There are at least 42 species from 25 genera that have the word timbo as all or part of one or more of their common names and I have no idea which of them are represented on this page except as specifically listed. There is another wood called timborana that might well be confused with this one.
my samples: NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K) colors will vary under other lighting conditions
both sides of a sample plank of timbo / Enterolobium contortisiliquum --- HUGE enlargements are present. This sample was loaned to me by David Clark whom I thank for this and other contributions to the site. The unlabeled side is a more uniform color because it is sanded down to 240 grit whereas the labeled side is raw and has a slightly mottled patina.
