252 Memoranda on the Peshawur Valley. [No. 3, 
The number of plants in the foregoing list amounts to 467, of 
which 348 are dicotyledonous, 105 monocotyledonous, and 14 aco- 
tyledonous, and these are distributed in about 320 genera, and 95 
natural orders ; thus the natural orders are to the genera as 1 to 3.45, 
and to the species as 1 to 4.91. 
377 out of the whole species have been specifically identified, 
but of these must be excluded 8 species with regard to the general 
distribution of which I have not sufficient data to render them 
available for any calculations as to the geographical relations of the 
Peshawur Flora. 
Of the 369 species thus left to be dealt with in this connexion, 
188 belong to the ordinary Indian Flora, while those plants which 
are found at various heights in the Himalaya, amount to 128, 39 
species being common to both the Himalaya and the plains. 
One circumstance which comes out strongly in the examination of 
the plants of Peshawur, is that here in the plains a great many 
species, (many of them European,) are indigenous, which to the 
Eastward cf the Punjab are only found in the Himalaya (or at 
similar heights in the Neilgheries, &c.) It has long been familiarly 
known that a considerable number of European species of herbaceous 
plants inhabit the plains of the N. W. Provinces. These generally 
flourish “in the cold season,” to use Dr. Royle’s phrase, but with 
regard to many of them, spring is the season of active growth, as I have 
been able to verify by observation during the early months of, 1861, 
1862 and 1863. All of these extend also into the Punjab, and the 
circumstance with which we are now concerned, goes to prove what 
otherwise would appear very likely, viz. : that the further North West 
we proceed, the greater is the number of (European and) Himalayan 
plants found in the plains. I shall here give a list of those plants 
which, near Peshawur, I have found below 1500 feet above the sea- 
level, but which have not been found in the plains of the North West 
Provinces, (to the East of the Sutlej)—many of them, so far as my 
information goes, having been found at such low elevations in the 
extreme North West Punjab only ;—but my means of obtaining data 
regarding the distribution of many of even the Indian species of 
plants, have, from my isolated position, and the want of libraries, 
&e.,—been so limited, that I have doubtless inserted some plants 
which ought to be excluded from this list.
