==Description== [[File:Cedrus libani shoot.jpg|thumb|Foliage]] ''Cedrus libani'' can reach {{Convert|40|m|ft|abbr=on}} in height, with a massive [[monopodial]] columnar [[Trunk (botany)|trunk]] up to {{Convert|2.5|m|ftin|abbr=on}} in diameter.<ref name=":0">Farjon 2010, p. 258</ref> The trunks of old, open-grown trees often [[Tree fork|fork]] into several large, erect branches.<ref name=":1">Masri 1995</ref> The rough and scaly bark is dark grey to blackish brown, and is run through by deep, horizontal fissures that peel in small chips. The first-order branches are ascending in young trees; they grow to a massive size and take on a horizontal, wide-spreading disposition. Second-order branches are dense and grow in a horizontal plane. The crown is conical when young, becoming broadly tabular with age with fairly level branches; trees growing in dense forests maintain more conical shape.<ref name=":0"/> ===Shoots and leaves=== The [[Shoot (botany)#Shoot types of woody plants|shoots]] are dimorphic, with both long and short shoots. New shoots are pale brown, older shoots turn grey, grooved and scaly. ''C. libani'' has slightly resinous ovoid [[Bud|vegetative buds]] measuring {{Convert|2|to|3|mm|abbr=on}} long and {{Convert|1.5|to|2|mm|abbr=on}} wide enclosed by pale brown [[deciduous]] scales. The [[leaf|leaves]] are [[Acicular (botany)|needle-like]], arranged in spirals and concentrated at the proximal end of the long shoots, and in clusters of 15β35 on the short shoots; they are {{Convert|5|to|35|mm|abbr=on}} long and {{Convert|1|to|1.5|mm|abbr=on}} wide, [[Rhombus|rhombic]] in cross-section, and vary from light green to glaucous green with [[stomata]]l bands on all four sides.<ref name=":0"/><ref name=":6">Hemery & Simblet 2014, p. 53</ref> ===Cones=== ''Cedrus libani'' produces cones beginning at around the age of 20β40. Its cones are borne in autumn, the male cones appear in early September and the female ones in late September.<ref name="CABI">CABI 2013, p. 116</ref><ref name=":6"/> Male cones occur at the ends of the short shoots; they are solitary and erect about {{Convert|4|to|5|cm|abbr=on}} long and mature from pale green to pale yellow-brown. The female seed cones also grow at the terminal ends of short shoots. The young seed cones are resinous, [[Sessility (botany)|sessile]], and pale green; they require 12 months after pollination to mature. The mature, woody cones are {{Convert|8|to|12|cm|abbr=on}} long and {{Convert|3|to|6|cm|abbr=on}} wide; they are scaly, resinous, ovoid or barrel-shaped, and green ripening to grey-brown the autumn after pollination. Mature cones open from top to bottom, they disintegrate and lose their seed scales, releasing the seeds until only the cone [[rachis]] remains attached to the branches.<ref name=":1"/><ref name=":6"/><ref name="CABI"/><ref name=":01">Farjon 2010, p. 259</ref> The seed scales are thin, broad, and [[coriaceous]], measuring {{Convert|3.5|to|4|cm|abbr=on}} long and {{Convert|3|to|3.5|cm|abbr=on}} wide. The seeds are ovoid, {{Convert|10|to|14|mm|lk=|abbr=on}} long and {{Convert|4|to|6|mm|abbr=on}} wide, attached to a light brown wedge-shaped wing that is {{Convert|20|to|30|mm|abbr=on}} long and {{Convert|15|to|18|mm|abbr=on}} wide.<ref name=":01"/> ''C. libani'' grows rapidly until the age of 45 to 50 years; growth becomes extremely slow after the age of 70.<ref name="CABI"/>
