84 THE BOOK OF THE IRIS 



The culture of all varieties is very easy on any bed or 

 border. There is a white form, and also one of soft 

 lavender, known as A. W. Tait. A very fine spurla is 

 called Dorothy Foster. 



32. I. Guldenstaediana, Lepech ; /. Mophila, Pallas ; 

 /. stenogyne, Red. LiL, sub. t. 310. I follow Baker in 

 treating this as a distinct species. Description may be 

 regarded as the same as for /. spuria, except in the 

 following differences leaves green, ensiform, \ to f in. 

 broad ; flowers pale yellow (in the type) ; falls \ to f 

 in. broad; style branches I to l| in. long. 



Like the preceding this does well on any bed or 

 border.

 This and the two following form a very natural group, 

 having the same habit and general appearance, with rich 

 green and robust foliage. They are the only -broad- 

 leaved Apogons with beaked, strongly ribbed fruits and 

 large standards. This species differs from the other 

 yellow flowered kind by having standards which do not 

 exceed | in. in width. The rhizome is stout ; the 

 leaves green, hardly at all glaucous, ij to 2 ft. long, 

 | to i in. wide. The stem is 3 to 3^ ft. long, stout, 

 with several reduced leaves, and two sessile heads below 

 the terminal one ; spathes 2 to 3 flowered, 3 to 4 in. 

 long ; valves green lanceolate ; pedicels long. The 

 perianth-tube is as long as the ovary, limb bright yellow, 

 2 J to 3^ in. long ; falls with an oblong blade an inch 

 broad ; standards, shorter oblanceolate, under \ in. 

 broad; style branches ij to ij in. long; crests deltoid. 

 A native of the Western Himalayas. It flowers in July, 

 rather later than its two relatives, and does well on an 

 ordinary border, but in the Cambridge Botanic Garden 

 it does not flower freely. At Kew a variety intermedia 

 is cultivated.
