Rootstock , as in I. germanica.
Leaves , as in I. germanica, but longer; distinctly narrow for so large a plant.
Stem , 2 ft. or more in height, bearing about six or eight or more flowers in a terminal head of two flowers, and three lateral shoots with 1-2 flowers. The buds are of a long, pointed oval shape.
Spathe valves flushed with purple, scarious only at the top, not so divergent as in I. Biliotti, 2 1/2-3 in. long, narrow.
Pedicel , short.
Ovary , 3/4 in. long, rounded trigonal with six very shallow grooves.
Tube , about as long as the ovary, green with purple stripes.
Falls ; under surface, spotted on the haft, as in Biliotti, but with the spots more conspicuous along the median line than at the edges. Upper surface, obovate cuneate, of a bright red purple, the haft bearing numerous thin chestnut veins on a whitish ground. The beard is in front white tipped with yellow but becomes wholly yellow at the base.
Standards , the obovate pale blue blade narrows somewhat sharply to the short canaliculate haft, which is faintly veined with brown purple.
Styles , short and broad of a pale purplish colour with more deeply coloured keel.
Crests , pointed triangular, with serrated outer edge, purple with blue veins.
Stigma , entire, rounded.
Filaments , white.
Anthers , very long, cream.
Pollen , cream.
Capsule of a long ellipsoid shape with inconspicuous grooves on each side, very bluntly trigonal.
Seeds , wedge-shaped, light brownish, much resembling those of I. pallida.
By an oversight due apparently to the fact that the original description of the species contained no express mention of the beard I. trojana was placed by Baker (Hdk. p. 18) among the Apogons. Struck by the description as being obviously that of a Pogoniris, I applied to the Vienna Botanic Garden and was most kindly supplied by the Director with a number of plants. When these arrived, it was at once obvious that I. trojana was a Pogoniris. The flowers proved to agree exactly with the original description. This fine sweet-scented Iris is fairly common in gardens under the mistaken name of I. cypriana, which is a much rarer plant. I. trojana is easily distinguished by the long, narrow, purple-flushed buds and by the broader foliage. Cultivation is easy.
