The commonly held view, he noted, was that the best varieties came from Isonandra gutta.
He observed that there were two varieties required for cable production; first, the variety including Dichopsis, Palaquium, and Isonandra (which were really all the same) (42) and, secondly, the 'Paienna' [Payena].
Moreover, it was unlikely that French officials would endorse or invest in plantations of such trees as they too would not want to risk growing a product that might not be successful--it could be grown as an adjunct to the more important varieties (Palaquium or Isonandra), but probably no more than that.
