considered synonymous, and the two former, /-'. angustifoliuin 

 and P. liiiearc, published in 1826, are referred to the P. Ncesii 

 Kunth, described in 1829, a rather queer procedure, where the 

 rule is that the oldest binomial shall be taken up, for certainly, 

 if it is necessary to unite P. angustifolium and P. lincare, the 

 former being invalidated by the earlier publication of LeConte's 

 name, P. liiicarc is available.

ONAGRA GRANDIFLORA (AIT.)* A SPECIES TO BE 

 INCLUDED IN THE NORTH AMERICAN FLORA 



By Anna Murray Vah, 



In searching through several herbaria for specimens of Onagr'a 

 LcDJiarckiana that had grown wild in North America, it became 

 apparent that there was a large-flowered evening-primrose which, 

 though closely related to 0. Lamarckiaiia, could not be referred 

 to that plant as it is known in Europe in the wild state and in 

 cultivation. 



The reference by Bartram f to a large-flowered evening-prim- 

 rose seen near Tensaw, Alabama, suggested the possibility of 

 finding the plant still growing in the locality where he found it in 

 August, 1776. Professor S. M. Tracy kindly undertook the 

 search for it, and on August 16, 1904, he re-discovered the locality, 

 and the plant, described so vividly by Bartram as " the most 

 pompous and brilliant herbaceous plant yet known to exist." 



Abundant material was sent to the New York Botanical Garden 

 and extensive cultures of 0. grandiflora have been begun, in an 

 attempt to establish its relation with its allies. Further details 

 will be included in an article now in press. 



OcnotJicra grandifiora Ait. was based on a plant introduced 

 from North America by John P'othergill in 1778. The plate
