This plant was sent to the Horticultural Society by 
Captain Munro, as a species of Fagopyrum from Chinese 
Tartary. It is certainly the plant strangely called Poly- 
gonum cymosum by Treviranus, for it has no cymes. It 
would have been better to have taken Lehmann's name of 
acutatum, but we are unwilling to disturb the existing termi- 
nology. 
It is a hardy perennial of the easiest culture, growing 
freely in any common garden soil, and increased either by 
seeds or dividing the roots. It flowers the first season from 
seed, and is well worth cultivating as an annual, for it blooms 
freely from July to September, and grows from 1 to 14 foot
