 second pairs of leaves of the axillary bud (pseiulostipules). Inflorescence 

 a panicle or raceme (simple or with cymose ultimate branching), terminal

 American. 



For the sake of convenience the " length " of the seed is here taken as its longest

 of the seed arc the sides facing the top and bottom of the capsule.
