63483 to 66466. Iris spp. Iridaceae. 



66463. Iris bulleyana Dykes. 



Hollowstem iris. 



An iris from western China which, as 

 described by Dykes (The Genus Iris. p. 30), 

 resembles Iris clarkei, having a hollow un- 

 branched stem. The narrow leaves are 

 glossy above and glaucous beneath. Thr 

 stem, 15 to 18 inches long, bears a single head 

 of one to two flowers. The falls have a 

 greenish-yellow oblong haft, veined and 

 dotted with purple. On the obovate blade 

 the coloring becomes clearer and consists of 

 broken veins and blotches of bright blue- 

 purple on a creamy ground. The extremity 

 is a uniform blue-purple, paler at the edges. 

 The oblanceolate, channeled standards are 

 pale blue-purple with deeper veins and 

 diverge at an angle of about 60°. The keeled, 

 dark-purple styles are held high above the 

 falls.

66464. IEBS clarkei Baker. 



Clarke iris. 



"A curiously local species native to a 

 circumscribed area in the Sikkimand Bhutan 

 region at a height of 6,000 to 11.000 feet in 

 ground that is swampy half the year and hard 

 frozen under snow during most of the remain- 

 ing months. The narrow leaves, 2 feet long, 

 droop at the tops; the upper surface is pol- 

 ished and shiny, the underside glaucescent. 

 The solid srem is 2 feet long and bears one or 

 two lateral heads. The falls are hlue-purple, 

 blotched with white, and are reflexed later- 

 ally. The upper part of the haft is marked 

 with yellow. The reddish purple, lanceolate 

 standards are poised almost horizontally. 

 The styles form the highest point of the 

 flower; they are keeled, very convex, and 

 l l A inches long." (Dykes, The Genus Iris, 

 p. 29.) 



For previous introduction see No. 53704. 

 66465. Iris forresth Dykes. Yunnan iris. 



"A most pleasing iris, like a dwarf Iris 

 wilsoni, from which it differs in the less glau- 

 cous leaves, clearer yellow, unveined stand- 

 ards. The stem, 12 to 18 inches high, bears a 

 single head of two flowers, although a lateral 

 flowered branch sometimes develops. The 

 short haft bears two central lines and broken 

 lateral veins of brown-purple on a clear yellow 

 ground. The oblong, ovate blade of the falls 

 is often very long and drooping, of a clear, 

 lemon yellow which becomes deeper around 

 the end of the style branches and is there 

 marked with brown-purple veins. The 

 oblanceolate yellow blade of the standards 

 narrows to a deeply channeled haft, yellow, 

 shorter than the falls, and slightly divergent. 

 The broad, short-keeled, deep-yellow styles, 

 often discolored with purple, curve down onto 

 the falls. Native to open mountain pastures 

 on the eastern flank of the Likiang Ranee in 

 northwestern Yunnan, China, at an altitude 

 of 12,000 to 13.000 feet." (Dykes, The Genus 

 Iris, p. 27.)

66466. Iris setosa Pall. 



Arctic iris. 



This was originally described as an Asiatic 

 plant, but forms that can not be separated 

 from it are found in.North America, accordine 

 to W. R. Dykes (Irises, p. 64). At least half 

 a dozen forms come true from seed. Tte 

 peculiarity of this iris is that the standards 

 have dwindled until they are only small 

 points about half an inch long, but their dis- 

 appearance is usually counterbalanced by the 

 increased size of the falls. The color is usually 

 blue, but ome shades are so light as to be 

 almost gray.

66467. Lextcojcm verxum L. Amaryllidaeeae. 

 Spring snowflake. 



A hardy bulbous plant, native to central 

 Europe, with strap-shaped leaves, and a one- 

 flowered scape up to a foot long, bearing a white 

 flower tipped with green. 



LiGrsTROi delayayantm: Hariot. Olea- 



An evergreen shrub, about 6 feet high, with 

 long graceful tranches and dark shining-green 

 oval leaves. The white flowers, borne in downy 

 panicles, and the black fruits make the shrub 

 very ornamental. It is native to the moun- 

 tainous regions of Yunnan, China, and is prob- 

 ably suited for growing only in the southern 

 United States.
