28860. Iris sibirica L.

 terete, fistulous, murh overtopping the loaves, simple or forked, bearing several 

 clusters of flowers; limb bright lilac blue; outer segments 1^ to 2 inches long, 

 with orbicular blade gradually narrowed to a slender claw, veined with bright 

 violet, whitish toward the claw; inner segments shorter, erect. The plants 

 form large compact clumps producing many long flowering stems from the 

 center. " (Bailey.) 



See Nos. 9104 and 13232 for previous introductions. 



Distribution. — Throughout central and southern Europe and eastward to 

 eastern Siberia. 



28861. Iris missouriensis Nutt. (?) 



28862. Iris chamaeiris olbiensis (Henon) Baker. 



Same as No. 28858 except "flowers are bright yellow." (Bailey.) 

 Distribution. — Northern Italy and southern France and eastward through 

 Dalmatia. 



28863. Iris orientalis Miller. 

 Variety gigantea. 



Distribution. — Asia Minor and Syria, and the island of Samoa. 



28864. Iris paradoxa Stev. 



"Plants dwarf; leaves linear; flowers large, outer segments reduced to a 

 mere claw, dark, covered with pile; inner segments 2 inches long, orbicular, 

 lilac to white. A flower with singular combinations of color. Grows in dry 

 situations, but requires shelter in winter." (Bailey.) 



Distribution. — Dry sandy places in the Transcaucasian region of southern 

 Russia and in northern Persia. 



28865. Iris prismatica Pursh (?). 



28866. Iris ruthenica Dryand. 



"Leaves 5 to 12 inches long, in crowded tufts; stem slender, 3 to 6 inches 

 long, but often obsolete; tube twice as long as the ovary; outer segments with 

 an oblong blade rather shorter than the claw, lilac, violet scented. Blooms in 

 April and May." (Bailey.) 



Distribution. — Eastern Europe and central Asia, extending from Austria 

 eastward through Russia and Siberia to eastern China and Mongolia. 



28867. Iris setosa Pall. (?) 



Distribution. — Eastern Siberia, Japan, and in northwestern North America. 



28868. Iris halophila sogdiana (Bunge) Skeels. 



(Iris sogdiana Bunge, Academic de St. Petersbourg, Memoires des 

 Savants Etrangers, vol. 7, p. 507, 1850-54.) 



(Iris gueldenstaedtiana sogdiana Baker, Irideae, p. 14, 1892.) 

 The name Iris gueldenstaedtiana was published by Lepechin (Acta Academiae 

 Petropolitaniae for 1781, pt. 1, p. 292, pi. 8) in 1784. But Pallas in 1773 (Reise 

 durch Verschiedene Provinzen des Russischen Reichs, vol. 2, p. 733) had pub- 

 lished the name Iris halophila for the same species. The earlier name should 

 be used for the species, which necessitates transferring the subspecies published 

 by Baker to /. halophila. 



Same as No. 28857 but "with gray-lilac flowers (Bailey)." 



Distribution. — Throughout Asia, from Asia Elinor and the Caucasus region 

 eastward to Kashmir and Mongolia.
