Larix gmelinii var. olgensis, synonym Larix olgensis,[1] the Olga Bay larch or Olgan larch, is a variety of larch.[2][3] The variety is named after Olga Bay in the Sea of Japan. The common name in Japanese language is 満洲唐松 (Manshu'u Kara-matsu). The common name in Chinese is 黄花落叶松 (pinyin: huang hua luo ye song).[4] This variety occurs in Central Sikhote-Alin, and rarely occurs in North Korea, and Jilin and eastern Heilongjiang provinces of China, between 500 and 1100 metres in elevation.[5][4]
This deciduous coniferous tree grows to 25–30 meters tall with a trunk reaching a meter in diameter at breast high, with gray to gray-brown bark with flaking and scaly fissured bark. Its leaves are needle-like, dark-green, 1.5–3 cm long and 1 cm wide. The reddish purple or violet cones mature to light brown, sometimes tinged with purple, and range from 18 to 25 mm long. Pollination occurs in May with seeds maturing in September-October. It grows in mountains and on moist slopes and in swamps. The timber has many uses in construction and for wood fiber. The trunk is used to produce resin while the bark is used for tannins.[4]

잎갈나무(학명: Larix olgensis var. koreana)는 한국·중국 등지에 분포하는 낙엽 침엽교목으로 이깔나무라고도 한다. 높이 37m, 지름 1m 정도이고 가지가 수평으로 퍼지거나 밑으로 처진다. 잎은 모여나며 짧은 가지의 것은 길이 15-30mm, 너비 1-1.5mm이며 긴 가지의 것은 길이 10–15 cm, 너비 2.8mm 정도이다. 꽃은 5월에 피며 암수한그루이고 수꽃이삭은 장타원형이며 암꽃이삭은 넓은 난형으로 황갈색이다. 열매는 구과로서 길이 15-35mm의 난형 또는 타원형이며 다갈색의 실편은 25-40개이고 9월경에 익는다.
