"Even the strongest and greatest of trees is built up of minute cells, which constitute its stout trunk with its wood and bark, its leaves, flowers, and acorns. All the potentialities of this massive tree were packed into the cells of the acorn."

- Knight and Step 1913, Popular Botany

In a broken, evasive world, reality is what we mean to celebrate, to be partakers of, within this music's sound: look, where the world comes, listen, hear.

Asters and goldenrods, Maple Grove Forest Preserve, yesterday morning. Fight for democracy, science, human decency, and the natural world, and continue celebrating what you are fighting for.

I just noticed this post... Congratulations! I'm psyched to read it.

Andrew Hipp @andrewlhipp.bsky.social · 10d

Fascinating essay by @martinebotany.bsky.social on spiny solanums (tomato et al. relatives) as an example of all the important natural history research left to be done. Great observations on pollination and symbiosis... A very inspiring Sunday morning read!

Earthball (Scleroderma) growing beneath planted bur oaks, The Morton Arboretum. This week my lab group and collaborators are sampling 300 bur oaks out of a 1000-tree experiment planted in 2021 / 2023 and reveling in the soil world as we do so. More to come!

Quercus dentata acorn, Polly Hill Arboretum this a.m.

This is a white oak relative, from a lineage of about 25 spp that made their way from eastern North America to Eurasia ca. 20 million years ago. More closely related to eastern white oak than to East Asian ring-cupped or cork or holly oaks.

American beech (Fagus grandifolia) tip-up, Polly Hill Arboretum. The beeches are succombing to beech leaf disease, caused by nematodes and becoming widespread in the northeast and upper midwest. This is a magnificent forest, but the beeches are heartbreaking.
