north as Sabathoo and Deyra beyond the Choor Mountain, being a tree much esteemed 
by the natives of India for the fragrance of its flowers and their use in religious 
ceremonies. Seven species of Michelia have been found in Nepal, whence the genus 
extends southwards to Java, where the original species of Janglietia is found, of 
which a representative, Magnolia insignis of Dr. Wallich, also exists in Nepal. 
Magnolia pterocarpa, Roxb., existing in the latter, as well as in the mountains above 
Silhet, Dr.Wallich proposes forming into a new genus, Sphenocarpus. Hence we per- 
ceive, that in India Michelia chiefly prevails, while in China and North America, between 
which the rest of the family are distributed, Magnolia is the most prevalent genus. It 
may be further remarked, that though in the latter the Magnoliacee extend from 20° to 
40° of N. latitude, and nearly as high in China and Japan, they hardly reach beyond 
27° in India or its mountains. This is probably owing to the plains being both too hot 
and too dry before the accession of the rainy season, and the cold of winter too consider- 
able even in the vallies of the Himalaya to the northward of that Jatitude. 
The Nepal Magnoliacee being highly ornamental, and at the same time useful timber 
trees, their introduction into England would be highly desirable, but it is much to be 
feared that, if the winter be not too severe, the spring is too changeable for plants accus- 
tomed to a constantly regular rise and fall of temperature. In the south of Europe 
they would certainly succeed, and perhaps also on the coast of Devonshire, where the 
extremes of temperature are modified by proximity to the ocean. The Chinese and 
American species of this order might easily be introduced into the places where their 
congeners flourish in Nepal ; and as the barks of both Magnolia glauca and Liriodendron 
tulipifera-are, like others of the order, possessed of bitterness, and useful as tonics, the 
naturalization of these trees would be useful in India. 
4, ANONACE#. 
The Anonacez, which form so magnificent a feature of the East-Indian Herbarium, 
consisting of nine genera and about eighty species, are hardly to be seen in the author's 
collection ; indeed, if it were not for the effects of cultivation, not a single species would 
probably be found in it. The species of this family are distributed over ‘the equinoctial 
parts of Africa, America, and Asia, and though of the two latter each has genera peculiar 
to itself, Anona and Guatteria are common to both ; and these, with Artabotrys and 
Uvaria, have numerous species in India, spreading from the Peninsulas to Silhet, whence 
a few straggle upwards as far as the hills about Monghir in 25° of N. latitude. The 
species found in more northern provinces, as Uvaria longifolia, the debdaroo of the 
Hindoos, have evidently been introduced from the south; and though species of all the 
genera succeed in the Botanic Garden as far north as Saharunpore, the only species 
which I have found within the Himalaya is Guatteria velutina, but in so suspicious 
a place, the banks of the Ruenka Lake, a little to the northward of Nahn, that, sol withe 
standing it having been shown, p. 12, that the jungly tract along the foot of the. Hima- 
laya is favourable to the northward extension of tropical plants, I suspect this must have
