probably say that it is not valid for the citation of genera; but I 
do not see that this should be the case, however it may militate 
against Hill being cited as the author of the specific name, which 
in one of these instances happens to comply with the Linnean 
plan. Even if we ignore Hill, we shall find that Miller, in the 
sixth and seventh editions of the ‘Gardener’s Dictionary’ of 
1752 and 1759, bad also taken the same line; but these again 
are editions in which the binomial system is not adopted. 
In the eighth edition of 1768, however, the reformed plan is 
followed, and there are three species described, namely: Statice 
Armeria, which is the Armeria elongata of Link; Statice minor, 
which is the A. alpina of Willdenow; and Statice maritima, 
our Sea-Thrift, and which, following Nyman and other authors, 
we shall connect with the Holotrichous Armeria maritima. 
In addition to Hill and Miller, Fabricius in the ‘Enume- 
ratio... . plantarum ... Helmstadtiensis’ also uses the 
Tournefortian names of the genera in the same way; as does 
Adanson in the ‘Familles des Plantes’ of 1763, and Moench 
m the ‘ Methodus’ of 1794, and other authors. Moreover, 
Medikus in ‘ Staatsw. Vorles. Churpf. Phys.-Oek. Gesell.’ (1799), 
p- 228, used the name Polyanthemum for the Thrifts before the 
establishment of Willdenow’s genus Armeria, which is therefore 
invalid from another cause, the only reason left for the retention 
being the powerful one, that of its being in nearly general use. 
Kuntze in his severely criticised ‘Revisio’ adopted the view 
I advocate, and it is tollowed in N. L. Britton’s ‘ List of Pteri- 
dophyta and Spermatophyta of North-eastern North America, 
and by N. L. Britton and A. Brown in their ‘Ilustrated Flora 
of the Northern States and Canada.’ 
I now give the results of my examination of British specimens 
of the Thrifts which belong to the Pleurotrichous Armeria 
pubescens, Link, from the following localities :— 
Cobo, Guernsey (“4. duriuscula”’); Tors near the sea, Ilfra- 
combe (Herb. Bab. 1848); Torr Cross, 8S. Devon; Portland, 
Dorset; Littlehampton, Hastings, Sussex ; Gravesend, E. Kent; 
Porlock Weir, Somerset ; Wells, Norfolk; Aber coast, Pwlheli 
coast, Crib Goch (Dillenius, 1726), Snowdon (Herb. Bab. 1847 
and Twl Dhu 18382, as alpina), Ciogwyn du yr Arddu, at 2200- 
2700 feet, Carnarvonshire; Dulas Bay, and Aberfrawy, An- 
glesey; Wainfleet, Lincolnshire (Rev. H. J. Riddelsdell); Hillno, 
Cheshire; Southport, Lancashire; Wensleydale, Yorkshire; Torr
