BOOTAN. 



side, on which springs are rare. No Thibaudias occurred on the 

 other side, Euphorbia was confined to the Woollakkoo side, as also 

 Primula, etc. etc. The chief cultivation about Woollakkoo is of wheat, 

 but from the mode of cultivation the plant is evidently adapted for 

 irrigation ; rice is also cultivated. This is perhaps its maximum 

 height. The hills around are covered here and there with snow, and 

 must therefore be above 10,000 feet high. The highest were to the 

 north-west. 



The river is of moderate size, fordable in most places, but still 

 well supplied with wooden bridges. Fish, in shoals too, were seen 

 here and there. 



May Wth. — Our march continued down this river throughout : we 

 left its banks once or twice owing to ascending some hundred feet 

 above its bed, occasionally it spread out, but generally was confined 

 between the rocks. Its banks in some places were planted with weep- 

 ing willows. The vegetation throughout was much the same. The 

 most common plants were Rosa, this literally abounds, Pinus pendula, 

 Viburnum grandiflora, a Symphoria ! Crataegus 2 species, Mespilus 

 microphyllus, Lantonea, Jasminum luteum, Berberis asiatica and obo- 

 vata, Plectranthus canus, Elseagnus fragrans, Stellaria cana, Colqu- 

 hounia, Indigofera sp. altera, Baptisia did not re-appear, Euphorbia 

 continues, as does the Celastrus noticed yesterday, which commences 

 at 8,500 feet. 



Cycnium re-appears, it is in fruit, the cotyledons are not condupli- 

 cate. In the fields Stachys, Potentilla (common), Brumus, Lamium 

 of Khegumpa, Cynoglossum, Thlaspi, Datura in waste places, Cona- 

 ria, rare, Imperata ! Scabiosa of Bulphai. 



A low shrub abounded on the road sides and walls, having all 

 the characters of Plumbago, a Lantonea likewise abounded, Fragaria, 

 Swertia, Taxaxacum, Cardamina lilacina, Herminu sp., Marchantia, 

 Astragalus, Ranunculus, Carex, Poterltilla supina, Potamogeton, Cle- 

 matis grata, Poplars were seen ; of these, Taxaxacum very common, 

 Quercus robur re-appears towards Lamnoo, as well as Juglans and 

 Populus. 



Weeping cypresses about villages, Hordeum hexastichum is com- 

 monly cultivated, A. Buddlaea floribus lilacinis noticed yesterday was 

 found, its range is 8,500 to 7,500 feet, Zanthoxyla here. 



A cuckoo was shot ; this bird would seem to be as in Europe 

 attended by the Yunx, at least a cry very similar to that of that bird 

 was heard. Lysimachia of Punukha, Campanula re-appears.
