From this it is evident that the foliage of this variety 
should be of a deep bluish-green color, slightly blistered or 
smooth, with ruffled borders, and the lower leaves not 
petioled. All plants, therefore, that did not present these 
characters, were considered as being off type, and hence 
were not used in the description: Very many of our cab- 
bages were tabulated in the same manner. As far as prac- 
ticable the results thus obtained have been supplemented 
by comparison with the printed descriptions and illustra- 
tions of horticultural works, and seedsman’s catalogues, 
and by correspondence with experienced seed growers. 
SUB-VARIETIES. 
Several cabbages, as for instance the Surehead and Bergen 
Drumhead, known to seedsmen under different names, pre 
sented such close resemblances that many of the plants from 
one could have been placed in the other without the possi- 
bility of detection. Yet a difference was observable between 
the rows taken as a whole, and frequently this was of a 
character that materially influenced the intrinsic value of 
the two rows. Itseemed hardly possible to describe such as 
distinct, and quite improper to pronounce them synonyms. 
It has seemed best, therefore, to follow Vilmorin in recog- 
nizing sub-varieties or strains in some cases, permitting 
the strain to retain the name under which it has been gen- 
erally known. ‘This distinction has long been recognized 
by seedsmen, and probably could not be wisely ignored, 
because improvement must generally come through slow gra- 
dations, and to refuse to recognize such inc ipient varieties 
would be detrimental to progress. The names of such 
strains in the described list are printed in italics. 
CLASSIFICATION, 
As an aid in identifying varieties, we have adopted, with 
slight change, a classification proposed by M. Augustin P. 
De Candolle, a learned French botanist, in a paper read be- 
fore the London Horticultural Society, Aug. 7, 1821. This 
plan separates the heading cabbages into two principal 
classes, based upon the degree of blistering of the foliage, 
or in other words, upon the relative development of the 
parenchyma and veins. <A similar division has. long been 
recognized by horticultural writers and seedsmen, the 
smooth or less blistered sorts being known as cabbages, and 
the more blistered ones as Savoys or Savoy cabbages. M. 
DeCandolle inclines to consider these classes as distinct
