Commercial Availability:
The record is further confused by book and magazine articles using the name macrosiphon ("large" + "tube") for misidentified plants of other long-tube species, especially I. fernaldii and I. tenuissima. And sometimes true macrosiphon is found labled with some other name, like "Iris hartwegii". In I. macrosiphon, the ovary is almost always well hidden inside the two spathes, and the petals and sepals divide close along the rim of a bowl-like swelling at the top of the floral tube. (D. Kramb, 05-JAN-04)
