It is usually a small tree, although under favorable conditions it 
reaches a diameter of 4-7 em. (16-28 inches) and a height of 25 m. 
(80 feet). In cutting quite a number of mature trees on the Forest 
Reserve it was found that many of the larger trees were doty at 
the base. 
The published records of the distribution are as follows: Clark 
(Baird and Taylor) and (Smith). 
Additional records are: Clark (Deam). 
Economic uses. Wood light, soft, not strong, brittle and light 
brown. Used in construction and for fuel. Supply so limited as 
to be of little economic importance. It grows rapidly, and since it 
is adapted to the sterile hillsides it might be successfully used in. 
reforesting ercded hillsides. 
2. LARIX. Tue Larcues. 
Larix laricina (Du Roi) Koch. Tamarack. Larcu. Plate 10. 
Trees very tall; bark gray or reddish brown, furrowed and scaly; 
branches remote, usually horizontal; leaves pale green, triangular 
in cross section, 1-2.5 em. (%¢-1 inch) long, obtuse at the apex, in 
clusters on the branches, or scattered along the season’s shoots, 
falling off in the autumn; staminate flowers borne on the short 
and leafless lateral branches, the pistillate appear with the leaves 
on the branches of a previous season; cones borne on the short and 
stout dwart branchlets, erect or nearly so, 12-20 mm. (3%-”% inch) 
long, reddish-brown while growing, turning to a light brown at 
maturity, persisting on the tree for at least a year. 
Distribution. From Labrador south to northern Pennsylvania 
and Indiana, west to the Rocky Mountains and north to Alaska. 
In Indiana it is confined to the northern part of the State where 
it is found in cold swamps or in peat bogs where it frequently forms 
dense stands. It flourishes in situations too low for other species 
of trees. It is frequently associated with the birches (Betula lutea 
and pumila), poison sumac (Rhus Vernix), black alder (Ilex verti- 
cillata) and swamp blueberry (Vaccinium corymbosum). It ex- 
tends south in the state to 41° of latitude. In our area it seldom 
acquires a diameter over 5 dm. (20 inches). Locally it is classed 
as white and yellow tamarack. The yellow is considered the better 
of the two. 
The published records of the distribi.tion are as follows: Kos- 
ciusko (Chipman), (Clark), (Scott) and (Youse); Marshall (Hess- 
ler); Noble (J. M. Coulter) and (Van Gorder); Steuben (Bradner). 
Additional records are: Dekalb, Porter and Steuben (Deam).
