lapping, inflated, glaucous, striate, tinged with rose colour, 

 acuminate ; spathes usually two-flowered, similar to the 

 bracts but more inflated and more rosy, especially on the 

 margins ; pedicels not quite | in. long, about equalling 

 the tube of perianth ; perianth with throat slightly 

 dilated above the junction of the style, falls oblong, 2f 

 in. long, f in. wide, rich cream colour, beautifully marked 

 with fine lines of yellow on the claw, and with dotted 

 veins of purple on the spreading blades ; standards 

 cream colour, somewhat shorter than the falls, widely 

 spreading, linear oblong ; stamens with filaments 2 in. 

 long, J^ in. wide, narrowing abruptly at the insertion of 

 the anthers ; anthers f in. long ; style slender, about | 

 in. long ; stigmas I J in. long including the crests which 

 are J in. long, laciniate on the outer edge, tinted with 

 pale rose colour ; stigmatic lip truncate slightly undulate ; 

 capsule oblong, tapering equally at both ends, valves

Miss Alice Eastwood, who is the Curator of the 

 Herbarium, says that this is an elegant Iris common in 

 the Redwood region of Mendocino country around 

 Ukiah. It has hitherto been included under /. 

 Doug/asiana, but it differs from all the Californian Irises 

 in the peculiar bract-clothed flower stems (except we 

 may assume /. bracteata). Mr Carl Purdy first detected 

 this Iris as distinct from /. Doug/asiana and it is therefore 

 named after him. It grows in similar clumps but is less 

 widely spreading. 



According to Mr Purdy this plant is illustrated in The 

 Garden, Aug. 14, 1897, under the name /. macrosiphon. 



13. I. sibirica, L. ; Red. Li/., t. 420; Reich. Ic.Fl. 

 Germ., t. 341. This is one of the commonest of Irises 

 always to be recognised apparently by its hollow stem. 1 

 It has a dense tufted habit. The leaves are green, not 

 rigid, finely ribbed I to 2 ft. long, \ to J in. broad. 



1 7. Delavayi also appears to have a hollow stem.
