M.S. Clemens: Born: 1873, Liberty, New York, U.S.A. Died: 1968, Chermside Garden Settlement, Brisbane, Australia
The former Chaplain of the American Army since 1902. He and chiefly his wife made large collections of plants in the Malayan region, and besides in China (1912-14), Indo-China (1928) and the U.S.A. In later years, when Clemens was in active service no more, he charged himself especially with the administration and arrangement of the collections. When in New Guinea he died of food poisoning; his wife dauntlessly proceeded on her field work. Late in Dec. 1941, or early in Jan. 1942, she was evacuated from Lae tot Port Darwin, North. Territory, Australia, and is now at Brisbane, Queensland, Australia.
Several plants were named after her and her husband.

Brussels [BR] (899), and certainly in many other herbaria. The New Guinea collection is numbered from 1 onwards and probably exceeds 10.000; much of the material is scrappy and in a bad state. Being evacuated by plane she was forced to leave behind all of her equipment and her assembled botanical collections; it is assumed that all this material has been lost or destroyed.
Mosses from New Guinea evidently in Herb. Tokyo [TI], as the Tokyo Science Museum forwarded them to A. Noguchi for identification (cf. sub Literature 6). Her collection of the last ten months in New Guinea on Mt Sarawaket had to be left behind in store-rooms, when she was evacuated to Australia herself, and was destroyed by fire. Dupl. from the Philippines (1928) in Herb. Copenh. [C]; large Borneo collection (1931-33) in Herb. Hamburg [HBG]; also Borneo plants in Herb. Leningrad [LE].
