I need not tell you that the word Synge- 
nefia is derived from 2uv, fimul> and revfo-/?, 
generatio^ and that it is the i9th clafs; a par- 
ticular explanation of which you will alfo 
find in the book lad mentioned. 
Having now ftript off all the florets, 
white and yellow, there remains, in your 
hand, a naked conical receptaculum-, feeds 
without pappus i calyx hemifpherical, com- 
pofed of uniform fcales; feeds obovate. 
Thefe peculiarities determine the genus. 
The Species is diftinguifhed by the ftalk 
being naked, fcapo nudo. 
If Chaucer, in the lines above quoted, 
alluded to this our common Daify, probably 
he was miftaken in the French name, which 
is Paquerete. The plant which the French 
call Margarite is the Chryfanthetnum leucan- 
thetnum, or Ox-eye Daify; eafily diftinguifh- 
ed from the former by its fize, the leaves on 
the ftalk, &c. 
From this fpecimen, I conceive, you have 
acquired botanical knowledge fufficient to 
{liftinguifti the plants of the Clafs and Or- 
der, Syngenejia, poly garni a fuperfua t wherefo- 
ever you may find them. Let us now ex- 
amine one of thofe yellow ftar-like flowers 
which grow in fuch abundance in this field.
