Observations.

The appearance of the rhizome of this Iris and of the many flowered spathes suggested that it is really a member of the Regelia group. This is confirmed by the capsule and by the seeds. The former is smaller than, but similar in shape to, those of the Regelia Irises and the seeds have the characteristic white aril (cf. herbarium specimens and Maximowicz's description in B. A. P. I.e. "hilo perforato albido ").
