Durango fir

Large, upright-growing, 30 - 40m tall, evergreen, coniferous tree with narrowly pyramidal crown at young age, changing to rounded when more mature. Young trees have smooth, reddish-brown bark, changing to grey. Bark on older trees breaks into oblong plates with dark brown/grey colour. New buds are oblong, 4-5mm long, often cover with resinous layer. Needles are fairly long (1.4 - 4.5cm), rounded at the tip. They are pale blue-green on top with two dull stomata bands underneath, set in two or more ranks on either side of shoot. Cylindrical seed cones are pale yellow-green when young, ripening to brown.
