Career

Norris received his B.S. in botany from Michigan State University in 1954. In 1964, he obtained his Ph.D. from the University of Tennessee in botany, advised by Jack Sharp.[2] While there, he was a member of Sigma Xi.[3] Norris became a professor of botany at Humboldt State University in 1967. Between 1984 and 1985, Norris was a Fulbright Research Scholar at the University of Helsinki. In 1990, Norris was awarded with an honorary Ph.D. by the University of Helsinki. After his retirement in 1991, he transferred his extensive brylogical collection to the University of California, Berkeley to continue his research.[2]

Throughout his lifetime, Norris collected about 116,000 bryophyte specimens. His main areas of focus were in California and Papua New Guinea, however, he made major collections on every continent other than Antarctica.

Norris described four moss genera as new to science; Bryolawtonia, Orthothuidium, Stoneobryum, and Unclejackia.[4] He has also authored or co-authored the following new species: Anomobryum hyalinum, Amomobryum ochii, Brachymenium wabagense, Brachymenium huonii, Bryum pseudoblandum, Dicranella papua-palustris, Dicranum cutlackii, Didymodon coffeatus, Didymodon wisselii, Diphyscium chiapense, Hampeella concavifolia, Hyophila streimannii, Leptocladiella flagellaris, Macrocoma gastonyi, Merrilliobryum tanianum, Microdus friedensis, Orthotrichum kellmanii, Orthotrichum shevockii, Orthotrichum spjutii, Oxystegus crassicostatus, Plagiomnium cordatum, Powellia parvula, Rhamphidium novoguineensis, Splachnobryum limbatum, Stereophyllum dicksonii, Syrrhopodon curticancellinatus, and Trematodon papuensis.[3]

Legacy

Norris is the namesake of two genera: Bryonorrisia and Timodania; 1 flowering plant species: Brongniartia norrisii; and 12 bryophyte species: Aphanolejeunea norrisii, Codriophorus norrisii, Didymodon norrisii, Lepicolea norrisii, Macromitrium norrisianum, Orthotrichum norrisii, Pogonatum norrisii, Radula norrisii, Scopelophila norrisii, Trematodon norrisii, Orthotrichum norrisii, and Trematodon norrisii.[3]

The daylily cultivar Hemerocallis 'Daniel Howard Norris' also bears his name.[5]
