FLORA OF TIBET OR HIGH ASIA. 139 
Festuca valesiaca, F. nitidula, F. sibirica, and Elymus sibiricus. 
In the valley which they descended, T'riglochin palustre was met 
with, and this was afterwards found at an elevation of 15,000 ft. 
associated with 7’. maritimum, Crambe cordifolia, Glaux maritima, 
and Hurotia ceratoides. At the head of a ravine near the Sutlej 
(14,820 ft.) they found Chamerhodos sabulosa, Aster mollius- 
culus, Deyeuxia compacta, Stipa Eversii, E. mongholica, Ory- 
zopsis @quiglumis, and Lasiogrostis mongholica. Lower down 
(13,350 ft.) the largest shrub was Myricaria elegans, here growing 
to a height of five or six feet with stems often three or four 
inches in diameter. The dama (Caragana pygme@a) was usually 
luxuriant, rising to three feet or more. Clematis graveolens, 
Crepis glauca, Tanacetum gracile, Artemisia salsoloides, A. 
sacrorum, A. Roxburghiana, and Christolea crassifolia were also 
collected here. On the banks of a stream near Ligchephu 
Hippophaé Rhamnoides occurred full of berry. At Gyanima 
(Nima Khar), near a small lake at a lower elevation, the soil was 
covered with green turf, intersected by numerous small streams ; 
and Ranunculus aguaticus, R. Cymbalarie, Hippuris vulgaris, 
two species of Gentiana, and Primula tibetica, not exceeding an 
inch in height, were found in abundance. In the ravines near 
the lake of Rakas Tal (15,000 ft. and upwards) a small willow, 
Salix sclerophylla, was not uncommon, and Rheum Moor- 
croftianum, Gentiana nubigena, Lagotis glauca, Arenaria Stracheyi, 
and Pleurospermum were collected or observed. The vegetation 
along the southern shore of Rakas Tal and between the lakes 
was excessively meagre, and no novelties were added to the 
collection. Caragana pygmea, Potentilla sericea, Thylacospermum 
ruptfragum, Silene Moorcroftiana, Dracocephalum heterophyllum, 
Nepeta tibetica, N. supina, Oxytropis Stracheyana, Aster mollius- 
culus, Senecio coronopifolius, Artemisia Stracheyi, Tanacetum 
sp., Lactuca Lessertiana, Androsace villosa, Sedum fastigiatum, 
Draba lasiophylla, Delphinium ca@ruleum, and Allium Jacque- 
montii, together with a few grasses and sedges, would nearly 
complete the flora of this desert region. In the valley of the 
Karnali river there was a comparatively luxuriant vegetation. 
Descending from Gunda Yaukti, Biebersteinia Emodi, Euphorbia 
tibetica, Scirpus Caricis, and Agropyron longearistatum were 
added to the collection. Between Chirchun and Shelong, Urtica 
hyperborea was found, probably above 17,500 ft. ;
