Now that I've grown a few different Chiltepin/Tepin varieties and the Florida Wild/Calusa Indian Mound/Grove Pepper I've noticed two different plant forms. I wonder if these are really both Capsicum annuum var. glabriusculum?
This type looks like other C. annuum plants:

This type looks different. Shorter more heart-shaped leaves, the plant doesn't branch as quickly as the first type either.
