■ (SPEC) Iris biglumis Sweet (variation of Iris lactea Pallas)
, 1835, Siberia), Sweet provides the following: "Root creeping. Scape round, about 3 inches high, entirely enclosed by a pair of leaves, from the bosom of which it issues. Leaves narrow, ensiform, acuminate, erect, rather stiff, and harsh to the touch, of a dull glaucous green, dark red at the base, exceeding the scape, and lengthening considerably after the flowering season. Spathe composed of two broad, ovate-oblong, acute, membranous, green, adpressed, nearly equal leaves; their edges scariose, and overlapping each other towards the base. Flowers mostly 2, sessile, of a pale blue; the segments about equal in size and form, narrow, rather spathulate than lanceolate; the outer 3 reflexed, rathger broader and paler than the inner ones, which are erect, but hardly connivent; the disk of whitish colour, marked with numerous purple veins and spots. Stigmas linear, cloven, deeply and sharply serrated, of a deeper shade of blue. Ovarium about an inch long, marked with 6 furrows; the alternate ones rather deeper.
Very nearly related to I. spuria
, but apparently distinct from all the varieties of that species by its shorter stem, broader and glumaceous bracts, and nearly equal segments of its flowers. A native of Siberia, where it was discovered by the celebrated Pallas
, who has given a figure and description of the plant in his valuable travels. Our figure will be found to differ in some respects from his; but we have no doubt of the identity of the two plants."--Sweet, The British Flower Garden 2nd Ser. 2: tab. 187. 1833, illustrated; synonym. Iris ensata
