Botany Photo of the Day
In science, beauty. In beauty, science. Daily.

February 16, 2016: Botany Photo of the Day will return this spring with a new format similar to the new UBC Botanical Garden web site. In the meantime, please enjoy the restored content!

Disanthus cercidifolius

Disanthus cercidifolius

The specific epithet for redbud hazel, cercidifolius, implies that the “leaves are of Cercis”; the resemblance is such that a quick glance at the shrub can lead to misidentification during certain times of the year. However, when the chlorophyll in the leaves of Disanthus cercidifolius begins to break down, a panoply of colours are revealed dissimilar to the autumn colours of Cercis.

The genus Disanthus is monotypic, meaning it contains only one species (compare with a monotypic family – it would only contain one genus, like the Nepenthaceae). Similarly, it is recognized that Disanthus has no close relatives within the witch-hazel family, relatively speaking. For more on its phylogenetic relationships, see: Li et al. 1999. Phylogenetic relationships of the Hamamelidaceae inferred from sequences of internal transcribed spacers (ITS) of nuclear ribosomal DNA. Am. J. Bot. 86:1027-1037.

The USDA link has a bad href; you've got 'title= in the url.

And thanks for the wonderful site. It always makes me want to learn more about plants.

Thanks, Arteth, fixed. Had a ' instead of a ". And you're welcome.

I don't know when BPOD was added to, because I've been relying on refdesk since it was established. But I am SO GLAD it was! Your site is one of the best for the English-speaking inhabitants of this planet. It makes me wish I had studied botany formally. Your site is surely the next best thing.

Thanks Kris for the kind comment.
