We now proceed to the Neflary, which 
has been defined by Linneus to be that part 
of the corol which contains the honey, hav- 
ing a wonderful variety both as to fhape and 
fituation, fometimes being united with the 
petals, and fometimes feparated from them. 
The lower part, or tube, of one-petalled 
corols, generally is found to contain a fweet 
juice, which is the honey. In the flowers 
of arbutus unedo (lira wberry -tree) it is lb 
profufe as to run out, when the corol is 
opened, and to give the flowers a ftrong 
fcent, refembling that of the honey of bees ;. 
it is alfo found at the bafe of the petals, in 
many of the butterfly tribe of plants. Clover 
(trifolium pratenfe) contains much of this 
liquid. The chief diftinclions of the ne£la~ 
ries, which adhere to any of the parts of 
fructification, are, jirjl^ the fpur-form, which 
is found in one-petalled flowers, as map- 
dragon (antirrhinum), and valerian (Vale- 
riana) ; and in many-petalled flowers, as in 
orchis, lark-fpur (delphinium), and viola.
