Podocarpus totara - tōtara

Podocarp family: Podocarpaceae

Podocarpus totara is a tall forest tree with brownish green foliage of rigid, linear needle-like leaves and a bark that separates into long narrow strips. Small, fleshy ovule cones are formed in which a green epimatium (an outgrowth of the seed scale) covers the developing seed. After fertilisation the bases of the fertile and sterile bracts fuse and become fleshy to form a red receptacle (or 'foot') situated below the seed.

An endemic species found throughout New Zealand from lowland to mountain forest.
