Five species represented. Two species, _Apodanthera_, and _Chamaecrista
leptadenia_, new to storage records. Several whole fruits of
_Apodanthera_, about 2 inches in diameter, stored in addition to seeds
alone; seeds of this form not previously noted in burrows, but very
abundant in this one, indicating importance of the factor of
accessibility in storage.
