The Juno Section 
Diagnosis. 
I. bucharica Juno; /. orchioidi affinis sed folia latiora et breviora nec longe acuminata; segmenta 
exteriora, albo-lutea. 
Description. 
Rootstock , a bulb, similar to that of /. orchioides, but apt to be more globose. 
Leaves, 8 — 12 in. long by 2 — 2\ in. broad, bright green, deeply channelled towards the upper end, 
the upper surface glossy and the under glaucous, with a narrow white horny margin, bearing a number 
of inconspicuous setae. 
Stem, 12 — 18 inches high, bearing 5 — 7 flowers set in the axils of the leaves. 
Spathe valves, 3 in. long, projecting £ in. above the standards, of a paler green than in orchioides, 
slightly scarious at the tip and edge. The outer valve when unrolled is very wide, as much as in. 
across. 
Pedicel, practically none. 
Ovary, nearly £ in. rounded, trigonal. 
Tube, — 2 in. 
Falls, over 2 in. long, blade more than 1 in. broad. The pure white strap-shaped haft is separated 
by a slight constriction from the obovate or even orbicular blade of a bright golden colour, emarginate 
and bearing a large wavy golden crest, which is continued along the haft as an inconspicuous median 
ridge, faintly dotted with dark green. In some specimens dark purplish veins flank the crest as in 
orchioides, but in others these are entirely absent. 
Standards, small, pure white, depressed below the horizontal ; the short canaliculate haft expands 
into a broadly lanceolate, distinctly mucronate blade. 
Styles, pure white, very large and conspicuous, standing up well above the falls. 
Crests, large, and reflexed to an upright position, pure white, quadrate or obscurely deltoid. 
Stigma, conspicuous, white, semicircular in outline, but much narrower than the style. 
Filaments, colourless. 
Anthers, creamy white. 
Pollen, spherical, with hexagonal bosses. 
Capsule, cylindrical, 2^ in. long, with six sides arranged in three pairs. Walls thin and bulging, 
showing the outline of the seeds within. 
Seeds, numerous, deep buff or light reddish brown, irregularly cubical. See Plate XLVIII, Fig. 6. 
Observations. 
This is the strongest grower, and one of the most strikingly beautiful of all the Juno Irises. 
That it is prolific is proved by the fact that two bulbs planted in the autumn of 1906 gave 4 flower 
spikes in 1907, 7 in 1908. 13 in 1909, 21 in 1910, and over 40 in 1911. To obtain this result the 
bulbs were lifted every second year when the foliage turned yellow in July, and planted again in 
September in fairly rich soil, in a warm, well-drained position. 
Each stem bears 5 or 7 flowers, of which several are usually expanded at the same time and the 
contrast between the pure white of the styles and the golden yellow of the fall-blades, set among the 
glossy bright green leaves, is extremely pleasing. 
/. bucharica is obviously allied to /. orchioides, with which it agrees in possessing unwinged, strap- 
shape falls and cubical seeds, but from which it is distinguished by the broader, less gradually 
tapering leaves, which are more conspicuously striated on the under surface. The colour, too, is very 
different. The exact relationship of the two plants is, however, uncertain. 
Seed is produced in abundance and, if sown at once, germinates freely, but the seedlings take 
several years to arrive at flowering size.
