Excited to present this description of a new Encelia from Baja California Sur. A beautiful bloomer and rare species with only a handful of documented populations along a rugged coastline.

More exceptional #endemics. This time Sonchus (Asteraceae)
I think... Sonchus acaulis (cerrajon) and Sonchus congestus (cerraja).

One of our scientists, Jennifer Ackerfield, described a thistle that is new to science. This is the first newly described living organism of 2022 in the Rocky Mountain Region! Thanks @davidgilbert4u @ColoradoSun coloradosun.com/2022/02/15/f…

Possibly the least Asteraceae-like #Asteraceae plant ever. Incense Plant (#Calomeria amaranthoides), native to eastern NSW and VIC, thrives after bushfire, only lives for several years. The foliage is aromatic as well.

A sweet reminder from the dictionary: the word ‘daisy’ was originally ‘day’s eye’, because the flower opens its petals at dawn to reveal its sunny central disc, and closes them again at dusk.

As to what disc and ray florets are in the Asteraceae, try this diagram. 'Flowers' are made from two types of tiny #flowers crowded together, either all one type (like #thistle - disc florets or #dandelion - ray florets) or a mixture, like yarrow. Detail gets complicated!

C'est ne pas un cactus! In @cobotanist's new paper out in Capitulum, molecular, morphological, and ecological data support the recognition of five new thistles from the alpine tundra of the rocky mountains, including Cirsium funkae: fagro.edu.uy/~bioveg/capitul…

Sunflowers have distinct UV patterns to draw in pollinators called nectar guides. It now appears that the same compounds making these patterns might help the plants retain water in a drought. elifesciences.org/articles/7…
