Abies religiosa
''Abies religiosa'', sacred fir or in Nahuatl, ''oyamel'' is a fir native to the mountains of central and southern Mexico (Eje Volcánico Transversal, Sierra Madre del Sur) and western Guatemala. It grows at high altitudes of in cloud forest with high rainfall and cool, humid summers and dry winters in most of its habitat regime but in the state of Veracruz to the east it grows with precipitation all year long. Regular winter snowfalls occur on the highest populations.
==Description==
''Abies religiosa'' is a medium-sized to large evergreen coniferous tree growing to tall with a trunk diameter of up to . The leaves are needle-like, flattened, long and wide by thick, dark green above, and with two blue-white bands of stomata below; the leaf apex is acute. 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 reddish-brown, hairless or with scattered pubescence. The cones are long and broad, dark blue-purple before maturity; the scale bracts are purple or greenish, of moderate length, with the tips exposed in the closed cone. The winged seeds are released when the cones disintegrate at maturity about 7–9 months after pollination. Trees from the western end of the range on Nevado de Colima, Jalisco have cones with larger, reflexed bract scales (similar to noble fir cones); these are sometimes treated as a separate species, ''Abies colimensis''.
