''Iris benacensis'' is a species in the genus ''Iris'', it is also in the subgenus of Iris. It is a rhizomatous perennial, from Italy. It has similar sized leaves and stem, and blue-purple shaded flowers, that have a white, blue and yellow beard. It was once classified as a synonym of ''Iris aphylla'', before being re-classified as a species in its own right, although some sources still call it a synonym. It is cultivated as an ornamental plant in temperate regions. ==Description== It is similar in form to ''Iris aphylla'', but differs in flower form. It has stout and creeping rhizomes.〔 Richard Lynch 〕 The leaves can grow up to less than long.〔 It has a slender stem, that can grow up to tall, the stem is just longer than the leaves.〔 The stem has lanceolate spathes (leaves of the flower bud), that are tinted with purple.〔 They have (scarious) membranous tips, when the plants are in flower.〔 The stems hold terminal (top of stem) flowers, blooming early season,〔 between May and June.〔(【引用サイトリンク】url=http://luirig.altervista.org/flora/taxa/index1.php?scientific-name=iris+benacensis )〕 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'.
