Here are a couple of plants we saw in Oaxaca. I was mostly taking pictures of other plants, but these are native to there and so they were prominently featured in the bot garden.
Pachypodium in winter mode here ...
Age spots, as it were
Site of the original flowering event
Compare these next two pics... one is a single shot (f/16) aiming at the front-most part of the plant and the other is a composite of 12 shots (also f/16) focusing further and further back ... big difference in apparent depth of field
Using the same method closer up
Here showing the difference between the internodes it arrived with (bottom) and the ones it developed after it got here (top).
