balsam

Soon a dark wall of trees—red spruce, balsam fir, beech, hemlock—surrounds you, and there's a sudden stony persistence.

很快你会被一堵厚厚的树墙包围——红云杉、香脂冷杉、山毛榉和铁杉，这会持续一段时间。

The Christmas season has officially arrived at the White House in the form of a six-meter balsam fir tree.

欢庆圣诞的季节随着一棵6米高的香脂冷杉树的到来已经正式在白宫拉开序幕。
