The Regelia Section 
125 
Filaments, purple. 
Anthers, greenish edged with purple, usually much longer than the filament 
Pollen, greenish. 
Capsule, pointed trigonal, walls thin with brown reticulations, dehisces below the apex like /. Bloudowii 
and the Oncocyclus species (Fig. 13, p. 124). 
Seeds, large, dark reddish brown, almost black, the large nearly pure white aril being very conspicuous. 
Observations. 
The colouring of this fine Iris varies considerably and, as some forms have received distinctive names, 
it may be as well to quote here those which were given by Foster in the Gard. Chron. July 11, 1888, 
P- 3 6 - 
Var. Leichtliniana, Garden, Nov. 7, 1885. The standards and falls are nearly pure creamy-white, 
with fine unobtrusive veins, and the “ signal " is of the deepest, almost black, purple. 
Var. venosa, Gartenflora, t. 1358, sub nom. var. venosa pulcherrima (Foster in a MS. note wished 
to change this name to nervosa), is a variety with much more conspicuous veining. 
Var. violacea. The olive green or brown of the type is replaced by violet or puce. 
Var. concolor, *Bot. Mag. 7025 B, was received by Foster from Eastern Bokhara, and is rather 
smaller than the type, the spathe valves being broader and shorter, more keeled and flushed with purple. 
The segments are relatively broader and shorter, the venation being almost wholly obscured by a general 
violet or purple colour. 
Of late years many seedlings of this species have been raised and endless forms have arisen, some 
of which are intermediate between the above-mentioned. It is impossible to name every variety, although 
all are so different from any other species, that it is difficult to mistake a specimen of /. Korolkowi for 
anything else. 
When the new growths first pierce the ground in late autumn or winter, some are green and some 
very deeply flushed with purple. I have so far been unable to connect this character with any others 
in the flowers. It is obviously parallel to the purple colouration at the base of the leaves of many 
Pogoniris, of which no satisfactory explanation has yet been given.

Diagnosis. 
I. stolonifera Regelia; I. Korolkowi affinis sed rhizoma valde stolonifera (see Plate XLVII, Fig. 2); 
segmenta omnia medio violacea, margine undata, cupreo-suffusa, exteriora cuneato-obovata, interiora 
copiose barbata. 
Description. 
Rootstock, a somewhat slender fleshy red-skinned rhizome, with a tendency to send out new stolon- 
like growths (see Plate XLVII, Fig. 2). 
Leaves, ensiform, somewhat dark bluish green, purple at base when young, coarsely striated. 
Stem, 1—2 ft., wholly concealed except at the summit by clasping leaves, bearing a single head of 
1 — 3 flowers. 
Spathe valves, green, navicular, sharply keeled, slightly scarious at the upper edge and flushed with 
purple, 2 1 in. long. 
Pedicel, very short. 
Ovary, 1 in., rounded trigonal, with a groove on either face, bright pale green. 
Tube, 1 in., funnel-shaped, green with a purplish tinge.
