2-2 Pinaceae, pine family

Marian C. Munro, Ruth E. Newell, Nicholas M. Hill

Abstract


Most of the pine family are evergreen, our notable exception is larch, whose soft needles turn golden yellow before dropping late fall. Each needle contains a resinous sap, giving a strong odour to the trees. Flowers are unisexual, in the form of catkins (or aments). Catkins are simply aggregations of scales enclosing the stamens or ovules. Pistillate catkins have two ovules at the base of each scale. After pollination, cones or fleshy fruit are formed.Photograph use for this publication are provided by Reg Newell, David Mazerolle, Ross Hall, Martin Thomas, Beth Cameron, Sean Blaney and Megan Crowley.
