The aim of the study was to find out firstly whether there are differences between the etheric oils of botanically alike but in different climatic conditions growing trees, and secondly whether the oils from alike trees are also alike. This article shortly describes the chemical composition of  Pseudotsuga Douglasii cecian Schwerin and Pinus Murrayana Engelm. The needle samples are from Mustiala Arboretum.

The first mentioned contains α-pinene, camphene, bornyl acetate, probably also limonene but no geraniol. Pinus Murraya’s oil contains pinene, camphene, borneol and cadinene.

The PDF contains a summary in Finnish.

Yrjö Ilvessalo. (1929). Notes on some forest (site) types in North America. Acta Forestalia Fennica vol. 34 no. 39 article id 7252. https://doi.org/10.14214/aff.7252

Abstract | View details | Full text in PDF | Author Info

The article includes observations on forest site types in Canada and the United States, with special emphasis on forests of lodgepole pine (Pinus murrayana, now Pinus contorta Douglas ex Loudon) which the author considers a species that can become a favourite exotic tree species in Finland. Some notes are made also about Jack pine (Pinus banksiana Lamb.) and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests. The author was not able to make a systematic forest type investigation, because the journey was made on another purpose. The article describes the vegetation and climate of the visited areas, and divides the forest site types in three groups: Dry forest site types, moist forest site types and grass-herb site types. The vegetation and plant species on several subtypes are described in detail.

The volume 34 of Acta Forestalia Fennica is a jubileum publication of professor Aimo Kaarlo Cajander.
