None known
Other Uses
Tannin;  Wood.

Tannin is obtained from the bark[266]. Wood - light, soft, not very durable. Used for interior work, construction, wood pulp etc[46, 61, 266].
Cultivation details                                         
Prefers a good moist but not water-logged soil[11]. Grows well in heavy clay soils. Plants are very shade tolerant, especially when young, but growth is slower in dense shade[81]. Intolerant of atmospheric pollution[1]. Prefers slightly acid conditions down to a pH of about 5[200]. Prefers growing on a north-facing slope[200]. This species comes from an area of very high rainfall and does not normally thrive in Britain[11]. It is also very susceptible to damage by late frosts[1, 11]. It grows best in the cooler wetter parts of Britain, such as the Perthshire valleys of Scotland and the far west[11]. Some trees are thriving in these areas[185]. Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm in height. Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance[200]. Plants are strongly outbreeding, self-fertilized seed usually grows poorly[200]. They hybridize freely with other members of this genus[200]. Closely related to A. recurvata and A. squamata[11].
                                                                                 
Propagation                                         
Seed - sow early February in a greenhouse or outdoors in March[78]. Germination is often poor, usually taking about 6 - 8 weeks[78]. Stratification is said to produce a more even germination so it is probably best to sow the seed in a cold frame as soon as it is ripe in the autumn[80, 113]. The seed remains viable for up to 5 years if it is well stored[113]. When large enough to handle, prick the seedlings out into individual pots and grow them on for at least their first winter in pots. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Alternatively, if you have sufficient seed, it is possible to sow in an outdoor seedbed. One report says that it is best to grow the seedlings on in the shade at a density of about 550 plants per square metre[78] whilst another report says that they are best grown on in a sunny position[80].

[1]F. Chittendon. RHS Dictionary of Plants plus Supplement. 1956
Comprehensive listing of species and how to grow them. Somewhat outdated, it has been replaces in 1992 by a new dictionary (see [200]).
[11]Bean. W. Trees and Shrubs Hardy in Great Britain. Vol 1 - 4 and Supplement.
A classic with a wealth of information on the plants, but poor on pictures.
[46]Uphof. J. C. Th. Dictionary of Economic Plants.
An excellent and very comprehensive guide but it only gives very short descriptions of the uses without any details of how to utilize the plants. Not for the casual reader.
[61]Usher. G. A Dictionary of Plants Used by Man.
Forget the sexist title, this is one of the best books on the subject. Lists a very extensive range of useful plants from around the world with very brief details of the uses. Not for the casual reader.
[78]Sheat. W. G. Propagation of Trees, Shrubs and Conifers.
A bit dated but a good book on propagation techniques with specific details for a wide range of plants.
[80]McMillan-Browse. P. Hardy Woody Plants from Seed.
Does not deal with many species but it is very comprehensive on those that it does cover. Not for casual reading.
[81]Rushforth. K. Conifers.
Deals with conifers that can be grown outdoors in Britain. Good notes on cultivation and a few bits about plant uses.
[109]Wilson. E. H. Plantae Wilsonae.
Details of the palnts collected by the plant collector E. H. Wilson on his travels in China. Gives some habitats. Not for the casual reader.

A very detailed book on propagating trees. Not for the casual reader.

A bit out of date (first published in 1972), but an excellent guide to how well the various species of conifers grow in Britain giving locations of trees.

Excellent and very comprehensive, though it contains a number of silly mistakes. Readable yet also very detailed.

On-line version of the Flora - an excellent resource giving basic info on habitat and some uses.
