The summerwood is a thin, dark line, separating one annual ring from another.

American Forest Trees |Henry H. Gibson
The annual rings are indistinct, owing to no clear line of separation between springwood and summerwood.

American Forest Trees |Henry H. Gibson
The annual rings are narrow and consist largely of summerwood.
