Calycera herbacea, Bruno Alzugaray CCBYNC4 #Botany #PlantScience 🌾🧪
