The cones of larches mature in a single season, and often hang on the trees several years. They are conspicuous in winter when the branches are bare of foliage. The adhering cones are generally seedless after the first season, since they quickly let their winged seeds go. The male and female flowers are produced singly on branches of the previous year.
The eastern and northern larch (_Larix laricina_) has a number of names. It is commonly known as tamarack in the New England states and in New York, New Jersey, Pennsylvania, Indiana, Illinois, Wisconsin, Michigan, Minnesota, Ohio, and in Canada. The name larch is applied in practically all the regions where it grows, but it is not used as frequently as tamarack. Hackmatack, which was the Indian name for the tree in part of its eastern range, is still in use in Maine, New Hampshire, Massachusetts, Rhode Island, Delaware, Illinois, Minnesota, and Ontario. Nurserymen call it American larch to distinguish it from other larches on the market, particularly the European larch. Michaux, an early French botanist who explored American forests, called it American larch (_Larix americana_), and the name which he gave has been retained by many scientists to this day. In the Canadian provinces north of the Great Lakes, and also in Maine and New Brunswick, it is frequently called juniper, but without good reason, for it has little of the appearance and few of the qualities of the junipers. In some localities it is called black larch, and in others red larch. The first name refers to the color of its bark, the last to the leaves when about to fall, for they then change to a brown or reddish color. They fall in the autumn, and the branches are bare until the next spring. Some of the New York Indians observed that peculiarity of the tree which they thought should be an evergreen like the balsam and pines with which it was often associated, and they named it kenehtens, meaning “the leaves fall”. Indians did not, as a rule, give separate names to tree species, and when they did so, it was because of food value, or from some peculiarity which could not fail to attract the notice of a savage.
The tamarack’s geographical range is remarkable. It is said to be best developed in the region east of Manitoba, but it extends southward into West Virginia and northward to the land of the midnight sun. It maintains its place almost to the arctic snows, and the willow is about the only tree that pushes farther north. It is found from Newfoundland and Labrador far down toward the mouth of the Mackenzie river, north of the arctic circle. It grows on dry land as well as wet, but is oftenest found in cold swamps, particularly in the southern part of its range. Silted-up lakes are favorite situations, and on the made-land above old beaver dams.
