Examples
The contrast between the springwood and summerwood is not strong.
The springwood is filled with large pores, the summerwood with smaller ones.
There are many pores, however, and those in the springwood are arranged in bands.
Sometimes, and with certain species, the springwood is much broader than the other.
It is porous, but the pores are small, except one or two rows in the springwood.
