It is easiest to reply by providing the text for my account of Araucaria 
bidwillii that will appear in my forthcoming book 'New Trees, Introductions 
to Cultivation 1970-2005' which will be published by the Royal Botanic 
Gardens, Kew, in about a year's time.

(formal description omitted)
The Bunya Pine is a magnificent tree in its native Queensland, and is grown 
quite widely in Australia and elsewhere for its ornamental value (Elliott & 
Jones 1982). Mature trees are somewhat hazardous on account of the risk of 
being hit by a falling cone. At present there seems to be little risk of 
this in our area [North America north of San Francisco and the NC/SC 
boundary, Europe north of the Mediterranean basin], where A. bidwillii is on 
the very edge of its tolerance, even in the mildest locations. It has 
however reached 11 m (33 cm dbh) in the past at Glendurgan, Cornwall (TROBI 
record from 1965) and the current British and Irish champion is a 6 m 
specimen at Earlscliffe, Baily, Co. Dublin (TROBI). It is therefore worth 
the attempt in the mildest coastal areas of Europe and western North 
America, but great size and longevity are perhaps too much to hope for.

TROBI = Tree Register of the British Isles

I'd better get on with the book itself!
