As the new Index Herbariorum Part I: The herbaria of the world, ed. 8 (1990) will not be available to many readers in the Malesian area, an excerpt of the Institutes presented there plus some not included is given here. I have taken Malesia in a somewhat broader sense than usual and have included the Andamans and Solomons. I have noticed that especially telephone and fax numbers have changed in several instances, so check yours! Please notify me of any errors, omissions, or changes. — J.F. Veldkamp.
