Tus Englith fpecific title to this plant, fhould feem to imply, that the flowers are fuch, as fhould not 
come into our arrangement; but, as the charaéter is not conftant in all the flowers, even on the fame 
plant, it cannot be confidered but as a {pecific charaéter in this particular fpecies, though the name has 
its proper force, in contradiftinétion to its congeners, in our language. It is a native of Mexico, South 
America; and was introduced to our gardens about the year 1789, by Mons’ Richard, from the Paris 
gardens, at the fame time with the Virgilia; a moft beautiful annual, of the habit of Arétotis, now — 
loft in both countries from the difficulty of procuring ripened feeds, It is to be raifed in the fame 
manner as the other fpecies, on a gentle hot-bed, in March, and planted out the beginning of May. 
The flowers make their appearance about the beginning of Auguft, and continue, in fucceffion, till they 
are deftroyed by the froft. To be certain of the feed, the heads muft be taken from the plant, whilft : 
they appear yet freth; as the petals are perfiftent, and have not the appearance of entire decay, though 
the feed is nearly ripe; for if the receptacle once begins to rot, (which it is very fubject to,) the feeds 
are immediately contaminated and fpoilt. Our figure was taken, this year, at the Hammerfmith Nur- 
fery, where, it was grown firft in this kingdom.
