rately defcribed by Mr. Curtis. Linnean characters of Euphor- 
bia defective. 142, Inveftigation of Euphorbia, on the Linnean 
principles, extremely difficult ; a diftinct idea may be attained 
of the Genus by the diffection of fome of the larger fpecies. 
The part, called by Linneus, the Corol, Mr. Curtis names the 
Nectary. Singular appendage of the Seeds of Euphorbia, 
taken notice of by Mr. Curtis. 143, Definition of the 
term Nectary. Honey profufe in the flowers of the A'r- 
butus Unedo; found at the bafe of the petals of Pa- 
pilionaceous flowers. Clover contains much honey. Chief

Fructification. 144, Nectary of Fritillaria, mod obvious in' 
the fpecies Imperialis, Crown-imperial. Different kinds of 
Nectary, Nectary, the term applied by Linneus, to every An- 
gularity of Fructification, which cannot be reduced under the 
feven regular parts of a flower. 145, Nectary, as a feparate 
appendage, not found in all flowers. All flowers believed, by 
Linneus, to contain honey. Nectaries diftinguifhed, by Lin- 
neus, into two kinds. The tube of the Florets of Compound 
Flowers contains honey. Nectary only noticed by Linneus 
when it characterizes a Genus. 146, The tube of One-petalled
