Graduate student Donna Ford, working under the supervision                 of Dr. Peter Raven, will conduct a taxonomic study of 20 or so                  species of annual plants of the genus Calandrinia of the purslane               family Portulacaceae in Chile.  Data will be obtained from new                  field collections made in Chile and from herbarium collections,                 with additional greenhouse and laboratory study of morphology,                  anatomy, chromosome numbers, pollen, and flavonoids.  The                       distribution of character variation within and among populations                of these plants will be examined, considering the roles of                      biogeography, ecology, and reproductive biology.  Computer                      programs for deriving evolutionary patterns will be used to                     determine species relationships and to test hypotheses about                    modes of speciation and routes of migration.  This project will                 provide valuable knowledge about the systematics and population                 biology of semi-arid zone plants and contribute information                     useful for the biotic inventory of South American plant                         resources.
