of the flower in this series. Sometimes the corolla is reduced to a 
single petal, the standard, as in Amor- 
pha (figs. 166, 167), or is altogether 
absent as in Paryella; sometimes, as 
in Psoralea, the ovary contains but a 
single ovule. We may rarely find 
two or three ovules; and one genus, 
Asagrea, is so far exceptional as to 
possess half a dozen. The androceum 
alone remains as in most Papilionacce ; 
it is decandrous and monadelphous. 
The Psoralee are herbs or shrubs 
whose leaves are covered with glan- 
dular dots. The flowers form racemes
