84 Rhodora [APRIL 
with A. laciniata L., has generally passed as A. arenaria Woods, and 
has recently been treated as A. sabulosa Rouy by Moss & Wilmott ! 
in their important revision of British Atriplices. 
Although the diagnostic characters of this species are quite dis- 
tinctive and make it unique among indigenous North American forms, 
the determination of the name by which it should be known is a matter 
of some difficulty. It apparently formed a part of the original Atriplex 
laciniata L.? and was referred to by Linnaeus in the Flora Anglica? 
as A. maritima, a name discarded by Moss & Wilmott as a lapsus 
calami, Woods* in 1849 published the plant as a new species under 
the name A. arenaria, replaced by Rouy 5 in 1890 by A. sabulosa on 
account of the prior use of the name A. arenaria by Nuttall 5 for a 
related species of our eastern American coast. The name Atriplex 
maritimum had in the meantime been independently given to the 
species by Ernst Hallier in a revision of the Atriplices of Heligoland. 
According to International Rules, Hallier’s name should be used for the 
plant in view of the fact that the three previous uses of this binomial 
are untenable.” 
In the Index Kewensis Rafinesque’s Atriplex mucronata è is referred 
to A. arenaria Nutt. If this were correct the name would require 
adoption for the latter species, and Woods's A. arenaria would then be 
available for the present plant. But the method of publication of 4. 
mucronata does not seem to the writer to justify its adoption, although 
a specimen of A. arenaria Nutt. from “maritime New York" in the 
Prodromus Herbarium, labeled A. mucronata by Rafinesque himself, 
shows that the name was intended by him to apply to that species. 
It was merely mentioned incidentally by Rafinesque in a review of 
Pursh's Flora: “His Atriplex halimus, A. laciniata, A. hastata, are 
different from the European species and have been called A. hali- 
moides, A. mucronata, and A. dioica by Rafinesque.” Names so :

synonymy.

7 A. maritima L. 1. c. is considered by Moss & Wilmott to have been adopted by 
Linnaeus from Ray through a lapsus, an interpretation which seems justifled by the 
fact that the name was never afterwards used by Linnaeus; A. maritima (L.) Crantz, 
Inst. i. 208 (1766) is Suaeda maritima (L.) Dumort.; A. maritima Pall. Reise ii. 289 
(1773) is a mere nomen.
