16. X. Stocksii, Baker. – Bulb above an inch thick, with . I tuft of fleshy cylindrical basal fibres and copious brown membranous coats, produced up its neck. Stem not more than 2 or 3 inches high, bearing 3–5 falcate leaves, and I – 3 one-flowered spathes. Leaves lanceolate, superposed, clasping the stem at the base, where they are 1/2 – 3/4 inch broad, half a foot long, firm in texture, narrowed gradually to a long point, distinctly ribbed and furnished with a distinct pale horny border. Spathes ventricose, 2 inches long, formed of two greenish acute lanceolate valves. Ovary sessile in the spathe; tube 1 1/2 inch long, not exserted from the spathe; limb pale yellow, 1 1/2 inch deep; falls obovate, with a broad cuneate claw twice as long as the reflexing limb; inner segments oblanceolate, unguiculate, 1/2 inch long, spreading horizontally, with a long claw, and a small rhomboid-cuspidate blade. Anthers 1/2 inch long, equalling the filaments. Capsule narrow oblong, 15-13 lines long, clasped tightly by the relics of the spathe.

A native of dry shingly hills on the borders of Afghanistan and Beloochislan, particularly the Chebel Tun, near Quettah, where it grows at an elevation of from 5000 to 10,000 feet, and was gathered by Stocks and Griffith. It comes very near X. caucasicum, but has a short produced stem and longer leaves, spathe-valves and capsules. It has never been introduced into cultivation. Dr. Stocks' specimens, in most of which the tlowers are faded, were gathered in May.
Mottet, Revue Horticole 75: 413. 16 Sep. 1903;
Dykes, The Genus Iris 201. 1913.

Rootstock , a slender bulb of the ordinary Juno character.
Leaves , 6 in., acuminate, falcate, ¼ in. wide, with distinct white edge.
Stem , short, producing about three flowers.
Spathes , one-flowered, 1¼-2 in. long.
Pedicel ,
Ovary ,
Tube , 1-1¼ in. long.
Falls . The oblong blade is shorter than the broadly winged haft. The colour appears to be lilac or light purple, but this is uncertain.
Standards , ¼-1¼ in. long, the narrow haft broadens into an obovate blade to which a long narrow point is attached.
Styles ,
Crests ,
Filaments ,
Anthers ,
Pollen ,
Capsule , I¼ in., long, narrow, trigonal.
Seeds , pyriform, without any conspicuous strophiole, small, light red-brown, wrinkled (Foster MS. description of seeds collected at Quetta by Duthie).

This Iris, which has never apparently been brought into cultivation, must be very nearly allied to I. caucasica. Indeed, it is difficult to see how it differs from that species, if we leave the uncertain colour out of the question. There is no record that Foster succeeded in raising any plants from the seeds that Duthie sent him from Quetta (MS.).
