(3A): "l.. timofejewii was found to have as sharply distinct a karyotype as it does a phenotype; it should therefore prove a source of valuable riew genes to use in producing new sorts of dwarf hybrids." Russian friend to EB: "Iris timofejewii is the rarest species from N. Caucasus. This species loves a loamy rock slope with calcium. Its stem usually has two violet-purple flowers."

Blazek says that the plants in Rodionenko's herbarium had curious thick roots resembling those of the oncocyclus, but that plants in the garden were less conspicuous in this respect. Cook: plant from PC, described in Hobbs' Garden by NC: "7 in high, cupped and closed S of dark blue or light violet with a greenish brown base. Tucked F violet or dark blue. Haft marks gently faded out. Style arms and crests light violet,. beard white tinged light blue, long leaves partly falcate, 2 buds. A larger and bluer type than in MIS 5: 25. " Randolph R-13D: NC: "The styles and crests protrude out from the standards in a way similar to the aril species I. susiana. Its most unusual feature is its sickle-shaped foliage, a grayish blue-green. Each leaf has a narrow edging of grayish white. One spathe sharply keeled; the other scarious-papery. "ERo: "Wine-purple self, narrow at haft, very few haftmarks, lavender beard, blue-green foliage, falcate early in season, straight later, very stiff and wiry, narrow. Standards partly open, semi-flaring falls, 2-in stem, 5 in to tips of S, 2 buds, one spathe keeled, one scarious-papery, fertile pollen forming pods on both diploids and tetraploids."
