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.



Name: 검은비늘버섯 (Geomun bineul beoseot, Black scaled mushroom)
Scientific name: Pholiota adipose (Batsch) P. Kumm.
Type: saprophile spore
Print: red brown

This mushroom grows in bundles from the stumps and branches of fallen and dead broad-leaved trees. The pileus has an average diameter of 8 to 12 centimeters and gets flat and wide near the top. The surface is yellow with some viscosity. It shines when dried. The edge of the pileus is lemon yellow. The color of the scale bark ranges from white to brown. The attached gills are in spectrums from lemon yellow to brown. The stipe is from 5 to 15 millimeters high. The thick scale ranges from yellow-brown to brown. It has a fibrous annulus with a high viscosity.


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.

*This series of articles about Korea’s insects, trees, mushrooms and herbs & flowers has been made possible with the cooperation of the Korea National Arboretum.
