Larix laricina, commonly known as the tamarack, [3] hackmatack, [3] eastern larch, [3] black larch, [3] red larch, [3] or American larch, [3] is a species of larch native to Canada, from eastern Yukon and Inuvik, Northwest Territories east to Newfoundland, and also south into the upper northeastern United States from Minnesota to Cranesville Swamp, West Virginia; there is also an isolated ...
Taylor (1959) [8] had noted that the most obvious morphological difference between typical Picea glauca and typical P. engelmannii was the cone scale, and Horton (1956,1959) [9] [10] found that the most useful diagnostic features of the two spruces are in the cone; differences occur in the flower, shoot and needle, "but those in the cone are ...
The hybrid Dunkeld larch is widely grown as a timber crop in Northern Europe, valued for its fast growth and disease resistance. Larch on oak was the traditional construction method for Scottish fishing boats in the 19th century. [citation needed] Larch has also been used in herbal medicine; see Bach flower remedies and Arabinogalactan for details.
The main differences between hardwoods and softwoods is that the softwoods completely lack vessels (pores). [1] The main softwood species (pines, spruces, larches, false tsugas) also have resin canals (or ducts) in their structure. [2]

The Pinaceae (/ p ɪ ˈ n eɪ s iː ˌ iː,-s i ˌ aɪ /), or pine family, are conifer trees or shrubs, including many of the well-known conifers of commercial importance such as cedars, firs, hemlocks, piñons, larches, pines and spruces.
The exact temperature which evergreen roots can handle depends on the species, for example, Picea Glauca (White Spruce) roots are killed at −10 °F (−23 °C). [ 7 ] In areas where there is a reason for being deciduous, e.g. a cold season or dry season, evergreen plants are usually an adaptation of low nutrient levels.
These three components are interwoven, and direct covalent linkages exist between the lignin and the hemicellulose. A major focus of the paper industry is the separation of the lignin from the cellulose, from which paper is made. In chemical terms, the difference between hardwood and softwood is reflected in the composition of the constituent ...
