Iris basaltica is a species in the genus Iris, it is also in the subgenus of Iris and in the Oncocyclus section. It is a rhizomatous perennial, from the basalt deserts and hillsides of eastern Syria. It has many falcate long leaves, and long stem. Between March and April, it has white or pale green flowers covered in thick purple or black veining and dots or spots. It also has a purple or maroon beard, tipped with yellow. It is rare cultivated as an ornamental plant in temperate regions, due to its environmental conditions of its natural habitat.
Like other irises, it has 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals), known as the 'standards'. The falls are a darker shade of colour than the standards. They are ovate to lanceolate shaped, and 9 cm (4 in) long and 5 cm (2 in) wide. They have a rounded dark signal patch, which is 1.5 cm in diameter. In the middle of the falls, is a sparse, row of short hairs called the 'beard', which are brownish purple, or maroon or purple, tipped with dark yellow. The paler standards are orbicular (rounded), and 8.5–10.5 cm (3–4 in) long and 7–7.5 cm (3–3 in) wide. They also have scattered purple hairs on the claw, (part of the petal near the stem).
It has creamy white and 3 cm long anthers, and thick, 1.5 cm long filaments. It has style branches which are 8 cm (3 in) long, they have multiple maroon or purple spots. The ovary is 2.5 cm long and the perianth tube is 2.8 cm long.
As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings. It has a chromosome count: 2n=20, which was first counted by Marc Simonet in 1954, and then by Avishai & Zohary in 1977.
It was also published in (Publ. Am. Univ.) Beirut, Nat. Sc. Ser. No. 1; et No.3 in 1934, then in Gardening Illustrated (with a colour illustration) in Vol.57 on page 227 in 20 April 1935 and in the Journal of The Royal Horticultural Society Vol.60 on series 5 on page 221 in 1935.
Distribution and habitat
It was listed as in danger of extinction by SA Chaudhary, in 1975. It was then listed as 'Endangered' by IUCN in 1997. It was then listed as Data Deficient in 2016, due to the Syrian civil war.
Irises can generally be propagated by division, or by seed growing. Irises generally require a period of cold, then a period of warmth and heat, also they need some moisture. Some seeds need stratification, (the cold treatment), which can be carried out indoors or outdoors. Seedlings are generally potted on (or transplanted) when they have 3 leaves.
Hybrids and cultivars
One known cultivar is 'Basaltica'.
Like many other irises, most parts of the plant are poisonous (rhizome and leaves), and if mistakenly ingested can cause stomach pains and vomiting. Also, handling the plant may cause skin irritation or an allergic reaction.
