Flattening Out

I relocated some plants - mainly to group together plants with similar watering requirements. This also gave me an opportunity to take a closer look at the plants while I was moving them. The Pachypodium brevicaule showed some changes - notably the caudex seems to be flattening out.

 

 I'm not sure if this is a response to too much water (potential rot), or just the plant continuing to develop (preparing to spread out horizontally). It looks healthy and doesn't have any sunken spots that would indicate rot, so I'm going to go with the prospect that it is preparing to grow out horizontally.
