The record for inactive accession PI 150921 indicates that it was PI'ed in 1945 from seeds collected from the Experiment Station in Winterhaven, Texas, by WT Swingle. References in the US Date & Citrus Station, Indio, accession book refer to seeds collected in Texas by JR Furr, the actual location in Texas not being stated. Olson et al (1961) report 'Sacaton' present at the USDA citrus collection at Rio Farms, Monte Alto. The Rio Farms tree is stated to have been a seedling planted in 1953 originating in Texas. It is therefore probable that 'Sacaton' originated in Texas (Winter Haven Station) and was then planted at Rio Farms and later sent to the Date & Citrus Station. However, 'Sacaton' might be from Arizona. Swingle was in charge of the citrus breeding program (actually all of CPB) during the time period in which Albert Newcomb suggests 'Sacaton' was developed and could have taken seeds from the Sacaton Station to Winter Haven when Sacaton was closed, PI'ing them only after they arrived in Texas. Produces large numbers of seeds containing only nucellar embryos and consequently yields identical F1 seedlings in great numbers.
