Maries' fir (Abies mariesii, in Japanese, オオシラビソ or アオモリトドマツ, Oh-shirabiso, or Aomori-todomatsu) is a fir native to the mountains of central and northern Honshū, Japan. It grows at altitudes of 750–1,900 m in northern Honshū, and 1,800–2,900 m in central Honshū, always in temperate rain forest with high rainfall and cool, humid summers, and very heavy winter snowfall.
It is a medium-sized evergreen coniferous tree growing to 15–30 m tall with a trunk diameter of up to 0.8 m, smaller and sometimes shrubby at tree line. The leaves are needle-like, flattened, 1.5–2.5 cm long and 2 mm wide by 0.5 mm thick, matt dark green above, and with two white bands of stomata below, and slightly notched at the tip. The leaf arrangement is spiral on the shoot, but with each leaf variably twisted at the base so they lie flat to either side of and above the shoot, with none below the shoot. The shoots are orange-red with dense velvety pubescence. The cones are 5–11 cm long and 3–4 cm broad, dark purple-blue before maturity; the scale bracts are short, and hidden in the closed cone. The winged seeds are released when the cones disintegrate at maturity about 6–7 months after pollination.
Maries' fir is very closely related to Pacific silver fir A. amabilis from the Pacific coast of North America, which is distinguished by its slightly longer leaves (2–4.5 cm) and larger cones (9–17 cm long).
Maries' fir is named after the English plant collector Charles Maries (1851–1902), who introduced the species to Britain in 1879.
