Trees

Name: 눈잣나무/ 누운잣나무 (Nunjatnamu)
Scientific name: Pinus pumila (Pall.) Regel
Type: evergreen with needles, shrub-like and arborescent
Blooming season: June to July
Bearing season: next September
Distribution: Gangwon-do (Gangwon Province)

This coniferous evergreen shrub grows 4-5 meters high and is 15 centimeters in diameter. In the flatlands it tends to grow straight upward while in the mountains it can be a bit slanted. The bark is dark brown. The needles are formed in bundles of five. There are three to four stomata on each side of the needles. This monoecious tree gives bloom to a male flower on the basal branches and a purple female flower at the tip of the branches. It bears an egg-shaped cone. The seeds change color from green-brown to yellow-brown with the passing of time.

This rare plant is vulnerable to air pollution and is quite uncommon in urban regions.

Herbs & Flowers

Name: 거미고사리 (Geomi gosari, Spider bracken)
Scientific name: Asplenium ruprechtii Kurata
Full bloom: propagation by spore
Distribution: mountains nationwide

This fern grows 5-15 centimeters high in rocks and mountains. The short and tiny subterranean roots grow in bundles. The leaf stalk is light green and grows 1-10 centimeters high. The sorus forms on a vein. The linear, projecting sorus is arranged on both sides of the columella. The indusium breaks frontward.

A gemma formed from the columella lands on the ground and new shoots stretch out in all directions. This process resembles a spider’s web. Thus, it is called Spider bracken.
