Stems are reddish brown, lightly lenticeled and have a waxy covering. You can see the swollen base of the petiole, typical for legume family.
Flowers in the spring from spurs. Males and females separate plants but could be on one plant. This is an inflorescence of males. Males have an odd less than desirable smell.
Large spurs on the stems from where the flowers come out each year. Pretty odd looking.
Fruit is a 5-12" long light to dark brown flattened pod containing 10+ flattened seeds. When ripe the seeds are free inside the fruit and rattle when shaken that are glossy. When dried and ground up they are a substitute for cocoa.
The trunks can be really cool with age. This one is downtown Palo Alto.
