There are many fine garden forms having various shades of lavender, violet, blue, and white. {Bot. Mag. t. 2435.) I. nepalensis (/. decora).—A dis- tinct Iris, 6 to 12 ins. high, native of Nepaul. Rhizomes small, covered by a net of fibres, and having white fleshy, thong-like roots, and linear sword - shaped, tapering, striped leaves. Flowers of a delicate pale lavender, the lanceolate spoon-shaped falls having a median ridge of yellow hairs towards the base. The flowers are very fleeting, opening in the morning and fading before evening. The variety Letha, from the Chin Hills in Upper Burmah, is a better garden plant. It has deliciously fragrant flowers of a delicate lavender colour. It is now known as /. Golletti, and is figured in the Bot. Mag. t. 7889. {Bot. Beg. t. 878.) It is better to treat this Iris as recommended for the Oncocyclus group (see p. 292). I. obtuslfoUa.—A Persian species, with short oblong, bluntish leaves, and yellow flowers with striped falls and a bearded crest {Bot. Mag. t. 7701). I. oehro-aurea.—This seems to be a hybrid between I. oehroletMa and /. aurea. The rich yellow beardless falls are edged with creamy-white, and the standards are erect and bUobed. {Gard. Chron. 1900, xxviii. 32.) I. orchioldes {Orchid Iris).—A dis- tinct bulbous Iris found wild in Western Turkestan and Bokhara, remarkable for having bulbs some- times as large as a goose's egg. The flowers, 2 to 3 ins. across, are borne in March and April all along the stems, \\ to 2 ft. high. They are of a rich yellow, with or without a greenish tint or
