UPDATE 31 July 2020 email reply from Todd Rounsaville to Connie Barlow. Todd informed Connie that April 2020 he shifted from Polly Hill to National Arboretum in Washington, D.C., where he is Lead Scientist Woody Landscape Plant Germplasm Repository. He wrote of the Polly Hill site, "... The Torreyas there were doing okay when I left in April; there were some prostrate forms in the shade that I think came from Jack Alexander. The others (3) were upright, about 4 to 5' tall, and I assume these would have been the ones from you, though if my memory serves Jack Johnston may have been listed as the source."
