Our drawing of this pretty species of Iris was made at 
Messrs. Colvill’s Nursery. 
It appears, upon the authority of Mr. von Bieberstein, 
to be the species which he, in his Fora Taurico-caucasica, 
referred to Iris biflora, from which plant he now has dis- 
tinguished it by its scape never being three-flowered ; its 
flowers being stalked not sessile; its petals deflexed, not 
erect, and narrower than in I. biflora; and by its ovarium 
being three-cornered, not rounded. ke 
We perceive, however, that M. Link is of opinion, that 
I. furcata and I. biflora are not distinct; and that the 
Tris bohemica of Schmidt is referable to I. biflora also. But 
we know that in Dr. Fischer's opinion, I. furcata is distinct 
from I. biflora. 
One of the flowers of this species is usually abortive. It 
is common in eyery open sward throughout the Caucasus. ,
