Seeds of another palo verde species, Cercidium microphyllum, are attacked by Stator limbatus and Mimosestes amicus in nearly the same way (Siemens et al.
Based on varying patterns of seed predation among species and the increase in pod biomass per seed with fewer seeds per pod, we expected frequencies of multiseeded pods to be much greater for Cercidium microphyllum and Olneya tesota compared to C floridum.
The early collection was necessary because pods of Cercidium microphyllum abscise and drop from canopies in early July, before most M.
As expected, pod biomass per seed in Cercidium microphyllum also increased with fewer seeds in a pod.
Cercidium microphyllum flowers also have the potential to produce many seeds with a mean of 8.
There was no statistically significant difference in the mean number of seeds per pod between Cercidium microphyllum trees at the TMR dry site (1.
deltoidea, triangle-leaf bursage) and Encelia farinosa (brittlebush), with scattered Cercidium microphyllum (follows nomenclature of Hickman, 1993).
Cercidium microphyllum is known to be fire-sensitive with only some minor resprouting (Loftin, 1987; Cave, 1982; Cave and Patten, 1984).

other common shrubs in the area included Larrea tridentata (creosotebush), Cercidium microphyllum
(yellow paloverde), Olneya tesota (ironwood), and Prosopis glandulosa (honey mesquite).
