As most of our readers who generally will have at hand a copy of the Flora Malesiana will have seen, the last part of volume 4 contains a most valuable list compiled by Mrs M.J. van Steenis-Kruseman and Mr W.T. Stearn on ”Dates of Publication”. Though aiming primarily for use of Flora Malesiana it is not limited to works dealing with the Malaysian region only but included all works which have come to our knowledge of which more precise data could be given than Pritzel gave eighty years ago. We are certain that quite a number of data have escaped our attention and we have also put forward that there is apparently no end to attain in this matter. It is for this reason that we continue this bibliographical information.-—Ed. Bentley, R. & H. Trimen, Medicinal plants.
