178 THE BOOK OF THE IRIS 



median tooth usually the longest, spreading horizontally. 

 The style-arms are rather more than an inch long, by 

 not quite half an inch in breadth ; the stigma is con- 

 spicuous and tongue-shaped ; crests large and deltoid. 

 The plant is pleasing, though not exceedingly hand- 

 some ; it flowers at the same time as /. reticulata, form- 

 ing an agreeable contrast. It was introduced by the 

 firm of C. G. Van Tubergen, jun., but native country is 

 not recorded. Cultivation may be regarded as that of 

 its allies.

 Garden, June 8, 1901, p. 411. A charming Iris, dis- 

 tinctly new for garden purposes, and deserving specific 

 rank. Its habit is that of /. caucasica, and it agrees also 

 in the size, shape, arrangement, and horny margin of 

 the leaf, but the surface is perhaps more glistening 

 and without the glaucous sheen of that species. The 

 flowers, four to six to the stem, agree also in being 

 sessile, but in colour they are quite different, being 

 lavender or some similar tint of purple, with blotches 

 of white mingled with marks of deeper lavender on the 

 fall. The general form of the flower is that of /. cauca- 

 sica, but it is rather smaller, and the lateral expansions of 

 the claw of the fall are less marked and not transparent, 

 thus in some respects approaching /. orchioides. The 

 spathe-valves again are narrow, as in /. orchioides. and 

 not inflated. The crests are triangular and small, as in 

 orchioides, not large and quadrate, as in /. caucasica. It 

 is in fact intermediate between these two species. Is 

 native on the mountains of Eastern Turkestan, whence 

 it was introduced by Messrs C. G. Van Tubergen, 

 being named after the well-known patroness and prac- 

 titioner of horticulture. Cultivation is no doubt the 

 same as for its allies.
