the plant was E. Hallier PPh n 1863, in a revision of the Atri- 
plices of Heligoland, publish ed it as a new species, A. maritimum |

just noted, is a pure synonym cintata a A. maritima (L. 
Crantz (Inst. i. 208 (1766) ) is aaa nt a (L.) Dumortier 
and A. maritima Pall. — ii. 289 (1773) ) is merely a nomen. 
All these uses of the e being invalid it is clear that by the 
ate are of the Internationa Code the name to be employed for 
e plant is ATRIPLEX MARITIMA KE. Hallier. The species is one 
a a number whose range, et on the coast of northwestern 
Europe, includes also the eastern coast of Canada. A. maritima 
is found in America in New Brunswick, Prince Edward Island, 
and the Magdalen Islands, the earliest American specimen I have 
seen being one in the British Museum collected by John Macoun 
on Prince Edward Island in 1888. 
NOTE ON ARTICLE 45 OF THE VIENNA CODE. 
By G. Cuaripce Druce, M.A. 
Tue suggested alteration in the names of the Sea Lavenders 
(Limonium) ape Thrifts eons) and the omen of the 
earlier names of Castalia and Nymphea more recent 
bearing in mind the earlier sentences, s uch a Aire e as that 
involved in the aubsuedian of the much later Armeria for Statice 
is necessitated. 
Article 45 reads :— When a genus is divided into two or more 
genera, the name must be kept and given to one of the principal 
divisions. If the genus Lass op a section or some other division, 
which, judging by its name or its species, is the type or the origin 
of the group, the name is ape for that part of it. If there is 
no such section or subdivision, but one of the parts detached 
contains a great many more species than the others, the name is 
reserved for that part of it.” This rule has been recently con- 
strued by M. Briquet* to demand the use of Nymphea vice 
Castalia, and the consequent restoration of Smith’s Nuphar of 
peak later date than Salisbury’s eels In this instance the 
i n genus consists of four species, one of which is a Nelwm- 
bium, gt are white, and the other a cullen water-lily—the latter 
stands first in the Species Plantarum. In his Genera Plantarum 
(17 , p- 227, Linneus has three sections, N. lutea, N. alba, and 
Nelu mbo, 80 when Salisbury in 1805 separated the two white- 
gb 
separated by Aetna ie in 1763), he left the first section to bear 
the name Lymphec a. It was not until three years cor and for
