différent parts of our Empire, but is also full of suggestion for 
possibilities of development. The botanist who wishes to work 
at a problem which may yield results of economic value will find 
numerous hints in the following pages. ere is ample oppor- 
tunity for work on physiological, chemical, anatomical or taxo- 
nomic lines; and there are also problems wicali should interest 
the Mendelian. The remarkable differences in yield of the 
economic product in oui allied species, or in ‘varieties and 
forms of one and the same species, or in plants of the same form 
when grown under different conditions of climate or soil, afford 
subjects for investigation. The systematist may do good service 
by monographic study of such groups, and by careful diagnosis 
of the species and varieties may enable the man in the field to 
discriminate the more valuable forms from those which are of 
ific identity of the useful plant is unknown; the botanical 
collector may solve such problems, and also increase our know- 
ledge of the habitat and range of distribution of useful plants, 
“ well as add to their number. To the botanist who is*willing 
o help on matters after the war by taking up work which 
eer or indirectly may be of economic value this Kew List 
indicates many paths of widely varying interes 
The List will also be useful for general he esioe. Botanists 
associated with various institutions frequently receive queries of 
an economic nature which are answered with some difficulty or 
only at the cost of a search throu h very scattered literature. 
Probably most of these queries could be easily answered at Kew, 
but it will be a sav ing of time and labour “ round to have the 
information, now supplied by the List, ready to hand and thus 
to render available for workers at- home et Friis an epitome 
of the knowledge which has been gathered together at one centre.
