A well-known deciduous conifer, 80-100 ft. high, grown in hundreds of thousands for forest purposes. There are several varieties, including pendula, with weeping habit. Owing to lack of cultivation and badly ventilated soil, plantations are sometimes attacked by a minute fungus (Peziza Willkommi), which spreads rapidly. The Japanese Larch (leptolepis) is a beautiful tree, but not so valuable economically as the common one. The Golden Larch (Pseudolarix Kannpferi), which attains a height of 130 ft. in China, resembles the European Larch in appearance, but the foliage, at first bright-yellowish green, turns to golden yellow in autumn.
