BOOTAN. 



Salix pendula about villages. After leaving Panga we came on to a 

 place called Minzapeeza, here Adiantum, Aspidium ? Hamamelidea, 

 Cedrela ? Rhus, Galium, Tussilago, Saxifraga ligularis, Valeriana 

 violifolia, Smilax flexuosa, Aruncus, Sarcococea, Azalea. 



Rhododendron minus recommenced after leaving the river towards 

 Panga, a straggling cedar or two occurred, Populus rotunchfol. very 

 common, Gaultheria arborea. 



About Panga, Lithospermum, Oxalis corniculata, Umbellifera, from 

 the flowers of which moud is made, Rubus, Arabis, Taxacum, Dipsa- 

 cus. 



Beyond the waterfall the Quercus robur became common, forming 

 beautiful woods, it continued throughout until we re-descended to the 

 river, range 7 to 7,500 feet. In these woods formed likewise by 

 Pinus pendula, Convallaria cirrhosa appeared, Rubia cordifolia, hispida, 

 Paris polyphylla, Aralia cissifolia, Mitella, Ribes ! Spiraea, Asparagus, 

 Epipactis, Avularia, Houttuynia ! Arum viviparum on rocks, Duches- 

 mium, Populus oblonga occurred also, Coriaria ! Hedera common, 

 Benthamia common.

 on rocks, Eriophon ditto, Campanula cana, Pinus pendula, Rosa, 

 Convallarium cirrhosa, Polygonum robustum, foliis cordatis. 



The ascent up to 7,500 feet, was marked by similar vegetation : 

 up to this point the prevailing shrubs gradually disappeared, they 

 were never so common as about Panga. Quercus robur having ceased, 

 was succeeded by Quercus ferriuginea, which is much like Quercus 

 ilecifolia, and has very coriaceous leaves, this again at 7,500 feet, was 

 succeeded by Quercus ilecifolia, Dipsacus up to this, Pteris aquilina, 

 Gaultheria arborea. 



At 7,600 feet, Rhododendron oblonga, a most beautiful species, 

 Calyce discoideo commenced, as also Rhodora deflexa and Rhodora- 

 cea ochrolenea, which is, I think, that I before noticed as R. elliptica, 

 foliis basi cordatis subtus argenteis et punctatis, Euphorbia occurs 

 also here, as also the Rosa, Berberis asiatica. 



At 8,000 feet, the trees were covered with grey lichens, and 

 assumed the usual highly picturesque appearance : noticed Primula 

 Stuartii in flower (Symphoria! ceased), Euphorbia, Gaultheria num- 

 mularifolia commences, Artemisia major, Crataegus odoratus con- 

 tinues, Saxifraga ligularis common up to this, Ribes commences,
