2 Flora of the Malayan Peninsula. 
on the very day that Part 21—the last one of Vol. [V—appeared, Mr. 
Gamble is alone responsible for it. He has been promised help by va- 
rious Botanists, and especially by Major A. T. Gage, I.M.S., the present 
Superintendent of the Royal Botanic Garden, Calcutta; and hopes 
that with this kind assistance the whole work may soon be fully 
completed. 
The present contribution contains the account of the Families 
No. 93 Nyctaginacee, No. 94 Amarantacee, No. 95 Polygonacee, 
No. 97 Aristolochiacez, No. 99 Chloranthacee, No. 102 Lauracee and 
No. 103 Hernandiacez, all the work of Mr. Gamble except No. 95 
Polygonacee which has been contributed by Major Gage. The seven 
Families dealt with contain 33 genera and 189 species, of which 1 
genus and 78 species were new. The newspecies have been published 
in the Kew Bulletin. 
In accordance with the Rules adopted by the Vienna Conference, 
the measurements in this volume will be given in the metric system: 
and it is hoped that this change will not prove an inconvenience.
