Volunteer Pine

Pinus species

Pinaceae family.

For full descriptions see Pine; Pinaster or Pine; Radiata under the crop menu.


Pines are tall evergreen trees to 40 m high with rough and ridged brown bark and whorls of branches. The leaves are needle-like, in groups arising from the axils of basal scale leaves, the needle-like leaves and scale leaves falling together as a unit. The inflorescence is of separate male and female cones, both on the same tree. The male cones are small and spike-like with numerous tiny bracts each having 2 pollen sacs. The female cones are larger with numerous larger bracts each with 2 ovules. The fruiting cones are large and woody, more or less egg shaped and 70-250 mm long, they take 1-2 years to mature and eventually open to release the small winged seeds.


Aleppo Pine (Pinus halepensis)
Canary Island Pine (Pinus canariensis)
Caribbean Pine (Pinus caribaea)
Loblolly Pine (Pinus taeda)
Maritime Pine (Pinus pinaster) has needle-like leaves in pairs, 50-300 mm long, the young shoots yellowish brown and is to southern Europe.
Monterey Pine (Pinus radiata) has needle-like leaves in threes, 80-150 mm long, the young shoots greenish and is native to California.
Patula Pine (Pinus patula)
Ponderosa Pine (Pinus ponderosa)
Stone Pine (Pinus pinea)
Slash Pine (Pinus elliottii)

Maritime and Monterey Pine are widely planted for timber and are now naturalised along roadsides and in bushland near plantations and near old settlements. Pollen is shed in spring.

Plants of similar appearance:

Possibly confused with Callitris (Rottnest Island Pine), but Callitris is a smaller tree to 6 m high, its leaves only obvious in young shoots as they become fused to the stem with age leaving only small scale-like tips free. The cones are also smaller, 25-35 mm long and globular.
