diftinguifhable from its Congeners by thé 
Glandules, that are fprinkled over the 
Corolla. 
Stipule are of great confequence in many _ 
extenfive Genera, where the Species are li- 
able to Confufion. Thus in one Species of 
Mel-anthus the Stzpule are folitary; inthe 
other they are in Pairs ; and the Caffa auri= 
culata is rendered diftin@ from all its Con- 
geners by the Shape of its St7pule, whichare 
reniform and barbate. 
HYBERNACLES afford likewife a cer= 
tain fpecific Difference. 
That Gems or Buds often differ greatly in 
the fame Genus is proved by Rhamanus; in 
which the various Species, viz. Cervi/pina, 
Vaternus, Paliurus, and Frangula, have all 
a Difference in their Buds; and in that ex- 
tenfive and intricate Genus the Salrx, the 
Species are by the Stru€ture and Foliation 
of the Buds diftinguifhed with great Cer- 
tainty. 
Bulbs alfo diftinguith the Species, as is 
proved by Scz//a, where they afford a real, 
and almoft the only DiftinGion; and by their 
Situation in the Axle of the Leaves, they 
determine Dextaria, Lilium, Ornithogalum, 
Saxifraga, and Bifforta.
