When identifying most plants, a closer observation helps establish key visual clues. Pinus wallichiana, Himalayan Pine needles at inches-long are longer than the other 5-needle species mentioned.

This during the later life of the great Sir Joseph Banks , who believed in the internationalism of science, and successfully caused almost every ship sailing to Britain from any British colony to carry plants.

Besides Pinus wallichiana he was also commemorated in plant taxonomy with Taxus wallichiana , Ulmus wallichiana , Lilium wallichiana, Dryopteris wallichiana , Schefflera wallichiana , Geranium wallichianum , and Rubus wallichii , among others.

Growing Concerns: Sphaeropsis attacks province's pines

Diplodia tip blight is a common fungal disease of Austrian pine, although Scots, mugo, and red pine may also be affected. The Diplodia fungus infects the growing buds and shoots, causing the newest needles of a tree to be stunted and brown. These needles appear as short brown tufts at the ends of the branches. Small black reproductive structures of the fungus can be seen at the base of these stunted needles. The Diplodia fungus more properly called Sphaeropsis also produces spores in fruiting structures that develop on the second-year female cones. These spores are carried by rain throughout the tree.
