THEIR NOMENCLATURE. 439 
the whole plants of the former would seldom be accessible for 
examination in the study, because only fragments of such large 
plants could be conveniently preserved in the herbarium. Eventu- 
ally, it was found necessary to discard Smith’s name of majus ; 
because the species of Jacquin, to which that specific uame more 
properly belonged, was different from Smith's plant, and one not 
found in Britain. Unfortunately, too, the same name majus had 
been used earlier for our British species flavum ; the consequence 
being, that at later dates some of the localities for flavum were 
mis-assigned to Smith’s majus in books, ea. gr. in the original 
‘ Botanist’s Guide,’ page 37. 
The subsequent changes will best be shewn through the 
successive editions of the ‘ Manual of British Botany.’ In the first 
and second editions the accustomed names of minus and majus were 
still retained, and the species were treated accordingly as two only. 
In the third edition of that work (1851) a change began. Two other 
names, those of fleruoswm and saxatile, to represent newer species 
carved off from the two older, were placed between minus and 
majus ; both the latter still retained there, and thus raising the 
alleged species from two to four. The two new names were both 
applied to plants at Cheddar, in Somerset ; making it appear that 
two distinct species had been found in that locality; the latter 
name of the two being also applied to a plant from Brathay 
(by Windermere), in Westmoreland. In preceding books the 
Cheddar plants had been designated minus, as a single species. 
The plant of Brathay had probably been named the same; as, 
under the county of Westmoreland, in the ‘ Botanist’s Guide,’ we 
find Dawson Turner recording minus on the borders of Winder- 
mere, and majus located only on the “ banks of Ullswater.” The 
former is the plant erroneously published as flavum in Martineau's 
Guide to the Lakes. 
Tn the fourth edition of the ‘Manual’ comes a further change. 
T. majus of Smith ceases to be a distinct species, and its name is 
made a synonym of flecuosum. The number of species is thus 
reduced back from four into three. In the same edition the 
T. Kochii of Fries is entered as a synonym of 7. savatile ; the
