(SPEC) Iris Duthieii Foster

1887, Foster

Iris duthieii (Sir Michael Foster, 1887) Now relegated to a synonym of Iris Kemaonensis Originally described in "Some New Irises", The Gardeners' Chronicle I. p.611.

Foster provided the following:

SOME NEW IRISES.
In the following lines I desire to describe provisionally some new Irises which flowered with me during the past summer, I say "provisionally," because experience has taught me that the features exhibited by a plant during one year's flowering — especially when that flowering is the first flowering after introduction from a distant land — are not always to be trusted as telling a true tale, or the whole tale. And while I feel confident that I have seen enough to justify me in considering the plants which I am about to describe as new species, and, as such, worthy of being made known and named, I should wish to defer the formal description of them until my experience of them is larger. I have, therefore, on this occasion given no Latin diagnoses.

I. DUTHIEII, sp. n.
Rhizome knotty rather than fleshy, the old part bearing scattered tufts of fibres, the remains of old leaves, the new part consisting of clusters of elongate oval buds, sheathed with remains of leaves partly splitting into fibres, and bearing new young buds at their bases.

Flower solitary, sessile, appearing before the leaves are mature. Leaves when fully developed, long and narrow, about 2 feet by 1/2 inch, yellowish green in color, five or six to a tuft.

Spathe-valves two, about 1 1/2 inch by 1/2 inch, pale green, veined, pointed, keeled, and somewhat ventricose.

Falls spreading almost horizontally, at all events not markedly reflexed, lanceolate, with the claw gradually expanding into the lamina; upper surface of claw white with thick purple red-lilac veins, the lamina of more uniform red-lilac marked with deeper coloured veins and blotches; under surface greenish-yellow, with veins and blotches shining through. On the claw extending on to the lamina is a distinct compact beard of discrete hairs, which are white over the lamina, but are tipped with yellowish brown colour over claw.

Standards about 1 1/4 inch long, connivent, oblong-ovate, the lamina of a red-lilac, paler than the falls, marked with deeper veins

Styles light red-lilac, rather deeper in colour in the median region; crests triangular, with crenate edge.

Tube 3 inches or more in length, green, with purple stripes.

Ovary not seen

Capsule 1 1/4 by 1 inch, trigonal, dehiscing along the sides; seeds oval, reddish-brown, wrinkled, with a distinct arillode or strophiole,

Found by Mr. Duthie in Katti Gangti valley in Byans. Northeast Kumaon (See Gardeners' Chronicle March 20, 1886, p. 372'

Flowered in England May 14, while the leaves were as yet only 2 or 3 inches long, the full development of the foliage not taking place until midsummer.

I desire to name this Iris after Mr. Duthie, F.L.S., the able Superintendent of the Botanic Gardens, Saharunpore, to whom I am indebted for the roots.
