2. LARIX. The Larches. 



Larix larioina ( Du Roi) Koch. Tamarack. Plate No. 5. 

 Tall spire-like trees, usually 2-3 dm. in diameter, rarel.y as large as 

 5 dm. in diameter; bark gray or reddish-brown, scal.y; twigs slender, 

 smooth, light brown, becoming a dark gray brown; leaves scattered 

 along the shoots of the season, in fascicles on the older branches, usually 

 2()-.50 in a Inmdle; filiform, 1-2.5 cm. long, of^tuso at apex, triangtdar 

 in cross-section, all falling off late in autumn; stammate flowers borne 

 on the short leafless branches, the pistillate ajjpear with the leaves 

 on the f)ranches of the previous season; cones borne on short, stout 

 Ijianchlets, normally erect or inclined to be so, 10-20 mm. long, purplish 

 brown while growing, tinning to a light brown at maturity, persisting 

 on the tree for al:)out a year; wood hartl, heavj', light firown, variable in 

 strength. 



Distribution. — Labrador, Newfoundland south to southern New 

 York, West Virginia, northern Ohio and Indiana, Wisconsin, Minne- 

 sota and northward. In Indiana it is confined to the northern part of 

 the State, and has not been reported south of the northern part of Cass 

 Countj'. The most southern station in the eastern part of the State is 

 about Lake Everett in the northwest part of Allen County. It is found 

 on low borders of lakes, in swamjjs and in bogs. In all of its stations 

 in Indiana it is found growing near the water level in great dejiths of 

 oiganic matter more or less decomposed or in beds of ])eat, which con- 

 tain little or i)ractically no soil. Where it is found, it usually forms a 

 pure stand. 



Remarks. — Formerly the tamarack was a common tree in its area. 

 Recently many of the tamarack swamps have been drained. This 

 with heavy cutting has reduced the supply of tamarack in Indiana to 

 an insignificant amount. The tamarack is popularly classed as white 

 and yellow — the j-ellow being considered the better of the two. In our 

 area it is used principally for poles and posts. There is a diversity of 

 opinion as to the durability of tamarack in contac^t with the soil. The 

 most authentic information places the life of fence posts at about ten 

 years.
