I suspect that Tahitia Burret (I.e. 609), based on Berrya vescoana Baillon and created by Burret on the strength of the description of Baillon and a plate of Drake del Castillo, should also be included in Berrya; the differences with Berrya, as stated by Burret are very small indeed and do not merit to be evaluated as being on the generic level. Without proper material at hand, however, I prefer to defer a final decision. R E I N W A R D T I A Published by Herbarium Bogoriense, Bogor, Indonesia Volume 7, Part 5, pp. 425-431 (1969) KAYEA Wall, and MESUA L. (Guttiferae) A. J. G. H. KOSTERMANS * Kayea Wallich, PI. As. rar. 3: 5. 1832 and Mesua L., Spec. PI. 515. 1753 are very closely related. Bentham and Hooker (Gen. PI. 1: 176. 1862) distinguished both genera in this way, that Kayea has a one-celled ovarium with one seed and a 4-fid style, whereas Mesua has a 2-celled ovary and 4 ovules, the stigma being peltate. This distinction has been maintained by other botanists, but Anderson (in Hooker f., Fl. Brit. Ind. 1: 259. 1874) encountered already a difficulty with the species M. lepidota Anders., which as he says: "might represent a new genus in between Kayea and Mesua", bringing the two still closer together. Some years ago I started to revise Kayea and Mesua in conjunction with my monograph on, Mammea L. (including Ochrocarpus). Lack of adequate material of several species compelled me to postpone the final revision, untill such materials should be available. Meanwhile it has become clear that the two genera cannot be sepa- rated. Collections from living Mesua ferrea trees in the Botanic Garden in Bogor, proved that on the same tree of Mesua ferrea L. two- and one- celled fruit may be found With one or two seeds. In other Kayea species two-seeded fruit were observed. The shape of the stigma cannot be used as a generic characteristic as between the peltate one of Mesua ferrea (which sometimes is ineised) and the more or less 4-fid ones of Kayea there are all gradations. As in all other respects the two> genera are completely alike, I had decided long ago to merge them under Mesua. As I have been pressed to publish the new combinations, which I have written on the herbarium labels in many herbaria, I herewith give a list of the new combinations, in anticipation of the forthcoming mono- graphic revision. *) Forest Research Institute and Herbarium Bogoriense, Bogor. — 425 — 426 R E I N W A R D T I A [VOL. 7 1.
