lliut, that thofe, who have opportunity and inclina- 
tion, may gratify themfelves, and probably at the 
fame time extend this branch of botanic knowlese 
ftill farther. 
It is proper to obferve, that as thefe obfervations 
were made by Linnasus in the academical garden at 
Upfal, whoever repeats them in this country will 
very probably find, that the difference of climate will 
occafion a variation in point of time : at lead; this 
will obtain in fome fpecies, as our own obfervations 
have taught us ; in others the. time has correfponded 
very exactly with the account he has given us. 
Whether this faculty hath any connexion with 
the great article of fecundation in the oeconomy of 
flowers, I cannot determine : in the mean time it is 
not improbable. Future and repeated obfervations, 
and well-adapted experiments, will tend to illuftrate 
this matter, and it may be lead the way to a full ex- 
planation of the caufe.

plant open about eight o’clock in the morning, and 
never dole till paft noon. This plant is common in 
kitchen-gardens and in corn-fields, and flowers in 
June, and continues in flower three months.
