BRITISH SEA-THRIFTS AND SEA-LAVENDERS. 67 
var. alpina, but this, as his herbarium shows, is based on a speci- 
men gathered by him on Twll Dhu, Carnarvonshire, in 1832, which 
differs in “being only more constantly hairy”; but in the second 
edition of the Manual (1847), p. 261, he describes it as having 
“broader leaves” and “with petals 3 as long as the villose-striate 
tube of the calyx,” and there is a specimen in his herbarium 
from Snowdon gathered in 1847. Neither of these has anything 
to do with Armeria alpina, Willd. (which is a plant of the moun- 
tains of Central Europe), and they are scarcely separable from the 
coast form of A. pubescens, Link. In the third edition, p. 262 
(1851), he describes var. pubescens (Link), and refers to the 
“Engl. Bot. plate no. 226” of the first edition as representing 
it, and says “ the calyx-tube is hairy on the ribs only.” In the 
seventh edition of 1874 three varieties are given :—var. a.maritima 
(Willd.) (which he says is synonymous with A. maritima, Boiss., 
and .1. pubescens, Link); var. b. planifolia (the variety established 
by Syme in the third edition of English Botany, vol. vii. p. 158, 
under A. vulgaris, Benth., and figured on plate 1153); and var. c. 
duriuscula, Bab., described as having very slender 1-veined sub- 
triquetrous leaves. 
In 1848 the genus Armeria was monographed by Boissier for 
De Candolle’s ‘ Prodromus’ (vol. xii. pp. 674-689); and the 
author divides the genus into two sections—1. Macrocentron, and 
2. Plagiobasis; the latter contained the British species. Boissier 
has again divided Plagiobasis into two groups: i. Holotriche, 
characterized “Tubus calycinus totus et ad costas et ad costarum 
intervalla pilosus”; and ii. the Pleurotriche, with ““Tubus calycis 
ad costas tantum pilosus, intervallis costarum glabris.” 
In section 1 he puts A. maritima, Willd., Enum. Hort. Berol. 
1. p. 833, which he says occurs in “Suecia et Norvegia, Anglia, 
Hibernia, Germania boreali et Gallia occidentali.” To this 
group he also puts A. pubigera: “Ab A. maritima sat differre 
Videtur caule basi suffrutescente foliis 1-1} pollic. rigidis tri- 
quetris regulariter in rosulam more Acantholimonis congestis. 
B scotica, pubescentia foliorum rariori, involucro glabro. In Insula 
Stafla Scotie ubi Seapink dicitur legit cl. A-DC.” 
In Pleurotriche Boissier puts A. pubescens, Link, in ‘ Repert. 
Nat. Cur. Berol. i. p- 180°... “In arenosis presertim maritimis 
Suecia in Hallandiw, Germanie septent., Anglia et Scotie (hic 
Quoque in montibus ex herb. gen. Berol.), Galliw Islandie .. .” 
It is the Statice elongata yar. pubescens of Koch, Syn. p. 595
