Collection notes: Collecting this species is time consuming. We also didn’t find or collect enough at the proper time to use in the study. Seeds on this plant mature at different times and drop shortly after they mature. Also, it appears to be a favorite of ants, many of the plants that had mature seed were also covered with ants.
Cleaning notes: Clean seed measurement was basically pure seed but a few still had the calyx attached.
