as “a native of Northern Canada....but not of the United States,” 
and Pursh’s error has in this case not caused the confusion that has 
resulted from some of his other doubtful records. 
The first really satisfactory exposition of the species of Statice 
(Armeria) was made by the keen botanist Wallroth t in 1844. Its spe- 
cies, of which twenty-seven were recognized, were divided by him into 
three sections based on the pubescence of the fruiting calyx: Mastru- 
catae, with calyx-tube pubescent between as well as on the ribs; 
Barbatae, with calyx-tube pubescent only on the ribs; and Calvae, with 
tube glabrous. The first two sections were each subdivided according 
to the nature of the attachment between calyx and pedicel into two 
groups — Rostellatae, with the base of the calyx drawn out into a 
subacicular beak, and Truncatae, in which the point of attachment 
of the calyx was much shorter, and the calyx-base consequently 
less prolonged. The American species recognized were three, all 
described as new: Armeria labradorica, the only eastern species, of 
the Mastrucatae Truncatae; and A. arctica, based on the Armeria 
vulgaris forma arctica of Chamisso, from the Alaskan coast and is- 
lands, and A. sanguinolenta, from “Sumpfen Nordamerika’s,” both of 
the Barbatae Truncatae. In Boissier’s monograph? of Armeria in 
1848 two primary divisions of the genus were recognized. Macro- 
centron, corresponded in general to Wallroth’s two groups called Rostel- 
latae, with his Calvae, while Plagiobasis embraced all the remaining 
species. The second and much larger section, Plagiobasis, including 
all the American species, was divided into § 1. Holotrichae, answer- 
ing to Wallroth’s Mastrucatae T'runcatae, with calyx pubescent both 
on and between the ribs, and § 2. Pleurotrichae, equalling Wallroth’s 
Barbatae Truncatae, with calyx pubescent only on the ribs. Wallroth’s 
three North American species were recognized, and A. andina Poepp. 
B. californica was described from California. 
Despite their recognition by Boissier, and the fact that by him as 
by their describer they were considered referable to two distinct sec- 
tions or subsections, no notice of Wallroth’s species seems to have 
been taken in American botanical literature in the seventy-two years 
since their publication. Gray? in 1878, treating of Armeria vulgaris 
Willd. from North America, described it as having the calyx-tube
