E. regnans F.Muell. Messmate stringybark, mountain ash and alpine ash respectively. Alpine ash attains heights of 20 to 40 m, occasionally 90 m, with stem diameters of 2 to 3 m, and messmate 45 to 90 m and 2 to 3 m diameter. Heartwood is light brown, yellow-brown or straw coloured to brown or pink brown. Sapwood is 2 to 3 cm wide, pale and not clearly distinguishable from heartwood in alpine and mountain ash, and pale yellow and usually distinguishable from heartwood in messmate stringybark.
Texture is coarse and open, with straight grain and prominent growth rings.
To reduce surface checking, boards are usually quartersawn. Relatively easy to work, dresses and finishes well, and polishes and stains easily. Sapwood of messmate stringybark is susceptible to Lyctus borer attack. Used for pulp, paper and hardboard.
