MILLER AND STANDLEY—NORTH AMERICAN NYMPHAEA. 65 
of the University of Pennsylvania, the Philadelphia Academy of 
Natural Science, the New York Botanical Garden and Columbia 
College, the Gray Herbarium, and the Missouri Botanical Garden 
(this containing the types of the Engelmann Herbarium), together 
with certain material from the University of California, that in the 
private herbarium of Dr. E. L. Greene, and, finally, all that in the 
National Herbarium. To those who have charge of these collections 
we are deeply indebted, either for the loan of the specimens or for 
facilities for their study. In addition, we are under obligations to 
the dozens of people all over the country who have responded to 
requests for living material. Their names, which are so numerous 
as to prohibit their full enumeration here, will be found in the lists 
of specimens examined. Without their assistance the work could 
not have been completed. 
HISTORY OF NAMES. 
NAMES APPLIED TO GENERA. 
Blephara J. E. Smith, Mem. & Corr, 1: 577. 1882. 
Before publishing the name Nuphar, Smith sent a diagnosis of the 
genus under the name Blephara to the Bishop of Carlisle in a letter 
dated November 17, 1808. This letter is printed in the ‘‘Memoir and 
Correspondence,” thus giving the name Blephara a definite status. 
The type is given as Nymphaea lutea. 
Nuphar J. E. Smith in Sibth. Fl. Graec. Prodr. 1: 361. 1808 or 1809 (title page 
dated 1806, but part containing this name not printed before December, 1808). 
Type, by monotypy, Nymphaea lutea L. A synonym of Nymphaea 
L., as restricted by Salisbury in 1806, and of Nymphozanthus 
L. C. Richard, May, 1808. 
Nymphaea L. Sp. Pl. 510. 1753. 
Type, N. lutea L. The genus originally contained the species lutea 
(misprinted lusea), alba, lotos, and nelumbo, representing the modern 
genera Nymphaea (lutea), Castalia Salisb., 1806 (alba and lotos), and 
Nelumbo Adans., 1763 (nelumbo). No type was designated, nor 
was any clue furnished to the author's intention. 
Under the American code of Botanical Nomenclature the types of 
the genera of Linneus’ Species Plantarum are to be determined 
through the citations given in his Genera Plantarum (1754). On 
page 227 of this work are cited under Nymphaea Tournefort’s plates 
137 and 138. These represent the white-flowered Castalia alba and 
the yellow-flowered Nymphaea lutea. Since Linneus gives no specific 
indication that either was the type of his genus, the first of the 
Linnean species common to the two works is to be regarded as the 
type. This is Nymphaea lutea L.
