Catching up with yesterday's #januarty prompt, #plant, with a couple of images from Botanica Mathematica. In 2013, Julia Collins and I started this community participation #mathscraft project with #binarybonsai knitted or crocheted trees. We collected and classified around 80 specimens over 4 years.
