Abstract
In the middle of January 2026, I was glad to be able to wish Professor Ivan Regula a happy 90th birthday. Professor Regula spent his entire professional career at the Division of Botany, Faculty of Science in Zagreb, teaching plant physiology to many generations of students. At the end of 2025, we celebrated the 150th anniversary of continuous botany teaching in Zagreb, marking the historical origins of today’s Division of Botany. The time spent with Professor Regula at that celebration brought back fond memories of the days when his presence at the Division was part of everyday life.
