Fabaceae-Caesalpinioideae (Caesalpiniaceae)– Cassia angolensis: Angolan native. This is a rare tree, shown here at Fullerton Arboretum (Fullerton, California, USA). It may well be the only specimen in the USA. It sets pods regularly, but seeds fail to mature properly. I have considered grafting this on the locally-plentiful C. leptophylla.
what are the white flowers on that very lacey looking shrub in the foreground in picture 2?
I believe it’s Cordia parvifolia.
