Douglas in Edward's Botanical Register table 1218, (1829)Along with the Latin Diagnosis the following comments were made---A new species discovered by Mr. Douglas, to whom we are much indebted for the following memorandum concerning it:"A common plant in North California, and along the coast of New Georgia, in dry soils or open parts of woods; flowering in April and May.The native tribes about Aguilar river, in California find this plant very serviceable for many purposes the veins of the leaves fine cord is made which is converted into fishing nets; and from its buoyancy great strength, and durability, it suits this purpose admirably. It is also made into snares for deer and bears ; and a good idea may be formed of its strength, when a snare, not thicker than a 16-thread line, is sufficient to strangle Cervus Alces, the Great Stag of California, one of the most powerful animals of its tribe. The cordage is also manufactured into bags and other articles.From the foregoing account, and from what we have seen of the plant, we incline to think it might be profitably cultivated in waste land in this country for hemp. It is quite hardy, grows readily, and might soon be increased considerably; being a perennial, it would be cultivated at little expense, and there is no doubt that it would be far more advantageous to a British agriculturist than the celebrated New Zealand flax, of the success of which in this climate there is now, we presume, no probability.A plant forming close tufts of rigid, erect, linear-ensiform, evergreen, tough leaves, which in wild specimens are rather shorter than the flowers. Stem erect, a foot or rather more high, angular, leafy, clothed at the base with remains of the leaves, as in Allium Victorialis. Ovarium on a long stalk, not enclosed within the floral leaves, what 3-cornered. Flowers about the size of Iris virginica, sessile on the ovarium, dark purple, veiny; the outer petals obovate, acuminate, spreading, beardless ; the inner obovate, rounded, erect, shorter than the others. Stigmas 2-lobed, short. This species is most nearly related to the Iris humilis ot Bieberstein, from which, ruthenica, bidumis. and all the some neighbouring species, it is distinguished by the proportion borne to the outer petals by the stigmas, by the short tube of the corolla, and by the long stalk upon which the ovarium is elevated far above the floral leaves.Our drawing was made in the Garden of the Horticultural Society in November last. It is not, however, to be doubted that its true season of blossoming is the spring: the Garden specimens were in all respects like the wild except that the leaves were longer than the flowering stem circumstance probably caused by the period at which the plants came into flower --J.

Purdy in The Garden, p.1 Jan 1st. 1898I. TENAX, and flowered it splendidly the first season. It grows low in dense tufts usually in rather heavy land. The plants as they came to me were mixed with blue grass. The leaves were individually not over 4 inches long, although the finest herbarium specimens had leaves about 10 inches high. The one-flowered stem is 3 inches to 4 inches high, bearing a most charming little purple flower. I was delighted with it. Other plants from Central Oregon which may be the same, but the identification is imperfect, had flowers of a rich yellow, anti I was informed the colour varied from purple to pure white. |

Distribution: The distribution of the species gives clues as to its cultural requirements, although plants in cultivation can often tolerate a wider range of variables: The species is found in the following region:Bonap's North American Plant Atlas shows the following map reproduced by permission of Kartesz, J.T., The Biota of North America Program (BONAP). 2015.
