This appears to be the commonest Iris of the Rocky Mountains. I place the plant we have long known in England as Tolmieana as a synonym of Nuttall' s doubtful missouriensis, on the authority of Dr. Sereno AVatson,. who, in the recently-published " Botany of California," states its distribution as follows : — " On the eastern side of the Sierra Nevada from Inyo to Siskiyou county and the Columbia, common in the mountains of the interior eastward to Colorado and Montana, and south to Arizona ; apparently the only species of the Great Basin." Whether it be more than a montane variety of the Californian Iris longipetala of Herbert (Bot. Mag., Tab. 5298), which is a very much finer plant from a cultural point of view, I greatly doubt. Although long known, it has never been previously figured. Our drawing was made from a plant sent at the end of May from Mr. F. Horsman, of the New Plant and Bulb Company, Colchester..Descr. Rhizome short, creeping, with fleshy root-fibres. Produced leaves about four to a tuft, linear, not more than a foot long, firm in texture, a quarter or a third of an inch broad, narrowed gradually to the point. Stem overtopping the leaves, bearing a single terminal cluster of two or three flowers, fistular, subterete in the lower part, angled towards the top. Spathe-valves lanceolate, two or three inches long, membranous towards the tip. Peduncles nearly always shorter than the spathe-valves. Ovary cylindrico- trigonous, three-quarters of an inch or more long at the flowering time. Perianth-tube fundibuliform, not more than a quarter or a third of an inch long ; outer segments of the limb oblong-unguiculate, reflexing, two or two and a half inches long, veined with lilac-purple on a pale groundwork, and faintly keeled with yellow towards the base of the limb ; inner segments nearly as long as the outer, erect, oblanceolate, with a long claw, emarginate, plain lilac-purple. Stigmas an inch long, exclusive of the reflexing subquadrate strongly-toothed crests. Anthers as long as the filaments. Capsule oblong-trigonous, an inch or an inch and a half long, cuneate at the base and apex. — J. G. Baker.

|Dykes in The Genus Iris; 1913,This Iris, which sometimes occurs in gardens under the name of I. longipetala montana (see Lynch I.e.), scarcely needs a separate description. It differs only in being more slender in all its parts, in holding its flowers well above the leaves, and in losing its leaves entirely in late autumn, Its colour, the shape of its capsule, and the seeds are identical with those of I. longipetala. In both cases the perianth tube is short, of a pale yellow-green, and not perceptibly constricted above the ovary.Observations, see Dykes under Series Longipetalae,|
