This devoted lover of flowers carefully noticed the sensibility 
of plants, and composed a horologe of flowers. The list is 
given in his “ Philosophia Botanica,” which, however, is only 
valuable to us in giving the names of plants which’ open and 
close at stated periods, as the time given is for the meridian of 
Upsal. For the use of our friends we have given a list of 
twenty-four, extracted from that magnificent and useful work, 
the Encyclopedia of Gardening, by J. C. Loudon, Esq., and by 
observation of the following plants, also, the ingenious reader 
may be enabled to add to the number. Many species of con¬ 
volvulus and companula, the marvel of Peru, or belle-de-nuit, 
broom, tulips, cress, hibiscus, yellow lily, white water-lily, 
and dianthus.
