General Description:

Bloom resembles a reticulata iris, extremely short, and with leaves appearing after bloom. Flowers are violet-purple with white spots. (D. Kramb, 06-SEP-04)

The flower sits at soil level on a short tube 1cm long. Flowers are approx 2cm across. The overall color is a rich violet-purple, with the falls heavily blotched with white. There is no beard, but barely a hint of a raised central ridge on the falls (in yellow). Foliage is poorly developed at flowering time although 2-3 sheathing leaves (prophylls) appear alongside the flower. Flower-bracts and sheathing leaves are pale green, slightly scarious, with a distinct dark purplish line along the keel, and sometimes another parallel line each side of this. After flowering one or two true leaves appear on a short stem up to 5cm long. These are narrow, erect or curving, and markedly pleated, up to 1cm wide and 30cm long by mid-summer. The rootstock consists of a tiny conical growing point with a tuft of the previous year's persistent leaf bases, and 1-3 small pale cylindrical tubers, up to 12mm long, as well as a few thin fibrous roots. The seeds from immature pods were observed to have a small aril. (D. Kramb, 06-SEP-04)
