The vegetable SYSTEM. 
bers which compofe this hitherto perplexed clafs, may be reduced to 
method, under the greater divifions firfl of ‘Tribes and Orders ; and 
then to certain Genera : knowing thefe, all the difficulties will vaniffi : 
for whofoever will examine the objecfls with due care, will find, in th’s, 
as in all other inftances, that thefe deplor’d perplexities have their foun- 
dation in art only ; not in Nature. 
C- L A S S I. 
The Aflbciates may be diftindtly arranged under two general Tribes. 
TRIBE I. 
Thofe which have the Scales of the Cup formed by a degradation of the 
Leaves. 
TRIBE II. . 
Thofe which have the Scales of the Cup, original, and altogether di- 
ftindt. 
ASSOCIATES. 
TRIBE I. 
With DEGRADATING SCALES. 
ORDER I. 
In which the degradating Leaves form Scales 07 ilyy as in Safi-flower. 
Plate 1 . Fig. g. 
ORDER II. 
In which the lower range of degradating Leaves becomes Jihnyy as in 
Blefi'ed Thiftle. 
Plate I. Fig. 10. 
ORDER III. 
In which the upper Range of degradating Leaves becomes nie?nhranaceous, 
as in Carline Thiftle. 
Plate I. Fig. II. 
ASSOCIATES. 
TRIBE II. 
With Original and distinct Scales. 
The Aftbeiates of this Tribe which are very numerous, admit an in- 
termediate diftindtion, into three feparate Families, according to the 
Nature of their Scales; before we defeend to the Subdivifion into Or- 
ders.
