Lately introduced from Chili, where it is native. 
Drawn at the gardens of the Horticultural Society, in 
which it had been raised from imported seed. 
The species was originally observed by the léarned and 
ingenious Chevalier de Lamarck. 
If incautiously handled, the plant inflicts a very smart 
sting, like the rest of the genus; from which circumstance 
the species have all acquired the name of Ortiga (Nettle) 
among the Spanish colonists.
