There are also some few Mosses present in the collections. These have been determined by Dr. V. F. BROTHERUS and Dr. N. BRYHN and are listed below.
The collections brought home by Dr. Hedin do not claim to be exhaustive for the regions where he travelled. He had to endure too many hardships and to travel under such circumstances that it was impossible to employ any considerable time for collecting, nor was it possible to carry any voluminous collection. It is really wonderful that he has been able to make any collection at all, and one cannot refrain from admiring his energy in bestowing time upon botany, working as he was in some of the most inaccessible tracts of the earth. But apart from the difficult conditions under which the collection was made, it has real value since very little is known about the vegetation of those parts of Asia.
I wish here to thank Dr. Hedin for the honour he has done me in confiding to me the publication of his botanical material. I also wish to thank my collegues for having spared no labour to make the most of the material they have had in their hands.
