I've been a bit tardy about posting a follow-up to this image of University of California Botanical Garden at Berkeley by John Davidson. This was taken last month when I briefly visited the garden on my way home from points further south.

Dr. Paul Licht, Director of UC Botanical Garden at Berkeley, was kind enough to take some time out of his day to point out the approximate location of the original photograph. I tried my best to capture a similar image, but things have changed quite a bit -- for one, I think the place where the original photograph was taken from is now part of a garden bed (and, respecting the rules of the garden, I didn't hop into the bed). What hasn't changed, though, is the columnar cactus on the right-hand side of the image. Labeled Echinopsis pascana (perhaps now considered a synonym of Echinopsis atacamensis subsp. pascana), this particular plant is present in John Davidson's image as well. It's a 1932 accession. For details about the changes in the photograph (including what happened to this particular cactus), see Dr. Licht's comment on the previous entry.
