Observations.

This very imperfectly known Iris is in some ways intermediate between I. flavissima and I. Bloudowii, that is to say that it has the spathes of the former and the leaves and rhizome of the latter. All our knowledge of it is derived from dried specimens, and these seem to show that the spathes are more distinctly green than in either of the other two specimens.

It is probable that the branching stem of Komarov's specimen (K) is abnormal. A better knowledge of this Iris may show that it is hardly sufficiently distinct from one or other of the allied species.
