Sophora macnabiana (Graham) Skottsb.

Early in the last century a sophora of unknown provenance grew in the Edinburgh Botanic Garden, where it was hardier than S. tetraptera or S. microphylla. It was named Edwardsia macnabiana by Graham in 1838 and portrayed in the Botanical Magazine two years later. Graham suspected that it might be no more than a seedling variation of S. tetraptera, but it seems to have agreed very well with the Chilean form or ally of S. microphylla. It is in cultivation from seeds collected by Comber in the Chilean Andes in 1927.
