Dr. Jan Theodoor Henrard, former curator of the Gramineae at the Rijksherbarium, died at Leiden 28 August 1974, in his 93rd year. Among the staff-members of the Rijksherbarium there are only a few left who have known Dr. Henrard, as he retired in 1946 on reaching the age of 65. They will remember him as an enthusiastic taxonomist with a great love for the variation of living nature. He was always busy analyzing the often very slight differential characters of importance in the family to which he devoted a great part of his life, the Grasses.
