'''''Pinus devoniana''''' (synonym '''Pinus michoacana''') is a species of conifer in the family Pinaceae. It is found in more than 15 states of Mexico - from S. Sinaloa to Chiapas - and Guatemala in montane, relatively open pine or pine-oak forests at altitudes from {{cvt|900|to|2,500|m}}.<ref name=far1>Farjon et al. 1997, p. 58, Farjon 2001, p. 175</ref>

''Pinus devoniana'', which is locally called "pino blanco", "pino lacio" or "pino prieto", is a tree of medium size, which can grow {{cvt|20|–|30|m}} tall, with a dbh to {{cvt|80|–|100|cm}}. It has curved foliage twigs and very long needles, typically from {{cvt|25|–|40|cm}}, though Mirov cites needles up to {{cvt|50|cm}} long,<ref>{{cite book | last= Mirov | first= N.T. | date= 1967| title= The Genus Pinus | location= New York | publisher= Roland Press |page= 372 }}</ref> in fascicles of 5. The cones, which grow solitary or in whorls of 2-4 on thick, short peduncles, leaving a few scales on the branch when falling, are usually large and often curved, {{cvt|15|–|35|cm}} long and {{cvt|8|–|15|cm}} wide when open.<ref name=far2>Farjon et al. 1997, p. 58, Farjon and Styles 1997, p. 137</ref>

''Pinus devoniana'' is closely related to ''Pinus montezumae'' (the Montezuma pine).<ref name=kentea>Kent 1900, p. 345, Dallimore and Jackson 1954, p. 504 and Farjon 1984, p. 115 treat ''P. devoniana'' as a synonym of ''P. montezumae''</ref> These species are sometimes difficult to distinguish, while hybrids probably occur. The cones are especially variable. Overall, both foliage and cones are larger in ''Pinus devoniana''.<ref name=far3>Farjon et al. Kew 1997, p. 58</ref>
