210 
specimens from the commencement of the campaign. He includes 
a few species collected in 1894 by Capt. (now Col.) Sir Francis 
Younghusband, : More recently an extensive, carefully 
by other collectors. 
In Mr. Duthie’s essay six species are enumerated, of which three 
are correctly identified, J. Balsamina, I. Roylei, and I. brachycentra; 
I. amphorata, Edgew., is I. Lehmanni; I. laxiflora, Edgew. and 
I. scabrida are, I think, both LZ. Edgeworthii. 
~ The North-West Himalayan flora which extends from the Nepal 
frontier to Afghanistan contains, as at present known, nearly 40 
species of Impatiens of which only about eight have been found 
east of Nepal, in Sikkim, where about 80 species in all have been 
collected. No doubt many both of the N.W. and Sikkim species 
enter Nepal, which itself must contain many endemic forms of the 
genus in the thousand miles of the Himalaya that it covers, and 
which are a terra incognita geographically and botanically. Of 
the Chitral species two alone, J. Balsamina and I. Thomson, are 
found eastwards as far as Sikkim. 
Returning to the north-west, the Chitral Balsams no doubt enter 
the conterminous Afghan northern province of Kaffristan and there 
disappear, the climate of the western and southern regions of that 
kingdom, as of Persia, being prohibitive. No Himalayan member 
reappears in the Caucasus, where the only species known to me is 
I, nolitangere, L., which ranges continuously from Britain to Japan 
but nowhere enters India. It isremarkable that J. bicolor, Royle, 
which is perhaps the most common N.W. Himalayan species at 
4000 to 11,000 ft., has not been found in Chitral. 
To the following list of Chitral species I have added their 
distribution and brief diagnoses which will enable an amateur in 
Chitral to recognise them. The leaves of all, except I. Roylei, are 
alternate. 
A. Inflorescence simply pedicelled in the axils of the leaves. 
* Flowers white, rose-pink or purplish. 
1. I. Balsamina, L.; leaves lanceolate, serrate, flowers pink, 
capsule short, densely tomentose. 
Alt. 4000-5000 ft. Hamilton, Toppin. 
Distrib. throughout India, Malaya, China. 
B. Inflorescence peduncled, peduncles 2—many-flowered. 
* Flowers white, rose-pink or purplish. 
2. I. Roylei, Wahl.; leaves opposite, alternate, and whorled, 
serrate, flowers white and pink or purple, capsules short, clavate, 
glabrous, deflexed. 
Alt. 6000-10,000 ft., Gatacre. 
Distrib. southward to Murree and eastward to the Nepal frontier,
