In spring it produces light green, tender, new leaves that contrast with the pale bark. The leaves are simple, alternate, ovate to acuminate in shape with three distinct veins from the base. The leaf margin is slightly toothed (specifically serrate) towards the apex, whereas the basal third tends to be entire. The new leaves are bright, fresh ...

Podocarpus (/ ˌ p oʊ d ə ˈ k ɑːr p ə s / [2]) is a genus of conifers, the most numerous and widely distributed of the podocarp family, the Podocarpaceae. Podocarpus species are evergreen shrubs or trees, usually from 1 to 25 m (3 to 82 ft) tall, known to reach 40 m (130 ft) at times.
In regions where dogwood anthracnose is a problem, homeowners and public land managers are encouraged to know the symptoms and inspect trees frequently. The selection of healthy, disease-free planting stock is essential and transplanting trees from the forest, particularly from mountain forests, should be avoided. [11]
Pollination occurs early the following spring, with the male cones 3–8 cm (1 + 1 ⁄ 4 – 3 + 1 ⁄ 4 in) long. The female (seed) cones mature in about 20 months from pollination; when mature, they are yellow-brown in color, 15–25 cm (6– 9 + 3 ⁄ 4 in) long, and 5–7 cm (2– 2 + 3 ⁄ 4 in) broad, opening to 12 cm ( 4 + 3 ⁄ 4 in ...
In many species with spirally arranged leaves, such as Abies grandis (pictured), the leaf bases are twisted to present the leaves in a very flat plane for maximum light capture. Leaf size varies from 2 mm in many scale-leaved species, up to 400 mm long in the needles of some pines (e.g. Apache pine, Pinus engelmannii ).
The leaves can be mistaken for those of the catalpa. The very fragrant flowers, large and violet-blue in colour [14] are produced before the leaves in early spring, on panicles 10–30 centimetres (4–12 in) long, with a tubular purple corolla4–6 centimetres (1 + 1 ⁄ 2 – 2 + 1 ⁄ 4 in) long resembling a foxglove flower.
