Diagnosis. 
/. orchioides Juno; segmenta exteriora ungue oblongo nec alato, lamina ovata vel suborbiculare,

Description. 
Rootstock , a bulb as large as or even larger than a hen’s egg with long fleshy roots persistent 
in the dormant state. 
Leaves , 6 — 12 inches long by 2 wide, pointed, deeply channelled, with glossy upper surface and 
glaucous under surface ; the white margin is narrow and inconspicuous but bears a number of 
minute setae. 
Stem, about a foot high producing three or more solitary flowers in the axils of the leaves. 
Spathe valves , i| — 2 in. long, narrow, pale green, acuminate. 
Pedicel , very short. 
Ovary , rounded, trigonal, almost cylindrical. 
Tube , 1^ — 2 in. long, trigonal. 
Falls. The blade is ovate, emarginate, with a conspicuous crest, the haft a narrow oblong. In 
the type the colour is deep yellow ; two narrow greenish veins run parallel along the haft and form 
more or less distinct dark greenish blotches on either side of the crest. 
Standards, small, horizontal or drooping, lanceolate with a narrowly canaliculate haft, ^ — f in. long. 
Styles, keeled, rather broader than the haft of the falls. 
Crests, nearly triangular, with slightly indented outer edge. 
Stigma, large, almost semicircular. 
Filatnents, slightly longer than the anthers, yellowish. 
Anthers, yellowish, cream-coloured. 
Pollen , pale yellow, spherical with hexagonal bosses. 
Capsule, 2 — 2^ inches long, tapering towards either end, of a pale whitish fawn colour with 
thin papery walls through which the seeds bulge. 
Seeds, numerous, deep buff or light brown, irregularly cubical. 
Observations. 
When this plant was first discovered by Regel, it was looked upon as a large form of 
/. caucasica. It has proved however to belong to an entirely different section of the Juno Irises, 
for the falls are strap-shaped and the seeds cubical (see p. 188). It differs further from I. caucasica 
in having longer, more pointed and more sharply folded leaves. 
There are now in cultivation several forms of this Iris. They vary in the amount of olive- 
green veining or blotching that is apparent on the blade of the falls. Still more distinct are the 
varieties alba and sulphurea, which however only differ from the type in the colour of the flowers, 
and this is sufficiently indicated by the names. Both these varieties are at least as vigorous as, 
if not more vigorous than, the type and set seed as freely*. Unfortunately the seedlings that I have 
raised have not yet reached flowering size and I am unable to say whether the varieties will 
breed true. 
For cultivation see p. 187.
