大唐西域記にみえる「多羅樹林」について

The Xuan Zang's Travels made mention of the forest of Tala-trees in Konkanapura, south India.
A. F. Rudolf Hoernle drew a conclusion that the Tala-tree was Corypha palm. It seems his result is to the point. However there have been some mistake during the proving process.
Hoernle says, in those days, there was just Corypha palm, Palmyra palm did not exist yet in India.
But Palmyra palm has already existed there in my opinion.
The forest of Tala-trees was a Corypha palm plantation. Corypha palm leaf was more exellent for writing materials than Palmyra palm one. So the plantation of Corypha palm was administered by Konkanapura.
