Cedric Lambert Porter (1905-2000)

From: Hartman, R. L. and Burrell E. Nelson. 2000. Cedric Lambert Porter (1905-2000). Taxon 49: 577--580.


Dr. Cedric Lambert "Ted" Porter of Sun City, Arizona died Jan. 8, 2000 in Peoria, Arizona. He was born, Jan. 15, 1905, in Gujranwala, India (now Pakistan, near the foothills of the Himalayas) of American and British missionaries. His father was president of Gordon College, an institution operated jointly by an American missionary group and the Indian office of education. Porter attended a British primary school and, at age 14, was brought to the United States to attend high school in Ohio. He initiated college work at Wooster College, Ohio, but transferred to the University of Michigan were he completed a B.S. (1928) and a M.S. (1929) degree. In 1929 he married his classmate Marjorie L. Woollett and they came west to Laramie in a Model T Ford. He became instructor of Botany (1929-32, asst. prof. 1932-38; assoc. prof. 1939-42; prof. 1943) and swimming coach (1929-32) at the University of Wyoming. For his first six years, he spent summers collecting mosses throughout Wyoming and did graduate work at the University of Washington (sabbatical leave, 1935-36; Ph.D. 1937). His dissertation was entitled "Bryophytes of Wyoming." In 1937 he became assistant curator of the Rocky Mountain Herbarium (RM; curator, 1943) to provide for an orderly transition upon Aven Nelson's retirement.

During his curatorship the RM grew from 192,420 accessions to 284,531. This included the incorporation of the herbarium of Harry Hapeman, a physician from Minden, Nebraska (ca. 25,000 specimens; this gift, negotiated years earlier by Nelson).

Porter collected throughout Wyoming, parts of Colorado (often with H. D. Harrington), and in other Rocky Mountain states. Total numbered collections up to his retirement in 1968 was 10,579, but for many years he had collected in sets of 20 (19 duplicates for each numbered collection). These duplicates were used in an extensive exchange program primarily with North American herbaria.

To his credit upon retirement, the RM was probably the best organized, curated, and housed medium-sized herbarium in the nation. A repeated theme of his annual reports was the recognition, segregation, and curation of type specimens (ca. 4,500, paratypes included), the general updating of the nomenclature, the segregation of Wyoming specimens in red folders, the remainder in manila folders (he lettered every one with a Leroy Lettering Set, evenings and weekends), the development of a cardfile system for reprints and library accessions, and the development of an invaluable set of dot maps for the flora of Wyoming (on 4 by 5" cards). In 1960, the RM was moved from the east half, 4th floor, Engineering Building (home since 1926) to the 3rd floor of the former library building, newly renovated and renamed the Aven Nelson Memorial Building. This finally relieved the chronic shortage of space.

In 1959, Porter produced the popular text "Taxonomy of Vascular Plants" (W. H. Freeman and Co.; second edition, 1967). He published more than 40 scientific papers, "Spring Flora of Southeastern Wyoming," and eight fascicles of "A Flora of Wyoming" (ferns and fern allies, gymnosperms, angiosperms: monocots, dicots through Fumariaceae; Englerian system). This was preceded by the mimeographed "Contributions Toward a Flora of Wyoming" (Leaflet nos. 3-35, 1944-1965, six by contributing authors). His major interests included Rocky Mountain vascular plants, especially grasses and legumes, poisonous plants, and aquatics.

Master's students included Charlotte Goodding Reeder (academic advisor; she worked closely with Nelson), Michael Canoso, George W. Argus, Ronald J. Taylor, and Richard C. Scott.

C. L. Porter published seven species and two varieties new to science: Astragalus beathii (1941), A. hamiltonii (1952), A. racemosus Pursh var. treleasei (1945), A. schmollae (1945), A. spectabilis (1952), Hermidium alipes S. Watson var. pallidum (1952), Oxytropis obnapiformis (1947), Peteria pinetorum (1957), and Sphaeralcea procera (1943). In 1951 a distinctive sagebrush, endemic to the Wind River Basin, Wyoming, discovered by Porter was named in his honor by Arthur Cronquist: Artemisia porteri.

His wife, Marjorie passed away March 4, 2000; he is survived by children, Richard B. Porter, Kenneth R. Porter, and Carol L. Murray, all of Colorado; eight grandchildren; seven great-grandchildren; two nieces and a nephew.
