Kew collection. 
Distribution. The neighbourhood of Rawal Pindi and Peshawar. 
The purple form. Salt Range (Sodi Nuz), 1878, Aitchison (K). 
Mt Tilla, 1874, Aitchison (K).

“The purple form* was first collected on the Marqullah Pass by Vicary in the first Cabul campaign. 
It also grows on Mount Tilla and all through the Salt Range in the Punjaub. The yellow form 
is only found apparently in one locality in the Park at Rawal Pindi.” This information was given 
viva voce to Foster by Dr Aitchison, who added that he himself planted bulbs of the yellow form 
on Mount Tilla.

Observations. 
It should be noticed that Foster in Bulbous Irises, p. 81, says that the claw of fall does not 
bear wings, but in April, 1893 — the year after that in which the pamphlet was written — he received 
a dried flower from Dr Aitchison, and in this specimen the wings are distinctly visible. 
The Kew drawings show that the flowers of the yellow form are sometimes edged with red- or 
black-brown. 
It is unfortunate that this Iris does not appear to be in cultivation at present.

Distribution. It was discovered in 1899 by Mr Van Tubergen’s collector at a considerable elevation on the 
mountains of Eastern Turkestan in the neighbourhood of Tashkent The exact locality was not given by 
the collector. 
1 There seems to be some mistake here for the Kew specimen certainly appears to be the yellow-flowered form, and is said 
to be so in MS. attached.
