68 AN INTRODUCTION 
The Luxuriancy of the Ca/yx, mentioned 
in the beginning of this Chapter, is very 
infrequent, but not without Inftances ; in 
Dianthus Caryophyllus there is a Variety, in 
which the Sgvame, Scales, of the Calyx are 
fo multiplied as to conftitute a perfect Spike 
ina manner moft fimgular : The Gramina, 
Graffes, of the Alps, become full by their 
Gluma, Hu/xs, fhooting out into Leaves, as 
ina Species of the Fefuca; and in Salix 
rofia, and Plantago rofea, the Squama of 
the Amentum of the former, andthe Brac- 
tex * of the Spike in the latter will fhoot 
into Leaves alfo. 
Linnaeus has enumerated fome Tribes of 
Plants, which are not found fubje& to Luxu- 
riancy; but as the Heads, under which he 
has ranged them, are taken from the Syf- 
tems of preceding Writers, and not from 
the Sexual, it would perplex the Reader to 
explain them ; and we fhall therefore omit 
them: The Curious may have Recourfe to 
them in the Philofiphia Botanica, Page 81.
