State Board of Forestry. 103 



It is usually a small tree, although under favorable conditions it 

 reaches a diameter of 4-7 cm. (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 eroded hillsides. 



2. LARIX. The Larches. 



Larix laricina (Du Roi) Koch. Tamarack. Larch. 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 cm. (5^-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 dwarf branchlets, erect or nearly so, 12-20 mm. (^-Vg 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 distrib. 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).
