Notes
When SCHEFFER described Quercus bancana he had specimens with flowers and young cupules, and apparently also some detached, ripe cupules. A year later (1871) he stated that the detached, ripe cupules on which he based his description of Quercus bancana, did not belong to the species, and he replaced it with another one, based on a specimen collected by TEYSMANN (HB 7639) from Pangkal Pinang in Banka, which, however, belongs to L. urceolaris. HANCE, who never saw the type of Quercus bancana SCHEFF. (1870), described Quercus rajah based on specimens collected from a tree cultivated in the Bogor Botanic Gardens, the seedlings (or seeds?) of which had been brought back by TEYSMANN from Banka. These specimens are exactly the same with SCHEFFER'S Quercus bancana (1870). Believing that SCHEFFER'S identification (1871) was correct, KING (1889) and most later authors, who never checked the type of Quercus bancana, referred all specimens of the true bancana to rajah, and the true urceolaris to bancana. These two species are, however, perfectly different from one another by the characters of the leaf and cupule (see the key).
The material from New Guinea cited by MARK-GRAF under Pasania bancana, belongs to L. mega-carpus.
