From the last named species it is distinguished by its never having a three-flowered, though it varies with a one-flowered scape; by its peduncled, not subsessile  flowers; by the reflexed laciniae of the corolla not being narrower than the upright; and by the three-cornered, not rounded germen.</br></br>It is upon Dr. Fischer's authority that we give this as the Iris furcata of Marschall; for not having had an opportunity of examining the plant ourselves, we could not have decided whether to refer it to that species or to biflora. The second volume of the Centuria plantarum rariorum Rossicarum, if published, is not, we believe, as yet arrived in this country.</br></br>Native of Northern Caucasus, where it grows very common in the open pastures.

Register table 801, 1824<img src="%PUBURL%//Spec/SpecFurcata/FurcataEdwardsBotReg1824.jpg" style="margin: 10px; float: right; height: 400px;" />Our drawing of this pretty species of Iris was made at Messrs. Colvilles Nursery. It appears, upon the authority of Mr. von Bieberstein, to be the species which he, in his Flora Taurico-caucasica, referred to Iris biflora, from which plant he now has distinguished 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. </br></br>We perceive, however, that M. Link is of opinion, that I. furcata and I. biflora are not distinct; and that the Iris 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.</br></br>One of the flowers of this species is usually abortive. It is common in every open sward throughout the Caucasus.|
