78 THE BOOK OF THE IRIS 



linear ; spathes one-flowered ; ovary on stalk ; perianth- 

 tube very short ; limb white, I J in. long, faintly veined 

 with yellow and lilac ; blade of falls J in. broad, as long 

 as haft ; standards rather shorter. Native of Oregon.

 1175. Standing quite alone in point of colour, this Iris 

 is one of but two which have spreading standards. The 

 other is L laevigata, familiar in gardens under the name 

 /. Kaempferi, which is usually applied to the cultivated 

 forms. The rhizome is stout ; the leaves bright green, 

 I \ to 2 ft. long, J to I in. broad ; stems 2 to 3 ft. long, 

 and forked low down, bearing about three heads ; 

 spathes two to three flowered ; pedicels produced ; 

 perianth-tube yellowish, about an inch long ; limb 2 in. 

 long, of bright fulvous brown colour, very like that of 

 Hemerocallis fulva, all the segments spreading from below 

 the middle ; falls obovate-cuneate, f to I in. broad, with 

 reddish brown pubescence about the keel ; standards 

 shorter than the falls ; crests small and broad. Mr 

 Baker regards this plant as connecting the sections 

 Apogon and Pogoniris. It flowers late in June, is easily 

 cultivated, but does not flower freely. The rhizomes 

 must be kept strong, by removing the weaker, otherwise 

 it may not flower at all. I grow it and flower it on a 

 mound of the bog garden, where the roots can reach 

 water. In some gardens it grows on an ordinary border, 

 but it is a moisture-loving plant. It is a native of the 

 United States, principally in the south, but is quite 

 hardy.

 Fl. des Serres, t. 2073-4. Not only is this one of the 

 finest of all Irises, but it is also one of the finest hardy 

 plants that can be grown. It has a close tufted habit. 

 The leaves are green, I to ij ft. long, 1 to f in. broad.
