Down in sheltered lake hollows, on beds of rich alluvium, it varies so far from the common form as frequently to be taken for a distinct species.

在有遮蔽的湖洼中，在丰富的冲积层上，它与常见的形态相差甚远，以至于经常被认为是一个独特的物种。

At an elevation of about 9000 feet above sea-level they seem to have arrived at middle age, -that is, their basins seem to be about half filled with alluvium.

在海拔约 9000 英尺的地方，他们似乎已经到了中年，也就是说，他们的盆地似乎大约有一半是冲积层。

It grows heartily everywhere-on moraines, rocky ledges, along watercourses, and in the deep, moist alluvium of meadows, with a multitude of seedlings and saplings crowding up around the aged, seemingly abundantly able to maintain the forest in prime vigor.

它无处不在——在冰碛、岩石壁架、河道沿岸，以及草地深处湿润的冲积层中，大量的幼苗和树苗簇拥在老龄化的周围，似乎足以使森林保持生机勃勃。
