This is what our right hind wheel looked like on the morning of the second day of our trip (April 6).
Thursday morning revealed that our left hind tyre had a big gash on its side and was letting air out. As luck was, we noticed this in time and got it promptly repaired before leaving Springbok.
The last couple of days have been productive, and we've been processing populations of Lithops marmorata, L. meyeri, and L. geyeri. Below is a shriveled but flowering individual of L. meyeri.
