1831, Botanical author Carl Anton Meyer
Iris acutiloba Mey. (
Carl Anton Meyer, 1831, Transcaucasia); Dwarf,
Section Oncocyclus, height 6-12" (15-30 cm);
Although we have followed Mathew and included
lineolata as a subspecies of
acutiloba many botanists in Russia and Turkey would still argue that these are separate species. It is said that
lineolata is more rhizomatous and typical
acutiloba more clump forming. There is also a disjunct in distribution with
lineolata an Iranian plant and
acutiloba occuring in the Transcaucasus North of the River Kura. Also the typical
acutiloba Has two blotches one in the center of the fall and one near the tip of each fall. This form was named
bimaculata. Single blotch specimens are also said to exist but it is unclear that these are separate from
lineolata.

Variations
Classification Iris acutiloba Mey
Several color forms of
lineolata exist with creamy or yellow markings but the usual forms are with creamy white ground color but more or less heavily veined purple-brown; Falls usually reflexed especially in typical
acutiloba, but in some forms, especially
lineolata, they are spreading horizontally, with a conspicuous reddish brown spot for a signal area at the entrance to the pollen tunnel formed by the style arms. The beard of short brownish hairs; Standards larger than falls and pointed, Style greenish dotted brown; filaments and anthers green. From the specimens I have seen subspecies
acutiloba is a smaller plant, whereas
lineolata is larger. Both seem rather easy to grow in pots in an alpine house, following typical Oncocyclus culture. The color variations are very interesting and one could make an interesting collection of these plants. Since they grow in more mountainous areas, they are much cold hardier than some of the Israel-Palestinian Oncocyclus. ---Robert Pries
