From the elevated valley of Astore, between Cashmere 

 and Thibet, Vigne brought the following plants : Aconi- 

 tum heteropliyllum, Anemone discolor, Podopliyllum, Dian- 

 thus, Geranium, Epilobium, several Gentians, Swertia and 

 Ophelia Chirata, Polemonium cceruleum, and Dracocepha- 

 lum Royleanum. Here, far above the tree-limit, we find 

 the elevated plain Deosuh, at an altitude of 13,000', the 

 soil of which is rendered verdant by dwarf- willows and 

 alpine herbs, whilst the valley in which the Indus runs 

 in Thibet is bare, a few plants occurring only at the 

 snow-line. Falconer found here a new Rheum and two 

 species of Pyrola, which, as Royle remarks, are the only 

 Ericaceous plants in Thibet. Vigne' s plants from 

 Iskardo agree pretty accurately with the older collections 

 from Kunawar : Actaa, some Cruciferae, Silene Moor- 

 croftiana, Acer microphyllum, Myricaria, Biebersteinia 

 odora, Astragalacece, several Potentillce, Saxifraga steno- 

 phylla, Hippophde and Salsola. 



Jacquemont's work on his travels, which has been 

 mentioned above, is now complete, and affords extensive 

 contributions to our knowledge of India in a botanico- 

 geographical point of view, especially the flora of the 

 British Himalayas and those of Thibet (Journal, vol. i-iii. 

 Paris, 1841. Vol. v, Descriptions des Collections. Ib. 

 1844, 4to. 2 vols. plates). The admirably-kept journal 

 of this traveller, which is printed unaltered, contains, of 

 course in a fragmentary form only, the impressions pro- 

 duced by the character of the vegetation of the Himalayas, 

 and separate regions of India ; but in the last section of 

 the work, the more rare and new plants of Jacquemont's 

 herbarium are treated in systematic detail by Cambes- 

 sedes and Decaisne, and illustrated with 180 plates. 



In Lesser Thibet, J. travelled on the road to Ladak, in 

 the valley of Spiti, as far as Danker, where at an ele- 

 vation of 17,000', at the limit to vegetable life, he found 

 the new Anthemideous genus Attar dia, a Nepeta, and 

 an Urtica. The villages in the valley of Spiti, according 

 to Jacquemont, are situated on a higher level than that
