Rattle Beaks

Lyperanthus serratus


Endemic to the southwest of Western Australia. Stalk is about 20cm tall. Quite easy to overlook due to the inconspicuous coloration. The common name derives from the fact that the flowers slightly rattle when gently shaken.


Dry eucalypt forest of Marri and Jarrah.

No species ID suggestions

Thanks for your comments, António, Lauren and Liana! Wildflower season in the south of WA ranks very high on my nature-experiences!

Congratulations on your SOTD Felix! Great spotting. I've been amongst the Marri and Jarrah trees and have clearly overlooked this lovely little plant. Thank you for sharing, and the next time I'm down that way I will try and remember the Rattle Beak. Wicked name :D

Congratulations Felix, your Rattle Beaks is our Spotting of the Day! Still trying to find out what part of the plant rattles...! The white fleshy hairs on the lip?

Very peculiar looking...I have seen rattlepods; the seedpods rattle but this one is mighty strange! Thanks for sharing...otherwise I would never have known this species....

Indeed! I heard it, but I couldn't figure out where it actually rattles.

Very interesting. I wonder what part of the flower rattles? They definitely look like beaks too.
