A very beautiful and sweet-scented spring flowering Iris, for which the Boyal Gardens are indebted to Mrs.Bodichon of Algiers. It has been referred by Alefeld to his genus Neubeckia, the characters of which, as given by Klatt in his revision of the order Iridete quoted above, seem to me of very doubtful generic value, depending mainly, if not altogether, on a very variable character — viz., the length of the tube of the perianth, " elongate " in Neubeckia, and " short," in Iris. A further diagnostic character is given to Neubeckia, in the persistent septum of the anthers, but this, if not accompanied by characters of higher importance, is not enough to found a genus upon. Klatt refers the I. longispatha of this work (Table 2528) doubtfully to this species; Ledebour, however (Flora Kossica, v. iv. p. 95), identifies the I. longispatha with /. biglumis, Vahl, a Dahurian and Siberian species, of a very different habit.
I. stylosa is a native of the hedges of Algeria, and is also found in Corfu and the Morea ; it was first published, without a specific name, in 1789, by Poiret, in his Voyage en Barbarie, v. ii. p. 96, and afterwards, first as I. stylosa, by Desfontaines in 1798, and then as I. unguicularis by Poiret, in 1799.
Descr. Rhizome creeping, as thick as the thumb, pale, and with pale brown membranous sheaths. Leaves one to one and a half foot long, one-sixth to one-third of an inch broad, erect, slender, flat, thin, striated, attenuated to long sharp points, bright green, shorter or longer than the scapes. Scape erect, slender, sheathed by slender appressed spathes, one-flowered. Ovary narrow, slender, one inch or more long. Floioers sweet-scented, two to two and a half inches diameter. Claws of the perianth segments yellowish, veined with red-purple, one and a half inch long, gradually dilating into broadly oblong spathulate, subequal, entire, obtuse, unbearded laminae ; outer leaflets recurved, pale violet, mottled below the middle with pale yellow, and with a strong deep yellow central band ; inner rounded at the top, apiculate, of a uniform pale violet colour. Stigmas deeply cleft into linear lobes which are acutely 2-fid at the apex, and usually single toothed on the outer margin. — J. D. H.
