At the present time the only guide tothe Flora of Siam is the list 
compiled by Dr. Williams and published in Bull. Herb. Boiss. 
(1904-05), a list which, in view of more recent collections, must 
be regarded as very incompletely representing the flora of that 
country. At the time that Dr. Williams was compiling his list 
Northern Siam was practically unrepresented i in the Kew Herbarium, 
With the result that his list unduly emphasises the Malay Peninsula 
element in the flora. 
Quite recently, however, some very important additions have 
been made to our botanical knowledge of that part of the country. 
In 1904-05 Dr. C. C. Hosseus made a large collection of plants, 
chiefly in N. W. Siam, and a fairly complete set of his piants 
is preserved in the Kew Herbarium. Lately large collections 
have om and are still being received at Kew from Dr. A. F. G. 
Kerr from the same district but mostly from Doi Sootep, a 
mountain near Chiengmai. Dr. Kerr has the great sivatane 
of being resident in the district—an advantage which can 
hardly be overestimated when it is remembered that ane pid 
the district is practically unknown. This has enable 
who is a keen and careful collector, to forward very scasolie e 
material to Kew. The officers of the Siamese Forest Service have 
also commenced the botanical investigation of their districts, as 
shewn by a small consignment of specimens lately received. It is 
to be earnestly hoped that the officers concerned may pursue the 
good work thus begun. 
The present list which, it is hoped, may be completed this year, is 
to be regarded as additional to the list published by Dr. Williams. 
In order, however, to illustrate as fully as possible Dr. Kerr’s 
“introduction, dealing with the botany of his district, all Dr. Kerr’s 
specimens are quoted, whether the species has already appeared in 
Dr, Williams’ list or not. In cases where the species has already 
been included by Dr. Williams a reference will be found to his list. 
Besides the collections already referred to, a small collection made 
by Mr. D..O. Witt, chiefly in Southern Siam, and several specimens 
of the older collections which had been overlooked by Dr. Williams 
‘have been included.
