A common species in most tropical countries. The tropical form of Sesbania aegyptiaca 
is said to have uniformly yellow flowers; a second form described by Persoon as S. picta 
has the standard finely mottled with purple. Whilst we have not considered it worth 
while to distinguish these two conditions, owing to the difficulty of determining them 
from dried specimens, we have maintained the var. bicolor of Wight and Arnot, which 
is probably only found in cultivation, and has the standard petal entirely suffused with 
purple. In Africa, as in parts of India, the mottled form appears by far the most common. 
According to Prain (l.c.), S. aegyptiaca is a very familiar hedge plant in Indian fields 
and gardens. Its wood is still (in India) highly reputed as a source of charcoal for gun- 
powder manufacture.
