Description

It has 3 mm wide leaves, [4] which appear in the autumn. [5] It normally reaches a height of 10-16 inches (or 25–40 cm). [6] But can reach up to 45 cm tall. [5] It flowers between March and June. [6] Normally more than 2 flowers per stem. [7] When the flowering shoot comes out of the ground it is covered in a purple or white blotched sheath. [4] These then open up to revel red-purple flowers with orange spots, [6] or yellow stripe on the falls. [8]

Biochemistry

As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings. [6] It has a chromosome count: 2n=32. [8]

Taxonomy

Its name means 'thread-leaved iris'. [9]

In Gibraltar, it is also known as the 'Narrow-leaved Purple Iris'. [10]

It is often mistakenly called 'Spanish Iris'. [11] The Spanish Iris is Iris xiphium .

In 1842, it was first described by Pierre Edmond Boissier in 'Voyage botanique en Espagne' Vol 2, on page 602. [12] Dykes notes that this description is incorrect. [13] It was also described in Curtis's Botanical Magazine No.5929 as 'Xiphion filifolium'. [3]

It was recorded in the Catalogue of Life in 2011, [2] and it was verified by United States Department of Agriculture Agricultural Research Service on 4 April 2003, and updated on 14 November 2005. [14]

Distribution and habitat

It is native to temperate regions of North Africa and Europe. [14]

Range

It was found originally on Sierra de Mijas, [15] and Sierra Bermeja in Spain, at 3,000–4,000 ft (910–1,220 m) above sea level. [3]

It is found within Africa, in Morocco, (near Tangier, [6] [8] ) and within Europe, in Southwestern Spain, [14] [6] [8] and in Gibraltar. [10] [8]

Habitat

Iris filifolia likes to grow in sandy areas. [16]
