Scientific Name Sisyrinchium angustifolium Mill. Common Name pointed blue-eyed grass General Description Perennial herb; stems branched, 10-42 cm tall, broadly winged, dark olive green to bronze or blackish when dry, hairless Leaves Basal, simple, 10-30 cm long, 2-2.5 mm wide, linear, parallel venation, hairless Flowers

Inflorescence an umbel, 1-3 flowers; flowers radially symmetric, about 1 cm long, develop between 2 unequal bracts of spathe; tepals 6, distinct, 7.7-12.5 mm, elliptic to inversely lance-shaped, apex rounded with awn, pale blue to violet, rarely white, bases yellow; stamens 3, filaments fused; pistils 1, ovary inferior, similar in colour to foliage

Similar species: S. monatum Easily confused with S. angustifolium. To tell the two species apart, one must only look at the branching patterns of the plants. S. angustifolium has visible branching of its stems, while S. monatum has no branching occurring (Flora of North America). As well, both of these species, S. angustifolium and S. monatum, have very distinguishing colours when dry in comparison to other Irises. When dry, members of these species emit dark bronze to black vegetative features, something not seen in many other members of the family (Flora of North America).
