228 PLANTA SCHLAGINTWEITIAN A, 
mean resulting from my researches for Dalhousie in Chamba, height 
6850 feet, being 59°30°, that of Montpellier 59:5? F. With reference 
to daily and annual variation, the climate all over Kashmir is mild, 
and not too hot. The decrease of temperature with height, for this 
part of the Himalaya, is 410 feet for 1° F."* 
|. Acting on the suggestion of the traveller, I name this new species 
in honour of Dr. T. Forbes Watson, M.A., M.D., F.L.S., Reporter on 
the Products of India to the Secretary of State for India (* Index to 
the Native and Scientific Names of India and other Eastern Economic 
Plants and Products,’ London, 1866, etc. etc.), and various other im- 
portant contributions to Indian botany. 
“ Nepeta Sabinei, n. sp., has been met with, by my brother Adolphe, 
in Western Tibet, at 15,800 feet} on the Thale La Pass, in Balti, and, 
a second time, at 12,592 feet, on the Gue Pass. For the thermal con- 
ditions in Balti, at this height, we obtain from my general tables the 
following mean values for the seasons and the year :—Wiuter, 13:5? F. ; 
spring, 54? F.; summer, 30:5? F.; autumn, 34? F. ; year, 33? F. 
In judging of this climate, it must be kept in mind that the dryness, 
though not quite so excessive as in the regions of Tibet more to the 
east, is still very great. The illustrious name associated with this plant 
is that of General Sabine, author of works on terrestrial magnetism 
of world-wide fame, and for many years President of the London Royal 
Society. We are espeeially obliged to him with reference to our Indian 
researches, for the information we obtained from him personally, and 
for the pains he took in making the arrangements necessary for our 
journeys.” 
“ Buddleia Martii,n.sp. 1 found this in the Khassia hills, in autumn, 
1855. The height, though important enough to affect the climate 
materially, did not exceed on this route 4500 feet. , The lowest 
valleys where th e plant was found did not descend below 9800 feet. 
For Cherapunji, the sanitary station for Assam and eastern Bengal, at 
4125 feet of elevation, I obtained four years' careful meteorological 
* * Results, vol. iv. p. 548. : 
t Though it may be unexpected to meet with such highly developed plants 
at these heights, the elevation, as such, is nothing extraordinary for these 
tons. Various Polygonums were found at 15,000-17,000 feet, a Pri- 
? 00 feet,—compare Meissner and Klatt 
in the paper above quoted. The greatest height at which we met with the last
