Dear Mr. Gamble¹

D^r. Koorders² has kindly sent me a copy of his big book on the Flora of N. E. Celebes.³ I find that the island agrees with the Philippines in possessing Oaks (Quercus Sp.) and Dipterocarps.

Do you know if either of these have been recorded anywhere further East? If not, it shows that my Oriental and Australian Regions, — do [2] apply to plants as well as to animals — as showing very ancient land connections or isolation —

As my book⁴ is now in the press — (first proofs) I shall be greatly obliged if you can answer this question as soon as you can.

Yours very truly I Alfred R. Wallace [signature]
