Observations. 
The true plant, as first described by Baker and Foster in the Gard. Chron. 1888, 11. p. 182, is 
now very rare in cultivation. It appears, indeed, to be almost, if not quite, unknown in England, though 
I had the good fortune to find it last year in a garden in the south of France. Except that the 
stem needs some support to enable it to bear the weight of the huge flowers, it is one of the most 
decorative of all Irises. The flowers are of large dimensions and in the original plants were of a 
distinctly reddish-purple or lilac. 
An unfortunate confusion has arisen owing to the fact that some plants were sent to Foster as /. 
Junonia in 1903 or 1904, which were only a blue-purple flowered form of /. cypriana and not true /. 
Junonia (see p. 174). Foster thereupon proposed to call his original /. cypriana I. Junonia var. cypriana 
owing to the priority of Kotschy's name. (Cf. Gard. Chron. for July 1st, 1905.) 
Our knowledge of the plant is still very inadequate, and its true relation to such allies as I. trojana, 
I. mesopotamica and I. Junonia cannot at present be defined. The difficulty of working out the rela- 
tionships of these plants lies in the fact that they need a warm climate and a heavy dry limestone 
soil, if they are to flower well and set seeds. 
Moreover, they often suffer by reason of their habit of beginning to grow in the autumn, only to 
have the growths battered and broken, if not destroyed, by rough weather in the winter. The plants 
are then too feeble to flower in spring. 
VI. The Oriental Pogoniris. 
The three species of this group are characterised by spathes of a curiously membranous, almost 
transparent texture. By this feature they are easily distinguishable from the forms of I. germaniea 
which are probably only found in Central Asia as escapes from cultivation. See p. 155. 
(1) Stem unbranched; leaves very glaucous. /. scariosa. 
(2) Stem branched ; spathes broad and much inflated ; the outer leaves of each 
tuft very blunt and round. I. imbricata. 
(3) Stem taller with longer branches ; spathes narrow and less inflated ; falls 
with conspicuous veins that end abruptly at a straight line across the 
blade near the end of the beard. /. Alberti.

[N.B. Falk’s I. biflora, Beitrage II. p. 101, no. 59 (1786), which came from the Kalmuck and Kirgish 
Steppes near the Volga and Ural rivers, is probably I. scariosa and not I. aphylla, for that 
river seems to form the dividing line between the two species. Since however the determination 
is uncertain, it seems best not to restore the name.] 
Distribution. The typical plant is found near the Caspian, and in the Altai region ; I . Eulefeldii from 
Turkestan is apparently only a robust form.
