WikiBotanicals:Cunninghamia

Cunninghamia (named after J. and A. Cunningham, two celebrated botanical collectors, the former being  the discoverer of this Conifer). This is a broad-leaved China Fir.

Background
An evergreen tree, not hardy except in very favoured spots. It is too large to be allowed space  in the greenhouse, and, when grown in the open, it is  almost invariably disfigured by the violence of winds and frost. With these impediments of primary importance,  the tree will never become largely grown ; it has, however, been frequently seen doing well. Cunninghamia requires a well-drained light soil, and is best propagated from seeds, as cuttings rarely make good plants.

Species
C. sinensis (Chinese), under name of C. lanceolate. flower, males in grouped catkins, which are terminal fascicled, cylindrical, and about 1in. long; females with   three ovules, cones about the size of a walnut, sessile, droopins,   globose, smooth; scales ovate-acuminate, coriaceous, sharply denticulated on the margin. I. sessile, deflexed, spreading in every direction, 1 1/2in. long, lanceolate, much pointed, rigid, flat, entire, somewhat scabrous on the margin. Branches for the most part verticillate, spreading horizontally. Trunk straight, cylindrical. Height reaches 40ft. to 50ft. (much less in Europe). China, 1804.
