Schultes, comb. nov.

Ed. 2, 1 (1891) 62. 
Dr. Tom E. Lockwood monographed the genus Brugmansia 
for his Ph.D. thesis at Harvard University — A Taxonomic 
Revision of Brugmansia, Solanaceae, Unpubl., Cambridge, 
Mass. (1973) — but was prevented from publishing his 
nomenclatorial conclusions by his untimely death. That he fully 
intended to do so is indicated in his article in the Botanical 
Museum Leaflets, Harvard University 23 (1973) 281. In the 
meantime, he prepared the treatment of the genus Brugmansia 
for Hortus Third (Bailey, L.H. and E.Z. Bailey, (1976) 184, 
Macmillan, New York] in which ‘“‘B x insignis (Barb. Rodr.) 
Lockwood”’ is given. Since no basionym was cited, the new 
combination was not validly made. Lockwood considered 
Brugmansia x insignis to be a hybrid between B. suavelolens x 
B. versicolor. 
Inasmuch as there is a need for this binomial in connection 
with phytochemical publications, the above new combination is 
proposed.
