The plant here figured has long been grown in gardens 
under the name of Psoralea pinnata, itself an old garden 
plant which is stated in the Hortus Kewensis to have been 
in cultivation at Hampton Court so long ago as 1690. 
When Ericas and other South African shrubs were more in 
favour than they are at present, P. pinnata was a favourite 
greenhouse plant, and it is by no means improbable that 
then, as now, the two forms were in cultivation without 
being distinguished from each other. The right of the 
form here figured to separate recognition was pointed out 
by Ecklon and Zeyher more than seventy years ago, and 
although the late Dr. Harvey was led to treat P. pinnata, 
Avuaust, 1910.
